I am having a problem with reading the files and subfolders. My code reads fine for the given fixed source path, E:\\Folder\\test\\test2.
There are many folders in the test, like test2, test3, test4, etc. I want to extract the data files in the main folder, test.
For example, I want to extract the files in test, so I want to read all the files contained in the test instead of writing my code for test3, test4 and many. And I want to extract and write all the files as same source structure on another drive.
like, if the source structure is like E:\\Folder\\test\\test2 then the destination structure should be like C:\\Folder\\test\\test2
Is there any way to do this?
Here is my code,
private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
{
DateTime dt = dateTimePicker1.Value;
txtSelectedDate.Text = dt.ToString("yyyyMMdd");
selectedDate = txtSelectedDate.Text;
}
private void button2_Click(object sender, EventArgs e)
{
DateTime stdate = Datetimepicker1.value;
while (stdate <= DateTime.Now)
{
txtSelectedDate.Text = stdate.ToString("yyyyMMdd");
selectedDate = txtSelectedDate.Text;
string DayBgSpot = "E:\\Folder\\test\\test2";
string DayBgSpotDestination = "E:\\Folder1";
int DT = int.Parse(txtSelectedDate.Text);
FileReader Reader = new FileReader();
FileReader Reader1 = new FileReader();
Reader.OpenDirectory(DayBgSpot);
Reader.ReadNaster();
string path = DayBgSpotDestination + "\\" + txtSelectedDate.Text + ".txt";
StreamWriter Strwriter = new StreamWriter(path);
try
{
while (Reader.iMaRecordsLeft > 0)
{
string SecName = Reader.sMaSecName;
string Symbol = Reader.sMaSecSymbol;
Symbol = prefix + Symbol;
int abc = 0;
Reader.OpenSecurityByName(Reader.sMaSecName);
if (Reader.iSeRecords > 0)
{
while (Reader.iSeRecordsLeft > 0)
{
Reader.ReadDay();
float O = Reader.dSeo;
float H = Reader.dSeh;
float L = Reader.dSel;
float C = Reader.dSec;
double V = Reader.dSeV;
double OI = Reader.dSrest;
string T = Reader.iSeTime.ToString();
string D = Reader.iSeDate.ToString();
if (int.Parse(D) == DT)
{
string a = string.Concat(SecName, ",", Symbol, ",", D, ",", T, ",", O, ",", H, ",", L, ",", C, ",", V, ",", OI);
if (SecName != "" && V != 0)
{
Strwriter.WriteLine(a);
}
}
}
}
abc++;
Reader.ReadNaster();
}
Reader.CloseDirectory();
Strwriter.Close();
Strwriter.Dispose();
}
catch
{
}
stdate = stdate.AddDays (1); // It will get next date till present
}
}
Something like
System.IO.DirectoryInfo baseFolder = new DirectoryInfo(#"c:\Folder\test\");
string destinationPath = #"e:\Folder\test\";
System.IO.DirectoryInfo[] subDirs = baseFolder.GetDirectories();
foreach (System.IO.DirectoryInfo dirInfo in subDirs)
{
string subFolder = dirInfo.Name;
System.IO.FileInfo[] fileInfos = dirInfo.GetFiles("*.txt");
foreach (System.IO.FileInfo fileInfo in fileInfos)
{
// Do something with the files
string writePath = destinationPath + subFolder + #"\" + fileInfo.Name;
// Write
}
}
If you are using .NET 4.0 this is one line:
var filepaths = Directory.GetFiles(path: #"C:\", searchPattern: "*pattern*", searchOption: SearchOption.AllDirectories);
Clearly, the root path and search pattern are not in line with the proposed sample, but my intention should clear.
I hope this helps

I'm using DirectoryInfo and the method GetFilesByExtensions
public IEnumerable<FileInfo> GetFilesByExtensions(DirectoryInfo dir, params string[] extensions)
{
if (extensions == null)
throw new ArgumentNullException("extensions");
IEnumerable<FileInfo> files = dir.EnumerateFiles();
return files.Where(f => extensions.Contains(f.Extension));
}
if there are existing files for example rectangle1.bmp rectangle2.bmp.....rectangle7.bmp
then when creating a new rectangle file on the hard disk i want it to be rectangle8.bmp
now it's trying to create another rectangle1.bmp and give exception and i don't want to delete the existing files but to create new ones.
and make it as much as possible generic. but the main goal is to create new files names according to those existing and continue the counting.
You can write a method that checks if the proposed name exists or not
string GetNextName(string baseName, string extension)
{
int counter = 1;
string nextName = baseName + counter + extension;
while(File.Exists(nextName))
{
counter++;
nextName = baseName + counter + extension;
}
return nextName;
}
and call it in this way:
rectangleName = GetNextName(#"d:\Rectangles\rectangle", ".bmp");
You can use linq and do everything in one statement like this:
DirectoryInfo di = new DirectoryInfo(#"D:\rectangles");
var maxIndex = di.GetFiles().Select(fi => fi.Name.Replace("rectangle","").Replace(".bmp", "")).Max(i => i);

I wrote a text file. The first item of each line from this text file supposed to be key and rest of the items are values. My text file looks like this-
Flensburg;Nordertor;Naval Academy Mürwik;Flensburg Firth
Kiel;Laboe Naval Memorial;Zoological Museum of Kiel University;Kieler Förde
Lübeck;Holstentor;St. Mary's Church, Lübeck;Passat (ship);Burgtor;Lübeck Museum of Theatre Puppets;Trave
For my project purpose, I need to create .json data for each values and store those vales into the key name folder.As I am very new handling this situation I am not getting the correct logic to do this. However I tried in the follwing way by which I can create the key name folder and and only one subfolder into it. But I need to create all values folder inside the key folder. How can I do it.
My POI class from which I read the text file as key value is-
public class POI
{
Dictionary<string, List<string>> poi = new Dictionary<string, List<string>>();
public bool ContainsKey(string key) { return this.poi.ContainsKey(key); }
public List<string> GetValue(string key) { return this.poi[key]; }
public void POIList()
{
foreach (string line in File.ReadLines("POIList.txt"))
{
string[] parts = line.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries);
poi.Add(parts[0], new List<string>());
poi[parts[0]] = new List<string>(parts.Skip(1));
}
}
}
in the form1.cs
private void button1_Click(object sender, EventArgs e)
{
JSON_Output Json = new JSON_Output();
Json.ToJsonForLocation(comboBox1.Text);
}
also I set selectedindexchange from combobox2
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
if (comboBox1.SelectedItem != null)
{
POI poi1 = new POI();
poi1.POIList();
string txt = comboBox1.SelectedItem.ToString();
if (poi1.ContainsKey(txt))
{
List<string> points = poi1.GetValue(txt);
comboBox2.Items.Clear();
comboBox2.Items.AddRange(points.ToArray());
}
}
}
now where the json file generated to sore the value is-
public void ToJsonForLocation(string name)
{
var startPath = Application.StartupPath;
string folderName = Path.Combine(startPath, "Text_ImageWithHash");
string SubfolderName = Path.Combine(folderName, name);
//string folderName = Path.Combine(startPath, "Text_ImageWithHash");
System.IO.Directory.CreateDirectory(SubfolderName);
string fileName = name + ".json";
var path = Path.Combine(SubfolderName, fileName);
var Jpeg_File = new DirectoryInfo(startPath + #"\Image\" + name).GetFiles("*.jpg");
POIData Poi=new POIData();
Poi.Shorttext = File.ReadAllText(startPath + #"\Short Text\" + name + ".txt");
Poi.GeoCoordinates=GeosFromString(startPath + #"\Latitude Longitude\" + name + ".txt");
Poi.Images=new List<string> { Jpeg_File[0].Name};
string json = JsonConvert.SerializeObject(Poi,Formatting.Indented);
File.WriteAllText(path , json);
}
This is my code output while running the program.
after clicking button 1 Text_image_withHash folder is generated in the configuration directory.
Now if I open the folder I can see fthe following folders which is the key value from text file
After enable button 2 for combobox two the values folder is generated but not in the key folder.but as usual way in the Text_Image_withHash.
But What I want to do is-
To create that kind of folder-structure, simply use a foreach-loop. And String.Split.
Required usings:
using System;
using System.IO;
using System.Text;
using System.Linq;
Example:
// basePath can be anything
var basePath = "C:\Something";
// assume "info" is your CSV.
var infoParts = info.Split(new[] { ';' }, StringSplitOptions.RemoveEmptyEntries);
if (infoParts.Length == 0)
{
return;
}
var rootPath = infoParts[0];
Directory.CreateDirectory(Path.Combine(basePath, rootPath));
foreach (var subPath in infoParts.Skip(1))
{
Directory.CreateDirectory(Path.Combine(basePath, rootPath, subPath));
}
Saving JSON-files into these directories could then simply be made by combining the paths in a similar fashion.
I would also suggest some sanitizing of your paths (such as replacing '/' and '\\' with '_' or '-'.
Example implementation:
public void POIList()
{
foreach (string line in File.ReadLines("POIList.txt"))
{
string[] parts = line.Split(new[] { ';' },
StringSplitOptions.RemoveEmptyEntries);
if (parts.Length == 0)
{
// Empty line or similar.
continue;
}
string cityName = parts[0];
poi.Add(cityName, new List<string>());
// Add the points of interest to local.
var points = new List<string>(parts.Skip(1));
poi[cityName] = points;
// basePath will have to be retrieved somehow. It's up to you.
string cityDirectoryPath = Path.Combine(basePath, cityName));
// Create a directory for the city.
Directory.CreateDirectory(cityDirectoryPath);
// Create sub-directories for points.
foreach (string point in points)
{
Directory.CreateDirectory(Path.Combine(
cityDirectoryPath, point));
}
}
}
I have just got my answer. This is the solution of the above question.
For POI Class :
public class POI
{
Dictionary<string, List<string>> poi = new Dictionary<string, List<string>>();
public bool ContainsKey(string key) { return this.poi.ContainsKey(key); }
public List<string> GetValue(string key) { return this.poi[key]; }
public void POIList()
{
foreach (string line in File.ReadLines("POIList.txt"))
{
string[] parts = line.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries);
if (parts.Length == 0)
{
// Empty line or similar.
continue;
}
string cityName = parts[0];
poi.Add(cityName, new List<string>());
// Add the points of interest to local.
var points = new List<string>(parts.Skip(1));
poi[cityName] = points;
var startPath = Application.StartupPath;
string folderName = Path.Combine(startPath, "FinalJson");
string cityDirectoryPath = Path.Combine(folderName, cityName);
Directory.CreateDirectory(cityDirectoryPath);
}
}
}
the the json output class
public void ToJsonForLocation(string CityName,string PoiName)
{
var startPath = Application.StartupPath;
string folderName = Path.Combine(startPath, "FinalJson");
string SubfolderName = Path.Combine(folderName, CityName);
System.IO.Directory.CreateDirectory(SubfolderName);
string fileName = PoiName + ".json";
var path = Path.Combine(SubfolderName, fileName);
var Jpeg_File = new DirectoryInfo(startPath + #"\Image\" + PoiName).GetFiles("*.jpg");
POIData Poi=new POIData();
Poi.Shorttext = File.ReadAllText(startPath + #"\Short Text\" + PoiName + ".txt");
Poi.GeoCoordinates = GeosFromString(startPath + #"\Latitude Longitude\" + PoiName + ".txt");
Poi.Images=new List<string> { Jpeg_File[0].Name};
string json = JsonConvert.SerializeObject(Poi,Formatting.Indented);
File.WriteAllText(path,json);
}
this is generated folder and file in this way-
The Final json file for all values
I have a folder that is filled with dwg files so I just need to find the latest version of a File or if a File has no versions then copy it to a directory. For example here are three files:
ABBIE 08-10 #6-09H4 FINAL 06-12-2012.dwg
ABBIE 08-10 #6-09H4 FINAL 06-12-2012_1.dwg
ABBIE 08-10 #6-09H4 FINAL 06-12-2012_2.dwg
Notice the difference is one file has a _1 and another has a _2 so the latest file here is the _2. I need to keep the latest file and copy it to a directory. Some files will not have different versions so those can be copied. I cannot focus on the creation date of the file or the modified date because in many instances they are the same so all I have to go on is the file name itself. I'm sure there is a more efficient way to do this than what I will post below.
DirectoryInfo myDir = new DirectoryInfo(#"H:\Temp\Test");
var Files = myDir.GetFiles("*.dwg");
string[] fileList = Directory.GetFiles(#"H:\Temp\Test", "*FINAL*", SearchOption.AllDirectories);
ArrayList list = new ArrayList();
ArrayList WithUnderscores = new ArrayList();
string nameNOunderscores = "";
for (int i = 0; i < fileList.Length; i++)
{
//Try to get just the filename..
string filename = fileList[i].Split('.')[0];
int position = filename.LastIndexOf('\\');
filename = filename.Substring(position + 1);
filename = filename.Split('_')[0];
foreach (FileInfo allfiles in Files)
{
var withoutunderscore = allfiles.Name.Split('_')[0];
withoutunderscore = withoutunderscore.Split('.')[0];
if (withoutunderscore.Equals(filename))
{
nameNOunderscores = filename;
list.Add(allfiles.Name);
}
}
//If there is a number after the _ then capture it in an ArrayList
if (list.Count > 0)
{
foreach (string nam in list)
{
if (nam.Contains("_"))
{
//need regex to grab numeric value after _
var match = new Regex("_(?<number>[0-9]+)").Match(nam);
if (match.Success)
{
var value = match.Groups["number"].Value;
var number = Int32.Parse(value);
WithUnderscores.Add(number);
}
}
}
int removedcount = 0;
//Whats the max value?
if (WithUnderscores.Count > 0)
{
var maxval = GetMaxValue(WithUnderscores);
Int32 intmax = Convert.ToInt32(maxval);
foreach (FileInfo deletefile in Files)
{
string shorten = deletefile.Name.Split('.')[0];
shorten = shorten.Split('_')[0];
if (shorten == nameNOunderscores && deletefile.Name != nameNOunderscores + "_" + intmax + ".dwg")
{
//Keep track of count of Files that are no good to us so we can iterate to next set of files
removedcount = removedcount + 1;
}
else
{
//Copy the "Good" file to a seperate directory
File.Copy(#"H:\Temp\Test\" + deletefile.Name, #"H:\Temp\AllFinals\" + deletefile.Name, true);
}
}
WithUnderscores.Clear();
list.Clear();
}
i = i + removedcount;
}
else
{
//This File had no versions so it is good to be copied to the "Good" directory
File.Copy(#"H:\Temp\SH_Plats\" + filename, #"H:\Temp\AllFinals" + filename, true);
i = i + 1;
}
}
I've made a Regex based solution, and apparently come late to the party in the meantime.
(?<fileName>[A-Za-z0-9-# ]*)_?(?<version>[0-9]+)?\.dwg
this regex will recognise the fileName and version and split them into groups, a pretty simple foreach loop to get the most recent files in a dictionary (cos I'm lazy) and then you just need to put the fileNames back together again before you access them.
var fileName = file.Key + "_" + file.Value + ".dwg"
full code
var files = new[] {
"ABBIE 08-10 #6-09H4 FINAL 06-12-2012.dwg",
"ABBIE 08-10 #6-09H4 FINAL 06-12-2012_1.dwg",
"ABBIE 08-10 #6-09H4 FINAL 06-12-2012_2.dwg",
"Second File.dwg",
"Second File_1.dwg",
"Third File.dwg"
};
// regex to split fileName from version
var r = new Regex( #"(?<fileName>[A-Za-z0-9-# ]*)_?(?<version>[0-9]+)?\.dwg" );
var latestFiles = new Dictionary<string, int>();
foreach (var f in files)
{
var parsedFileName = r.Match( f );
var fileName = parsedFileName.Groups["fileName"].Value;
var version = parsedFileName.Groups["version"].Success ? int.Parse( parsedFileName.Groups["version"].Value ) : 0;
if( latestFiles.ContainsKey( fileName ) && version > latestFiles[fileName] )
{
// replace if this file has a newer version
latestFiles[fileName] = version;
}
else
{
// add all newly found filenames
latestFiles.Add( fileName, version );
}
}
// open all most recent files
foreach (var file in latestFiles)
{
var fileToCopy = File.Open( file.Key + "_" + file.Value + ".dwg" );
// ...
}
You can use this Linq query with Enumerable.GroupBy which should work(now tested):
var allFiles = Directory.EnumerateFiles(sourceDir, "*.dwg")
.Select(path => new
{
Path = path,
FileName = Path.GetFileName(path),
FileNameWithoutExtension = Path.GetFileNameWithoutExtension(path),
VersionStartIndex = Path.GetFileNameWithoutExtension(path).LastIndexOf('_')
})
.Select(x => new
{
x.Path,
x.FileName,
IsVersionFile = x.VersionStartIndex != -1,
Version = x.VersionStartIndex == -1 ? new Nullable<int>()
: x.FileNameWithoutExtension.Substring(x.VersionStartIndex + 1).TryGetInt(),
NameWithoutVersion = x.VersionStartIndex == -1 ? x.FileName
: x.FileName.Substring(0, x.VersionStartIndex)
})
.OrderByDescending(x => x.Version)
.GroupBy(x => x.NameWithoutVersion)
.Select(g => g.First());
foreach (var file in allFiles)
{
string oldPath = Path.Combine(sourceDir, file.FileName);
string newPath;
if (file.IsVersionFile && file.Version.HasValue)
newPath = Path.Combine(versionPath, file.FileName);
else
newPath = Path.Combine(noVersionPath, file.FileName);
File.Copy(oldPath, newPath, true);
}
Here's the extension method which i'm using to determine if a string is parsable to int:
public static int? TryGetInt(this string item)
{
int i;
bool success = int.TryParse(item, out i);
return success ? (int?)i : (int?)null;
}
Note that i'm not using regex but string methods only.
Try this
var files = new My.Computer().FileSystem.GetFiles(#"c:\to\the\sample\directory", Microsoft.VisualBasic.FileIO.SearchOption.SearchAllSubDirectories, "*.dwg");
foreach (String f in files) {
Console.WriteLine(f);
};
NB: Add a reference to Microsoft.VisualBasic and use the following line at the beginning of the class:
using My = Microsoft.VisualBasic.Devices;
UPDATE
The working sample[tested]:
String dPath=#"C:\to\the\sample\directory";
var xfiles = new My.Computer().FileSystem.GetFiles(dPath, Microsoft.VisualBasic.FileIO.SearchOption.SearchAllSubDirectories, "*.dwg").Where(c => Regex.IsMatch(c,#"\d{3,}\.dwg$"));
XElement filez = new XElement("filez");
foreach (String f in xfiles)
{
var yfiles = new My.Computer().FileSystem.GetFiles(dPath, Microsoft.VisualBasic.FileIO.SearchOption.SearchAllSubDirectories, string.Format("{0}*.dwg",System.IO.Path.GetFileNameWithoutExtension(f))).Where(c => Regex.IsMatch(c, #"_\d+\.dwg$"));
if (yfiles.Count() > 0)
{
filez.Add(new XElement("file", yfiles.Last()));
}
else {
filez.Add(new XElement("file", f));
};
};
Console.Write(filez);
Can you do this by string sort? The only tricky part I see here is to convert the file name to a sortable format. Just do a string replace from dd-mm-yyyy to yyyymmdd. Then, sort the the list and get the last record out.
This is what you want considering fileList contain all file names
List<string> latestFiles=new List<string>();
foreach(var groups in fileList.GroupBy(x=>Regex.Replace(x,#"(_\d+\.dwg$|\.dwg$)","")))
{
latestFiles.Add(groups.OrderBy(s=>Regex.Match(s,#"\d+(?=\.dwg$)").Value==""?0:int.Parse(Regex.Match(s,#"\d+(?=\.dwg$)").Value)).Last());
}
latestFiles has the list of all new files..
If fileList is bigger,use Threading or PLinq
I'm having a bit of trouble passing this parameter to a class i have. Does anybody have any ideas?

// string[] files = Directory.GetFiles(retPath, "*.*", SearchOption.AllDirectories);
string pattern = " *[\\~#%&*{}/<>?|\"-]+ *";

Class 2's code:

{
public void FileCleanup(string fileNames)
{
string regPattern = " *[\\~#%&*{}/<>?|\"-]+ *";
string replacement = "";
Regex regExPattern = new Regex(regPattern);
}
What i want to do in SanitizeFileNames is do a foreach through the FileNames & FilePath and replace invalid chars (as defined in my Regex pattern). So, something along the lines of this:
using (StreamWriter sw = new StreamWriter(#"S:\File_Renames.txt"))
{
//Sanitize and remove invalid chars
foreach (string Files2 in filePath)
{
try
{
string filenameOnly = Path.GetFileName(Files2);
string pathOnly = Path.GetDirectoryName(Files2);
string sanitizedFilename = regEx.Replace(filenameOnly, replacement);
string sanitized = Path.Combine(pathOnly, sanitizedFilename);
sw.Write(sanitized + "\r\n");
System.IO.File.Move(Files2, sanitized);
}
//error logging
catch(Exception ex)
{
StreamWriter sw2 = new StreamWriter(#"S:\Error_Log.txt");
sw2.Write("ERROR LOG");
sw2.WriteLine(DateTime.Now.ToString() + ex + "\r\n");
sw2.Flush();
sw2.Close();
}
}
}
However, I'm having trouble passing the fileNames into my SanitizeFileNames class. Can anybody help me?
dataGridView1.Rows.Clear();
try
{
foreach (string fileNames in fileDrive)
{
if (regEx.IsMatch(fileNames))
{
string fileNameOnly = Path.GetFileName(fileNames);
string pathOnly = Path.GetDirectoryName(fileNames);
DataGridViewRow dgr = new DataGridViewRow();
filePath.Add(fileNames);
dgr.CreateCells(dataGridView1);
dgr.Cells[0].Value = pathOnly;
dgr.Cells[1].Value = fileNameOnly;
dataGridView1.Rows.Add(dgr);
new SanitizeFileNames().FileCleanup(fileNames);
}
else
{
continue;
}
}
}
I suppose you want to pass a dirty name to the FileCleanup function and get a clean out. Here is how you can do that :
public String FileCleanup(string fileNames)
{
string regPattern = " *[\\~#%&*{}/<>?|\"-]+ *";
string replacement = "";
Regex regExPattern = new Regex(regPattern);
...
return cleanName;
}
and use it in your code like this:
String cleanName = new SanitizeFileNames().FileCleanup(fileNames);
where you put the comment.
You can create a third class static class and add static variable called files “public static List<string> Files= new List<string>()” as example.
When you create the files add the same files to the static variable.
When you clean the files loop throw the static variable, and at the end clear it.
The parameter type should be an enumerable collection of some sort: a list or an array would do. Also, strings are immutable so you could return a list of cleaned up filenames:
public class SanitizeFilenames
{
public List<string> FileCleanUp(IEnumerable<string> filenames)
{
var cleanedFileNames = new List<string>();
var invalidChars = Path.GetInvalidFileNameChars();
foreach(string file in filenames)
{
if(file.IndexOfAny(invalidChars) != -1)
{
// clean the file name and add it to the cleanedFileNames list
}
else
{
// nothing to clean here
cleanedFileNames.Add(file);
}
}
return cleanedFileNames;
}
}
