C# ListBox copy to Folder

I'm a newbish C#er and here's my question:
What I want:
Copy mp3 files of the same Artist into the same Folder.
e.G. Nirvana - Song 1 & Nirvana - Song 2 into Folder "Nirvana".
What I've been doing so far:
Read ParantDirectory and List the ingredients into a Listbox. The Listbox shows only the Artist (of course its filtered(Substring(indexof"-"))). After the files have been read my tool create a Folder with the Artist name.
And there I'm struggling!
I need a snippet that copy all content of Nirvana* to the Nirvana Folder.
I really hope you girls and guys understand what I'm trying to do...
Thank you in advance!

I guess you have a List<FileInfo> containing your files? If so you can go with File.Copy like this:
void Button2Click(object sender, EventArgs e)
{
DirectoryInfo ParentDirectory = new DirectoryInfo(#"C:\Users\A7024985\Desktop\");
string interpret = f.Name.Substring(0, f.Name.IndexOf("-")).TrimEnd(' ');
string title = f.Name.Remove(0, interpret.Length+1).TrimStart(' ');
File.Copy(f.FullName, ParentDirectory
+ interpret
+ "\\"
+ title); //or f.Name
}
Copy("C:\Users\A7024985\Desktop\Nirvana-Teen Spirit.mp3" , C:\Users\A7024985\Desktop\Nirvana\Teen Spirit.mp3

A good way to do this is use the TagLib# library (see example here) to find the ID3 tags (Artist, Song, Album, etc...), and then create a collection of these, and then sort them, and then move them to a new folder based on the Artist.
var songList = new List<string>(); //Contains a list of song files. E.g. "Come As You Are.mp3", "Heart Shaped Box.mp3", "Smells Like Teen Spirit.mp3".
var tagLibFiles = new List<TagLib.File>();
tagLibFiles.AddRange(songList.Select(x => new TagLib.File(x));
var nirvanaSongs = tagLibFiles.Where(x => x.Tag.FirstAlbumArtist == "Nirvana").ToList();
foreach(var song in nirvanaSongs)
{
//Move the file to your Nirvana folder.
}

I am guessing listboxitem.ToString() contains the name of the artist.
Then:
var filestomove = ParentDirectory.GetFiles().Where(f=>f.Name.Contains(listboxitem.ToString()));
foreach(var file in filestomove){
File.Move(file.FullName,pfas+file.Nmae)
}

C# search all files in a directory that contain a string, then return that string

Using user input into a textbox, I want to search for which file in the directory contains that text. I would then like to parse out the information
but I can't seem to find the string or at least return the information. Any help would be greatly appreciated.
My current code:
private void btnSearchSerial_Click(object sender, EventArgs e)
{
dynamic dirScanner = #"\\mypath\";
string strSerial;
string strSID;
string strInputLine;
string strOutput;
strSerial = Convert.ToString(txtSerialSearch);
strSID = Convert.ToString(txtSID);
if (txtSerialSearch.Text != "" && txtSID.Text != "")
{
try
{
string[] allFiles = Directory.GetFiles(dirScanner);
foreach (string file in allFiles)
{
if (file.EndsWith(".txt"))
{
using (StreamReader sr = new StreamReader(file))
{
while (sr.Peek() >= 0)
{
strInputLine = sr.ReadLine();
if (strInputLine.Contains(strSerial))
{
strOutput = Convert.ToString(strInputLine);
lblOutput.Text = Convert.ToString(strOutput);
}
}
}
}
}
}
}
}

You seem quite lost. Why are you using a dynamic when a string is all that you need? Your code has too many unnecessary variables and convertions. Here's a much simpler way to do it. I don't know what you want the label to have if there are many matching lines, here I'm only placing the first one there:
string dirScanner = #"\\mypath\";
if (string.IsNullOrWhiteSpace(txtSerialSearch.Text) || string.IsNullOrWhiteSpace(txtSID.Text))
return;
string[] allFiles = Directory.GetFiles(dirScanner, "*.txt");
foreach (string file in allFiles)
{
string[] lines = File.ReadAllLines(file);
string firstOccurrence = lines.FirstOrDefault(l => l.Contains(txtSerialSearch.Text));
if (firstOccurrence != null)
{
lblOutput.Text = firstOccurrence;
break;
}
}

I have implemented the same using Regular Expressions. You need to use namespace using System.Text.RegularExpressions;
string strSerial = #"Microsoft";
Regex match = new Regex(strSerial);
string matchinglines = string.Empty;
List<string> filenames = new List<string>(Directory.GetFiles(textBox1.Text));
foreach(string filename in filenames)
{
//StreamReader strFile = new StreamReader(filename);
string fileContent = File.ReadAllText(filename);
if(match.IsMatch(fileContent))
{
label1.Text = Regex.Match(fileContent, strSerial).ToString();
break;
}
}

Use System.LINQ:
var list_of_files_that_match = Directory.EnumerateFiles(dir).Where(delegate (string t)
{
return System.IO.File.ReadAllText(t).Contains(your_text);
}).ToList();
This worked for me. Quick and simple.

How to store all values in the key named folder using c#

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

Read lines at different indexes

Here is some code i put together to search for numbers in a text file. It work's great for what i'm trying to do. right now it finds 7 locations and i need to read the lines at the 7 different indexes. what might be the best way to start this. Thanks, this is in C#.
private void button1_Click(object sender, EventArgs e)
{
richTextBox1.Text = "";
using (OpenFileDialog dlgOpen = new OpenFileDialog())
{
//long count = 0; string line;
//bool start = false;
//string line;
List<String> LinesFound = new List<string>();
// Available file extensions
dlgOpen.Filter = "All files(*.*)|*.*";
// Initial directory
dlgOpen.InitialDirectory = "C://bin";
// OpenFileDialog title
dlgOpen.Title = "Load";
// Show OpenFileDialog box
if (dlgOpen.ShowDialog() == DialogResult.OK)
textBox1.Text = dlgOpen.FileName;
{
string str = System.IO.File.ReadAllText(dlgOpen.FileName);
Regex reg = new Regex("333333");
Match sat = reg.Match(str);
while (sat.Success)
{
richTextBox1.Text += (sat.Index + " "); //shows index where 333333 is
sat = reg.Match(str, sat.Index + sat.Length);
{
{
}
}
}
}
}
}

You can use ReadAllLines instead of ReadAllText, and match each line one by one, use a int[] variable to store all your matching line index.
var lines = File.ReadAllLines(AppDomain.CurrentDomain.BaseDirectory + "/files/file.txt");
Regex reg = new Regex("333333");
string str;
for(int i =1; i<lines.Length;i++)
{
str = lines[i];
Match sat = reg.Match(str);
if (sat.Success)
{
richTextBox1.Text += (i + 1 +" "); //shows index where 333333 is
}
}

Trouble passing a parameter to a class in C#

I'm having a bit of trouble passing this parameter to a class i have. Does anybody have any ideas?
Class 1's code:
public void DriveRecursion(string retPath)
{
//recurse through files. Let user press 'ok' to move onto next step
// string[] files = Directory.GetFiles(retPath, "*.*", SearchOption.AllDirectories);
string pattern = " *[\\~#%&*{}/<>?|\"-]+ *";
//string replacement = "";
Regex regEx = new Regex(pattern);
string[] fileDrive = Directory.GetFiles(retPath, "*.*", SearchOption.AllDirectories);
List<string> filePath = new List<string>();
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);
\\I want to pass fileNames to my FileCleanup Method
\\I tried this:
\\SanitizeFileNames sf = new SanitizeFileNames();
\\sf.Add(fileNames); <-- this always gets an error..plus it is not an action i could find in intellisense
}
else
{
continue;
}
}
}
catch (Exception e)
{
StreamWriter sw = new StreamWriter(retPath + "ErrorLog.txt");
sw.Write(e);
}
}
Class 2's code:
public class SanitizeFileNames
{
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;
}
}
