My image URL is like this:
photo\myFolder\image.jpg
I want to change it so it looks like this:
photo\myFolder\image-resize.jpg
Is there any short way to do it?
This following code snippet changes the filename and leaves the path and the extenstion unchanged:
string path = #"photo\myFolder\image.jpg";
string newFileName = #"image-resize";
string dir = Path.GetDirectoryName(path);
string ext = Path.GetExtension(path);
path = Path.Combine(dir, newFileName + ext); // #"photo\myFolder\image-resize.jpg"
You can use Path.GetFileNameWithoutExtension method.
Returns the file name of the specified path string without the extension.
string path = #"photo\myFolder\image.jpg";
string file = Path.GetFileNameWithoutExtension(path);
string NewPath = path.Replace(file, file + "-resize");
Console.WriteLine(NewPath); //photo\myFolder\image-resize.jpg
Here is a DEMO.
This is what i use for file renaming
public static string AppendToFileName(string source, string appendValue)
{
return $"{Path.Combine(Path.GetDirectoryName(source), Path.GetFileNameWithoutExtension(source))}{appendValue}{Path.GetExtension(source)}";
}
I would use a method like this:
private static string GetFileNameAppendVariation(string fileName, string variation)
{
string finalPath = Path.GetDirectoryName(fileName);
string newfilename = String.Concat(Path.GetFileNameWithoutExtension(fileName), variation, Path.GetExtension(fileName));
return Path.Combine(finalPath, newfilename);
}
In this way:
string result = GetFileNameAppendVariation(#"photo\myFolder\image.jpg", "-resize");
Result: photo\myFolder\image-resize.jpg
Or the File.Move method:
System.IO.File.Move(#"photo\myFolder\image.jpg", #"photo\myFolder\image-resize.jpg");
BTW: \ is a relative Path and / a web Path, keep that in mind.
You can try this
string fileName = #"photo\myFolder\image.jpg";
string newFileName = fileName.Substring(0, fileName.LastIndexOf('.')) +
"-resize" + fileName.Substring(fileName.LastIndexOf('.'));
File.Copy(fileName, newFileName);
File.Delete(fileName);
try this
File.Copy(Server.MapPath("~/") +"photo/myFolder/image.jpg",Server.MapPath("~/") +"photo/myFolder/image-resize.jpg",true);
File.Delete(Server.MapPath("~/") + "photo/myFolder/image.jpg");

I want to put in the string name into the code so i can create a folder named by the textbox input. How can I modify this code to do that?
string name = txtUsername.Text;
string path = Server.MapPath("~/here the string name /");
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
string path = Server.MapPath("~/" + name);
I have a string that defines the path of a file:
string duplicateFilePath = D:\User\Documents\processed\duplicate_files\file1.jpg;
I am going to move a file to this location but sometimes a file with the identical name exists all ready. In this case I want to differentiate the filename. I have the crc value of each file available so I figured that may be good to use to ensure individual file names. I can create:
string duplicateFilePathWithCrc = duplicateFilePath + "(" + crcValue + ")";
But this gives:
D:\User\Documents\processed\duplicate_files\file1.jpg(crcvalue);
and I need:
D:\User\Documents\processed\duplicate_files\file1(crcvalue).jpg;
How can I put the crcvalue into the string before the file extension, bearing in mind there could be other .'s in the file path and file extensions vary?
Use the static methods in the System.IO.Path class to split the filename and add a suffix before the extension.
string AddSuffix(string filename, string suffix)
{
string fDir = Path.GetDirectoryName(filename);
string fName = Path.GetFileNameWithoutExtension(filename);
string fExt = Path.GetExtension(filename);
return Path.Combine(fDir, String.Concat(fName, suffix, fExt));
}
string newFilename = AddSuffix(filename, String.Format("({0})", crcValue));
int value = 42;
var path = #"D:\User\Documents\processed\duplicate_files\file1.jpg";
var fileName = String.Format("{0}({1}){2}",
Path.GetFileNameWithoutExtension(path), value, Path.GetExtension(path));
var result = Path.Combine(Path.GetDirectoryName(path), fileName);
Result:
D:\User\Documents\processed\duplicate_files\file1(42).jpg
Something like this
string duplicateFilePath = #"D:\User\Documents\processed\duplicate_files\file1.jpg";
string crcValue = "ABCDEF";
string folder = Path.GetDirectoryName(duplicateFilePath);
string filename = Path.GetFileNameWithoutExtension(duplicateFilePath);
string extension = Path.GetExtension(duplicateFilePath);
string newFilename = String.Format("{0}({1}){2}", filename, crcValue, extension);
string path_with_crc = Path.Combine(folder,newFilename );
This can also be achieved by using Replace:
using System.IO;
string duplicateFilePathWithCrc = duplicateFilePath.Replace(
Path.GetFileNameWithoutExtension(duplicateFilePath),
Path.GetFileNameWithoutExtension(duplicateFilePath + "(" + crcValue + ")"),
);
Try using the Path class (it's in the System.IO namespace):
string duplicateFilePathWithCrc = Path.Combine(
Path.GetDirectoryName(duplicateFilePath),
string.Format(
"{0}({1}){2}",
Path.GetFileNameWithoutExtension(duplicateFilePath),
crcValue,
Path.GetExtension(duplicateFilePath)
)
);
Getting this error The given path's format is not supported. at this line
System.IO.Directory.CreateDirectory(visit_Path);
Where I am doing mistake in below code
void Create_VisitDateFolder()
{
this.pid = Convert.ToInt32(db.GetPatientID(cmbPatientName.SelectedItem.ToString()));
String strpath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
String path = strpath + "\\Patients\\Patient_" + pid + "\\";
string visitdate = db.GetPatient_visitDate(pid);
this.visitNo = db.GetPatientID_visitNo(pid);
string visit_Path = path +"visit_" + visitNo + "_" + visitdate+"\\";
bool IsVisitExist = System.IO.Directory.Exists(path);
bool IsVisitPath=System.IO.Directory.Exists(visit_Path);
if (!IsVisitExist)
{
System.IO.Directory.CreateDirectory(path);
}
if (!IsVisitPath)
{
System.IO.Directory.CreateDirectory(visit_Path);\\error here
}
}
getting this value for visit_Path
C:\Users\Monika\Documents\Visual Studio 2010\Projects\SonoRepo\SonoRepo\bin\Debug\Patients\Patient_16\visit_4_16-10-2013 00:00:00\
You can not have : in directory name, I suggest you to use this to string to get date in directory name:
DateTime.Now.ToString("yyyy-MM-dd hh_mm_ss");
it will create timestamp like:
2013-10-17 05_41_05
additional note:
use Path.Combine to make full path, like:
var path = Path.Combine(strpath , "Patients", "Patient_" + pid);
and last
string suffix = "visit_"+visitNo+"_" + visitdate;
var visit_Path = Path.Combine(path, suffix);
In general always use Path.Combine to create paths:
String strPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
String path = Path.Combine(strPath,"Patients","Patient_" + pid);
string visitdate = db.GetPatient_visitDate(pid);
this.visitNo = db.GetPatientID_visitNo(pid);
string fileName = string.Format("visit_{0}_{1}", visitNo, visitdate);
string visit_Path = Path.Combine(path, fileName);
bool IsVisitExist = System.IO.Directory.Exists(path);
bool IsVisitPath=System.IO.Directory.Exists(visit_Path);
To replace invalid characters from a filename you could use this loop:
string invalidChars = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars());
foreach (char c in invalidChars)
{
visit_Path = visit_Path.Replace(c.ToString(), ""); // or with "."
}
You can't have colons : in file paths
You can't use colons (:) in a path. You can for example Replace() them with dots (.).
Just wanted to add my two cents.
I assigned the path from a text box to string and also adding additional strings, but I forgot to add the .Text to the text box variable.
So instead of
strFinalPath = TextBox1.Text + strIntermediatePath + strFilename
I wrote
strFinalPath = TextBox1 + strIntermediatePath + strFilename
So the path became invalid because it contained invalid characters.
I was surprised that c# instead of rejecting the assignment because of type mismatch, assigned invalid value to the final string.
So look at the path assignment string closely.
How do I get the full path for a given file?
e.g. I provide:
string filename = #"test.txt";
Result should be:
Full File Path = C:\Windows\ABC\Test\test.txt
Try
string fileName = "test.txt";
FileInfo f = new FileInfo(fileName);
string fullname = f.FullName;
Use Path.GetFullPath():
http://msdn.microsoft.com/en-us/library/system.io.path.getfullpath.aspx
This should return the full path information.
You Can use:
string path = Path.GetFullPath(FileName);
it will return the Full path of that mentioned file.
Directory.GetCurrentDirectory
string dirpath = Directory.GetCurrentDirectory();
Prepend this dirpath to the filename to get the complete path.
As #Dan Puzey indicated in the comments, it would be better to use Path.Combine
Path.Combine(Directory.GetCurrentDirectory(), filename)
I know my answer it's too late, but it might helpful to other's
Try,
Void Main()
{
string filename = #"test.txt";
string filePath= AppDomain.CurrentDomain.BaseDirectory + filename ;
Console.WriteLine(filePath);
}
try..
Server.MapPath(FileUpload1.FileName);
try:
string fileName = #"test.txt";
string currentDirectory = Directory.GetCurrentDirectory();
string[] fullFilePath = Directory.GetFiles(currentDirectory, filename, SearchOption.AllDirectories);
it will return full path of all such files in the current directory and its sub directories to string array fullFilePath. If only one file exist it will be in "fullFileName[0]".
private const string BulkSetPriceFile = "test.txt";
...
var fullname = Path.GetFullPath(BulkSetPriceFile);
You can get the current path:
string AssemblyPath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location).ToString();
Good luck!
I am trying to copy all format file (.txt,.pdf,.doc ...) file from source folder to destination.
I have write code only for text file.
What should I do to copy all format files?
My code:
string fileName = "test.txt";
string sourcePath = #"E:\test222";
string targetPath = #"E:\TestFolder";
string sourceFile = System.IO.Path.Combine(sourcePath, fileName);
string destFile = System.IO.Path.Combine(targetPath, fileName);
Code to copy file:
System.IO.File.Copy(sourceFile, destFile, true);
Use Directory.GetFiles and loop the paths
string sourcePath = #"E:\test222";
string targetPath = #"E:\TestFolder";
foreach (var sourceFilePath in Directory.GetFiles(sourcePath))
{
string fileName = Path.GetFileName(sourceFilePath);
string destinationFilePath = Path.Combine(targetPath, fileName);
System.IO.File.Copy(sourceFilePath, destinationFilePath , true);
}
I kinda got the impression you wanted to filter by extension. If so, this will do it. Comment out the parts I indicate below if you don't.
string sourcePath = #"E:\test222";
string targetPath = #"E:\TestFolder";
var extensions = new[] {".txt", ".pdf", ".doc" }; // not sure if you really wanted to filter by extension or not, it kinda seemed like maybe you did. if not, comment this out
var files = (from file in Directory.EnumerateFiles(sourcePath)
where extensions.Contains(Path.GetExtension(file), StringComparer.InvariantCultureIgnoreCase) // comment this out if you don't want to filter extensions
select new
{
Source = file,
Destination = Path.Combine(targetPath, Path.GetFileName(file))
});
foreach(var file in files)
{
File.Copy(file.Source, file.Destination);
}
string[] filePaths = Directory.GetFiles(#"E:\test222\", "*", SearchOption.AllDirectories);
use this, and loop through all the files to copy into destination folder
