Delete specific files in directory using C#

Question

There are many .bmp files present in my C:\TEMP directory.

I am using following code to delete all .bmp file in my C:\TEMP directory but somehow its not working as I expect. Can anyone help me in this?

string[] filePaths = Directory.GetFiles(@"c:\TEMP\"); foreach (string filePath in filePaths) { if (filePath.Contains(".bmp")) File.Delete(filePath); }

I have already checked that .bmp file and the directory has no read only attribute

Tip: Use the searchPattern argument in Directory.GetFiles to only get bitmaps. (e.g. "*.bmp") See MSDN article — AndrewL

Are you running app manually under your user account, do you have access to delete files from C:\Temp? Also, are any of the files in use when your trying to delete them. What type of results / errors are you seeing when you try to delete the files ? — Zachary

For starters, GetFiles has an overload which takes a search pattern http://msdn.microsoft.com/en-us/library/wz42302f.aspx so you can do:

Directory.GetFiles(@"C:\TEMP\", "*.bmp");

Edit: For the case of deleting all .bmp files in TEMP:

string[] filePaths = Directory.GetFiles(@"c:\TEMP\", "*.bmp"); foreach (string filePath in filePaths) { File.Delete(filePath); }

This deletes all .bmp files in the folder but does not access subfolders.

Should also use .EndsWith instead of .Contains

You Could write below code in fast way:

 string[] t = Directory.GetFiles(Environment.CurrentDirectory, "*.pdf"); Array.ForEach(t, File.Delete);

or For Text Files:

 string[] t = Directory.GetFiles(Environment.CurrentDirectory, "*.txt"); Array.ForEach(t, File.Delete);

So, You could write code for all extension and all directories.
