Delete folder with C# code?

Question

I am trying to delete a folder but i can manage to get it right?

The folder i am trying to delete is called ExtractedFiles and it is inside a folder called FormValue.

I can delete a spreadsheet in the same FormValue folder but cant delete the folder.

I think the problem might be that i don't have the right file extension for the folder

This works:

if (File.Exists(tempFolderPathAlt + saveas + ".xls"))
            {
                File.Delete(tempFolderPathAlt + saveas + ".xls");
            }

This does not work:

 if (File.Exists(tempFolderPathAlt + "ExtractedFiles"))
            {
                File.Delete(tempFolderPathAlt + "ExtractedFiles");
            }

Could someone please tell me the file extension of a folder or how to delete one?

if you need to delete the Folder and all its content why don't you use Directory.Delete ? http://msdn.microsoft.com/en-us/library/fxeahc5f.aspx — Davide Piras, Oct 09 '12 at 10:02

If you want to delete a folder, you should use Directory.Delete instead of File.Delete:

String path = Path.Combine(tempFolderPathAlt, "ExtractedFiles");
bool directoryExists = Directory.Exists(path);
if(directoryExists)
    Directory.Delete(path, true); // deletes sub-directories

For deleting dirrectories, you need to use the method

Directory.Delete(string path,
    bool recursive);

Check this out if you are getting IOException deleting directories :

Cannot delete directory with Directory.Delete(path, true)
