I have a problem with the function Directory.delete?

Take a look at my code:

strin开发者_JAVA技巧g desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        try
        {
            if (Directory.Exists(Path.Combine(desktopPath, "Hackers.avi")))
                Directory.Delete(Path.Combine(desktopPath, "Hackers.avi"), true);

after runing the file is still exist on my desktop , why??

It is unlikely that Hackers.avi is a directory - .avi is normally used an extension for a video file (see Audio Video Interleave on Wikipedia for more information).

Try using File.Delete instead of Directory.Delete:

string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
try
{
    string pathToFile = Path.Combine(desktopPath, "Hackers.avi");
    File.Delete(pathToFile);
    // etc...

I also omitted the call to File.Exists because you don't have to check for a file's existence before deleting it. File.Delete does not throw if the file doesn't exist.

You want to delete file, sou you must use 'File.Delete'
