C# Determine if a file is being accessed

Just try this :

FileStream theFile = null;
try
{
    bool gotAccess = true;
    try {theFile = File.OpenFile(theFileName,  FileMode.Open, FileAccess.Read, FileShare.None);}
    catch (Exception) {gotAccess = false;}
    if (gotAccess)
   {
        // Here you've got exclusive access and you can perform the job.
   }
}
finally {if (theFile != null) {theFile.Close();}

What if what  I want to do is Delete the file? It has to be closed. And if I got access....I am presented with the same problem of making sure that the file is closed before I attempt a delete.

I can call Close on teh stream...but there is a period of time that must pass before the stream is actually closed and the file is released.

I am making a brute force file deleter. It is all too often that I want to delete a file that I do not need any more...but it is being accessed by another process. So, I tell the program to get all processes using that file...terminate them...and delete the file in question. However, there is a delay between the killing of the process, and the deletion of the file. I need to compensate for that. I would prefer that the program attempt to delete this file until it succeeds, or times out after a certain time.

Ok...got it. I just made a special delete method that returns false if it fails and true if it succeeds. That way  I can loop on it until it returns true.
