Hi All,

I am copying my files to temp folder for quick access. For that i am using this code.

C#

if (File.Exists(tempAudpath))
{
    File.Delete(tempAudpath);
    File.Copy(Audpath, tempAudpath, true);
}
else
{
    File.Copy(Audpath, tempAudpath, true);
}

But delete is not happening. It is showing that another process is using.
Can any one help me to delete and copy files in this scenario.

Since the exception is showing "File in use by another process", it is not that you are trying to delete a directory - which File.Delete can't do. That was my initial thought when I saw your file names.

Without seeing the rest of your code - and I don't want you to post it all - I can't be too specific, but...

Since the name implies that this is a temporary file, I can only assume that your application has just written it? In which case, it is not quite as simple a fix as you think - the problem is not in this code fragment.
What has happened is that your code to write the file is not clean enough - you have not disposes all the objects which access the file. Since one or more objects have not been disposed, they still have what are called File Handles attached to the file. Since these exist, the system assumes (quite rightly) that the file is in use, and will not let you delete it.

Look at the other code which uses your temporary file, and Dispose (or preferably surround with a using block all the objects (streams, binaryWriters, textWriters, etc.) which access it.
