UUEncode.Decode deleting file after failed decode

Question

I am using UUEncode.Decode to decode a batch of UUEncoded files. Occasionally one of the UUEncoded files is corrupt, causing UUEncode.Decode to terminate. I handle this with Try .. Catch .. End Try, which successfully handles the failure to decode a particular UUEncoded file.

For the next step I need to delete the UUEncoded file. If the UUEncode.Decode was successful then I can go on to delete the UUEncoded file, but if the UUEncode.Decode failed, causing a catch, then I cannot delete the file as it is still open.

Any idea how to close the file left open by UUEncode.Decode so that I can proceed to delete it?

Here is the code:

Try

strOutputFilename = UUEncode.Decode(lblWorkingPath.Text & strFilename & ".uu", lblWorkingPath.Text)

Catch ex As Exception

strOutputFilename = ""

End Try


File.Delete(lblWorkingPath.Text & strFilename & ".uu")
