I want my program to move files from source folder to destination folder, but I get IO exception sometimes when the file is being accessed by another program. So, I want my program to make 5 tries if it encounter IO Exception with a gap of 1 min. how would I do that? It sound simple, but I am confused on how I would loop the try catch block max 5 times and come out of it if it was successful in less then 5 attempts.
Move_The_Files(ActiveWorkFolder + SubDirName, DestinationPath + SubDirName);

Perhaps something like this:
for (int i = 0; i < 5; i++)
{
    try
    {
        Move_The_Files(ActiveWorkFolder + SubDirName, DestinationPath + SubDirName);
        break;
    }
    catch (IOException ex)
    {
        Console.WriteLine(ex.ToString());
    }
}

public void MoveFile( string fromFileName, string toFileName, int numberOfRetries )
        {
            int numberOfSecondsBetweenRetries = 60;
            int retries = 0;

            while ( retries < numberOfRetries )
            {
                if ( moveFile( fromFileName, toFileName ) )
                {
                    retries = numberOfRetries;
                }
                else
                {
                    System.Threading.Thread.Sleep( numberOfSecondsBetweenRetries * 1000 );
                    retries++;
                }
            }
        }

        private bool moveFile( string fromFileName, string toFileName )
        {
            bool didSucceed = false;

            try
            {
                System.IO.File.Move( fromFileName, toFileName );
                didSucceed = true;
            }
            catch ( System.IO.IOException ioEx )
            {
                // do something with ioEx perhaps
                didSucceed = false;
            }
            catch ( Exception ex )
            {
                // Do somthing with ex perhaps
            }

            return didSucceed;
        }
