code snippet sets and gets the last write date and time of a file.
// Get and set file last write time
string fileName =
@"c:\temp\Mahesh.txt";
File.SetLastWriteTime(fileName,
DateTime.Now);
DateTime dt =
File.GetLastWriteTime(fileName);
Console.WriteLine("File
last write time: {0}", dt.ToString());
