How do I find difference between two dates? In C#

DateTime startDate = new DateTime(2005, 2, 1, 3, 4, 12, 56);
// End date
DateTime endDate = new DateTime(2005, 12, 12, 4, 30, 45, 12);
// Time span
TimeSpan diffDate = endDate.Subtract ( startDate );
// Spit it out
Response.Write( “Time Difference: “);
Response.Write(diffDate.Days.ToString() + ” Days ”);
Response.Write(diffDate.Hours.ToString() + ” Hours ” );
Response.Write(diffDate.Minutes.ToString() + ” Minutes ”);
Response.Write(diffDate.Seconds.ToString() + ” Seconds “);
Response.Write(diffDate.Milliseconds.ToString() + ” Milliseconds ”);
