调试易

ToString("r");
或者：ToString("ddd,d MMM yyyy HH:mm:ss")

System.Globalization.CultureInfo info =
            new System.Globalization.CultureInfo("en-US", false);
       
         System.Globalization.Calendar calendar = info.Calendar;
            
         System.DateTime dateTime = 
            new System.DateTime(1979,      // Year
                           07,         // Month
                           28,         // Day
                           22,         // Hour
                           35,         // Minute
                           5,         // Second
                           15,         // Millisecond
                           calendar   // Calendar
                           );           // Write the DateTime as "Saturday, July 28, 1979 10:35:05 PM".
         System.Console.WriteLine("{0:F}", dateTime);

来晚了。
System.DateTime.Now.ToString("r");
System.DateTime.Now.ToString("ddd,d MMM yyyy HH:mm:ss")如colinfly(Colin) 所说
