时间变量转换到字符串变量

 using System; using System.Globalization;  public class MainClass {     public static void Main(string[] args)  {        DateTime dt = new DateTime(2000, 8, 17, 16, 32, 32);

        String[] format = {            "d", "D",            "f", "F",            "g", "G",            "m",            "r",            "s",            "t", "T",            "u", "U",            "y",            "dddd, MMMM dd yyyy",            "ddd, MMM d /"'/"yy",            "dddd, MMMM dd",            "M/yy",            "dd-MM-yy",        };        String date;        for (int i = 0; i < format.Length; i++) {            date = dt.ToString(format[i], DateTimeFormatInfo.InvariantInfo);            Console.WriteLine(String.Concat(format[i], " :" , date));        }     /** Output.    *    * d :08/17/2000    * D :Thursday, August 17, 2000    * f :Thursday, August 17, 2000 16:32    * F :Thursday, August 17, 2000 16:32:32    * g :08/17/2000 16:32    * G :08/17/2000 16:32:32    * m :August 17    * r :Thu, 17 Aug 2000 23:32:32 GMT    * s :2000-08-17T16:32:32    * t :16:32    * T :16:32:32    * u :2000-08-17 23:32:32Z    * U :Thursday, August 17, 2000 23:32:32    * y :August, 2000    * dddd, MMMM dd yyyy :Thursday, August 17 2000    * ddd, MMM d "'"yy :Thu, Aug 17 '00    * dddd, MMMM dd :Thursday, August 17    * M/yy :8/00    * dd-MM-yy :17-08-00    */    }}

字符串转化为时间

string s = "2008-11-07 08:55:32";

DateTime t = Convert.ToDateTime(s);

时间间隔类

DateTime t1= new DateTime(2000, 8, 17, 16, 32, 32);

DateTime t2= new DateTime(2000, 9, 22, 33, 44, 55);

TimeSpan ts = t2 - t1;
