Datatime的输出格式

DateTime类型:直接使用DateTime.ToString("格式")方法.
str = DateTime.Parse("2010-7-7").ToString("yyyy/MM/dd");

一般大家都是用上面的格式("yyyy/MM/dd");)来转换输出 xxxx-xx-xx的格式的字符串;

但是它们都是有缩写的 比如：

string a = "";  

           a = DateTime.Now.ToString("d");  Console.WriteLine("d:" + a);    

         a = DateTime.Now.ToString("D"); Console.WriteLine("D:" + a);  

           a = DateTime.Now.ToString("f");Console.WriteLine("f:" + a);   

          a = DateTime.Now.ToString("F");Console.WriteLine("F:" + a);

            a = DateTime.Now.ToString("g");Console.WriteLine("g:" + a);

            a = DateTime.Now.ToString("G");Console.WriteLine("G:" + a);            

            a = DateTime.Now.ToString("M");Console.WriteLine("M:" + a);    

         a = DateTime.Now.ToString("R"); Console.WriteLine("R:" + a);      

       a = DateTime.Now.ToString("s");Console.WriteLine("s:" + a);        

     a = DateTime.Now.ToString("t");  Console.WriteLine("t:" + a);          

   a = DateTime.Now.ToString("T"); Console.WriteLine("T:" + a);        

     a = DateTime.Now.ToString("u");Console.WriteLine("u:" + a);      

       a = DateTime.Now.ToString("U"); Console.WriteLine("U:" + a);  

           a = DateTime.Now.ToString("Y");Console.WriteLine("Y:"+a);

下面是输出结果如图：
