c#日期到字符串转换

      在编程中经常要用到将日期变量转换为字符串的情况,而且不同的时候希望
转换成不同格式的字符串
       下面是一些常用的转换及转换结果:
       

private void Form1_Load(object sender, System.EventArgs e)
  {
   //textBox1.Text=DateTime.Now.ToString("dd/MM/yyyy");
//textBox1.Text=DateTime.Now.DayOfYear.ToString();
   textBox1.Text=DateTime.Now.ToString("d");
   textBox2.Text=DateTime.Now.ToString("D");
   textBox3.Text=DateTime.Now.ToString("G");
   textBox6.Text=DateTime.Now.ToString("g");
   textBox5.Text=DateTime.Now.ToString("T");
   textBox4.Text=DateTime.Now.ToString("t");

   textBox12.Text=DateTime.Now.ToString("F");
   textBox11.Text=DateTime.Now.ToString("f");
   textBox10.Text=DateTime.Now.ToString("M");
   textBox9.Text=DateTime.Now.ToString("R");
   textBox8.Text=DateTime.Now.ToString("s");
   textBox7.Text=DateTime.Now.ToString("u");

   textBox13.Text=DateTime.Now.ToString("Y");
   textBox14.Text=DateTime.Now.ToString("y");

  }



      下面是另外的方法转换的结果:
      

private void Form2_Load(object sender, System.EventArgs e)
  {
   textBox1.Text=DateTime.Now.ToString("M/d/yyyy");
   textBox2.Text=DateTime.Now.ToString("MM/dd/yy");
   textBox3.Text=DateTime.Now.ToString("d-MMMM-yy");
   textBox6.Text=DateTime.Now.ToString("ddMMyyyy");
   textBox5.Text=DateTime.Now.ToString("dd日MM月yyyy年");
   textBox4.Text=DateTime.Now.ToString("yyyy年MM月dd日");

   textBox12.Text=DateTime.Now.ToString("yyyy年");
   textBox11.Text=DateTime.Now.ToString("MM月");
   textBox10.Text=DateTime.Now.ToString("dd日");
   textBox9.Text=DateTime.Now.ToString("hh:mm:ss");
   textBox8.Text=DateTime.Now.ToString("M/d/yyyy H:mm");
   textBox7.Text=DateTime.Now.ToString("H:mm:ss")

;
  }
