c#字符串练习

  1，分出字符串

  

 protected void Button1_Click(object sender, EventArgs e)
        {
            //把一个字符串按|号分出来输出，但不输出掉空格
            string a = "a|b||||c||d";

            StringBuilder sb=new StringBuilder ();

            

            string[] ss = a.Split(new char[] { '|' }, StringSplitOptions.RemoveEmptyEntries);

          for (int i = 0; i < ss.Length; i++)
            {
               sb.Append(ss[i]);
            }

            Response.Write(sb);
        }
