几种输出字符串的格式和字符分割

//用多个字符来分割
         string s = "mmmjnnsnnjbbb";
            string[] array=s.Split(new char[2]{'j','s'});
            foreach (string i in array)
            {
                Response.Write(i.ToString() + "<br>");
            }


            //用字符串来分割   首先添加引用  using System.Text.RegularExpressions;
            string s1 = "mmmjgnnnnnjgnssss";
            string[] array1 = Regex.Split(s1, "js", RegexOptions.IgnoreCase);
            foreach (string i in array1)
            {
                Response.Write(i.ToString() + "<br>");
            }

 

输出字符串的格式：

int s2 = 12345;
            s2.ToString("C");//生成￥12,345.00
            s2.ToString("n");//生成12，345.00
            s2.ToString("f4");//生成12345.0000;
            s2.ToString("p");//生成1，234，500.00%
