//using System.Text.RegularExpressions; //1、用字符串分隔: string str = "aaajsbbbjsccc"; string[] sArray = Regex.Split(str, "js", RegexOptions.IgnoreCase); foreach (string i in sArray) Response.Write(i.ToString() + "<br>"); //输出结果: //aaa //bbb //ccc //2、用多个字符来分隔: string str = "aaajbbbscccjdddseee"; string[] sArray = str.Split(new char[2] { 'j', 's' }); foreach (string i in sArray) Response.Write(i.ToString() + "<br>"); //输出结果: //aaa //bbb //ccc //ddd //eee //3、用单个字符来分隔: string str = "aaajbbbjccc"; string[] sArray = str.Split('j'); foreach (string i in sArray) Response.Write(i.ToString() + "<br>"); //输出结果: //aaa //bbb //ccc
