用字符串分割

1 using System.Text.RegularExpressions;
2 string str="aaajsbbbjsccc";
3 string[] sArray=Regex.Split(str,"js",RegexOptions.IgnoreCase); //分割结果为aaa bbb ccc

 用多个字符串分割

1 string str="aaajbbbscccjdddseee";
2 string[] sArray=str.Split(new char[2]{'j','s'}); //分割结果为aaa bbb ccc ddd eee

 用单字符分割

1 string str="aaajbbbjccc";
2 string[] sArray=str.Split('j'); //分割结果为 aaa bbb ccc
