1、用字符串分隔：
using System.Text.RegularExpressions;
string str="aaajsbbbjsccc";
string[] sArray=Regex.Split(str,"js",RegexOptions.IgnoreCase);
foreach (string i in sArray) Response.Write(i.ToString() + "<br>");
輸出結果：
aaa
bbb
ccc
2、用多個字符來分隔：
string str="aaajbbbscccjdddseee";
string[] sArray=str.Split(new char[2] {j,s});
foreach(string i in sArray) Response.Write(i.ToString() + "<br>");
輸出結果：
aaa
bbb
ccc
ddd
eee
3、用單個字符來分隔：
string str="aaajbbbjccc";
string[] sArray=str.Split(j);
foreach(string i in sArray) Response.Write(i.ToString() + "<br>");
輸出結果：
aaa
bbb
ccc
////////////////////////////////////////////////
string[] arr = str.Split("o");
這是一個具有語法錯誤的語句，Split 的 separator 參數應該是 char[] 或 string[]，不應是字符串。正確的示例：
string str = "technology";
char[] separator = { o };
string[] arr = str.Split(separator);
////////////////////////////////////////////////////
String.Split 方法有6個重載函數：
程序代碼
1) public string[] Split(params char[] separator)
2) public string[] Split(char[] separator, int count)
3) public string[] Split(char[] separator, StringSplitOptions options)
4) public string[] Split(string[] separator, StringSplitOptions options)
5) public string[] Split(char[] separator, int count, StringSplitOptions options)
6) public string[] Split(string[] separator, int count, StringSplitOptions options)
下邊我們通過一些實例來說明下怎麼使用(以下string words = "1,2.3,,4";)：
1. public string[] Split(params char[] separator)
程序代碼
string[] split = words.Split(new Char[] { , });//返回:{"1","2.3","","4"}
string[] split = words.Split(new Char[] { ,, . });//返回:{"1","2","3","","4"}
2. public string[] Split(char[] separator, int count)ITPUB個人空間,n:H!C0M/S3Uu0002P
程序代碼
string[] split = words.Split(new Char[] { ,, . }, 2);//返回:{"1","2.3,,4"}
string[] split = words.Split(new Char[] { ,, . }, 6);//返回:{"1","2","3","","4"}
3. public string[] Split(char[] separator, StringSplitOptions options)
程序代碼
string[] split = words.Split(new Char[] { ,, . }, StringSplitOptions.RemoveEmptyEntries);//返回:{"1","2","3","4"} 不保留空元素
string[] split = words.Split(new Char[] { ,, . }, StringSplitOptions.None);//返回:{"1","2","3","","4"} 保留空元素
4. public string[] Split(string[] separator, StringSplitOptions options)
程序代碼
string[] split = words.Split(new string[] { ",", "." }, StringSplitOptions.RemoveEmptyEntries);//返回:{"1","2","3","4"} 不保留空元素
u0002w1I+Ch%^u0017}0string[] split = words.Split(new string[] { ",", "." }, StringSplitOptions.None);//返回:{"1","2",&q
