C#中Split用法

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>");
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

////////////////////////////////////////////////

string[] arr = str.Split("o");

这是一个具有语法错误的语句，Split 的 separator 参数应该是 char[] 或 string[]，不应是字符串。正确的示例：

string str = "technology";
char[] separator = { o };
string[] arr = str.Split(separator);

String.Split 方法有6个重载函数：

程序代码

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)

下边我们通过一些实例来说明下怎么使用(以下string words = "1,2.3,,4";)：
1. public string[] Split(params char[] separator)

程序代码

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个人空间,n:H!C0M/S3Uu0002P

程序代码

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)

程序代码

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)

程序代码

string[] split = words.Split(new string[] { ",", "." }, StringSplitOptions.RemoveEmptyEntries);//返回:{"1","2","3","4"} 不保留空元素
