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() + "
");
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() + "
");
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() + "
");
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) 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
string[] split = words.Split(new string[] { ",", "." }, StringSplitOptions.None);//返回:{"1","2","3","","4"} 保留空元素
5. public string[] Split(char[] separator, int count, StringSplitOptions options) 程序代码 string[] split = words.Split(new Char[] { ',', '.' }, 2, StringSplitOptions.RemoveEmptyEntries);//返回:{"1","2.3,,4"} 不保留空元素
string[] split = words.Split(new Char[] { ',', '.' }, 6, StringSplitOptions.None);//返回:{"1","2","3","","4"} 保留空元素
6. public string[] Split(string[] separator, int count, StringSplitOptions options) 程序代码 string[] split = words.Split(new string[] { ",", "." }, 2, StringSplitOptions.RemoveEmptyEntries);//返回:{"1","2.3,,4"} 不保留空元素
string[] split = words.Split(new string[] { ",", "." }, 6, StringSplitOptions.None);//返回:{"1","2","3","","4"} 保留空元素 需要注意的是没有重载函数public string[] Split(string[] separator),所以我们不能像VB.NET那样使用words.Split(","),而只能使用words.Split(',')
