c# Split

标签：params   public   new   count   需要   vb.net   程序代码   函数   net   

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(‘,‘）
