int endIndex =str.IndexOf("e");
string toStr = str.SubString(indexStart,endIndex-indexStart);

1、最简单最常用的方法，以一个指定的字符进行的分割
string s="abcdeabcdeabcde";
string[] sArray=s.Split('c');
foreach(string i in sArray)
Console.WriteLine(i.ToString());
输出下面的结果:abdeabdeabde
2、使用多个字符进行分割
string s="abcdeabcdeabcde"
string[] sArray1=s.Split(new char[3]{'c','d','e'});
foreach(string i in sArray1)
Console.WriteLine(i.ToString());
输出下面的结果：ababab
3、使用正则表达式添加引用 using System.Text.RegularExpressions;
string content="agcsmallmacsmallgggsmallytx";
string[]resultString=Regex.Split(content,"small",RegexOptions.IgnoreCase)
foreach(string i in resultString)
输出下面的结果:agcmacgggytx
