从字符串中删除文本,直到达到某个字符

Question

我正试图找出这个问题.我需要"修复"一些链接,这是一个例子:

1. www.site.com/link/index.php?REMOVETHISHERE
2. www.site.com/index.php?REMOVETHISHERE

所以基本上我想删除所有东西,直到它到达？字符.谢谢你的帮助.

Answer 1

 string s = @"www.site.com/link/index.php?REMOVETHISHERE";
 s = s.Remove( s.LastIndexOf('?') );
 //Now s will be simply "www.site.com/link/index.php"

应该这样做
