我如何删除字符串的可变部分？

Question

I would like to remove part of a string. It would have to match "/*/cms/" (without the quotes). * would be a wildcard equaling anything except a / key. The string could have more than one match to be removed.

This would have to be done in c#. I think this can be done with a regex? But I'm not sure.

Answer 1

要匹配的正则表达式是/[^/]*/cms/ ，使用方式如下： new Regex("/[^/]*/cms/").Replace(yourString, "")

Answer 2

using System.Text.RegularExpressions;

Regex.Replace("/some example text/cms/;/some more text/cms/text/cms", "/[^/]+/cms/", "")

Use /[^/]+/cms/ if something must be between the first and second / 's, use /[^/]*/cms/ if //cms/ is a valid match.

Answer 3

Look up Regex.Replace . Hacking the example quickly:

string pattern = "/[^/]+/cms/";
string replacement = "";
Regex rgx = new Regex(pattern);
string result = rgx.Replace(input, replacement);
