c# - How do i remove a variable part of a string?

问题:

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.

回答1:

The regex to match that is /[^/]*/cms/, used like this: new Regex("/[^/]*/cms/").Replace(yourString, "")

回答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.

The accepted answer in this question will help you. Ensure that you use the Regex.Replace() method to do the pattern matching and replacement.

Look up Regex.Replace. Hacking the example quickly:

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