Question

Due to a restriction with a URLRewrite module, I am replacing all whitespace in a querystring value with hyphens.
Server side I want to replace the hyphens back to whitespace, which is fine.

However, if there is a hyphen in the querystring (before I encode the value), when I decode the querystring, it removes ALL hyphens, include the one which is meant to be there.

So my question is, how do I achieve the following with a Regex/Regex in C#….

Example 1
……………………………
Querystring: “a-search-term”
Decoded value: “a search term”

Example 2
……………………………
Querystring: “a-hyphenated—search”
Decoded value: “a hyphenated – search”

Also, I’m open for suggestions as to how to handle something like…

Querystring: “up-for–discussion”
Decoded value: “up for -discussion”

Many thanks

Could you do a simple string replace?

This should work for your basic scenarios but it’s not the best solution:

string newstring = yourstring.Replace("-", " ").Replace("   ", " - ").Replace("  ", " -");
