How do i keep the path in Uri decoded?

Question

I am trying to create a uri, but for some reason is the path being decoded everytime, causing problems with my browser trying to access the page the uri build?

POC:

using System;
                    
public class Program
{
    public static void Main()
    {
        Console.WriteLine("Hello World");
        var newLocation = new UriBuilder()
        {
            Scheme = Uri.UriSchemeHttps,
            Host = "localhost",
            Path = "/WebResource.axd?d=0"
        }.Uri;
        
        Console.WriteLine($"Hello World {newLocation}");
    }
}

This outputs:

Hello World
Hello World https://localhost/WebResource.axd%3Fd=0

I would have expected:

Hello World
Hello World https://localhost/WebResource.axd?d=0

Answer 1

Perhaps it is converting the question mark because you specified the question mark in the .path instead of in the .query. Try moving the ?d=0 into the .query and see if you get the same results.

Or, try loading the full URL into the UriBuilder using this overload like in the MS documentation: UriBuilder baseUri = new UriBuilder("http://www.contoso.com/default.aspx?Param1=7890");

I’m no expert, but it looks like it’s trying to replace the question mark, with it’s ASCII code, or 3F(%3F). This is probably because the question mark means a query in the browser, and is not considered part of the URI. Just a guess, I don’t know how I would fix it.

Hope I could help!
