How to escape sharp(#) symbol in path?

I'm trying to get absolute path from string. Everything worked fine before i met path that contains sparp(#) symbol.
Here is my example:

class Program
    {
        static void Main(string[] args)
        {
            var codeBase = "file:///C:/#MyFolder/TestApp/bin/Debug/net6.0-windows/TestApp.dll";
            var uri = new Uri(codeBase);
            var path = Uri.UnescapeDataString(uri.AbsolutePath);
            Console.WriteLine(path);
        }
    }

And Uri.AbsolutePath returns C:\. Yeah Uri.AbsolutePath doesn't work with # symbol. But what sould i do in this case to get absolute path?
Honestly it's the first time i see that someone use this symbol in folder name.

For Uri you can use the %23 to escape the reserved # symbol:

var codeBase = "file:///C:/%23MyFolder/TestApp/bin/Debug/net6.0-windows/TestApp.dll";

You can try some thing like this:

var codeBase = "file:///C:/#MyFolder/TestApp/bin/Debug/net6.0-windows/TestApp.dll";
    var uri = new Uri(codeBase);
    var path = Uri.UnescapeDataString(uri.AbsolutePath);
    Console.WriteLine(path);

The Uri will work for you

#FolderName is the replacement to the folder in your pc.
