相对〜绝对URL路径的一般解决方案？

Question

I have a from some request. And I've got .

var uri = new Uri("http://www.contoso.com/");
var relativeUrl = "~/Pages/SomePage.aspx";

How do I combine the two easily?

What's the context, you may ask? It's a console application where the Uri and the tilde relative path are manually constructed (that's actually a lie to get a "General solution", and not an Page.Resolve, etc. one).

I tried a few things (IE: HttpStyleUriParser) but I didn't get the right result. And I don't want to String.Format("{0}://{1}{2}{3}") my way there.

Answer 1

The tilde character ~ is used in *nix systems for home directory of currect user .

In a .Net/C#/Windows application you must replace it by current user's home directory.

Answer 2

This works for me:

static class Program
{
    static void Main(string[] args)
    {

        var uri = new Uri("http://www.contoso.com/");
        var relativeUrl = new Uri("~/Pages/SomePage.aspx".Replace("~",string.Empty),UriKind.Relative);
        Uri result;
        bool success = Uri.TryCreate(uri, relativeUrl,out result);

        Console.WriteLine(success);
        Console.WriteLine(result.ToString());
    }

}

Output:

True
