Combining URIs in C#

The best way to join URLs in C# code in ASP.NET is to use the System.Uri class. Here is a sample for joining URIs in C# code in controller of ASP.NET project.

public ActionResult Index()
    Uri bUri = new Uri("");
    Uri finalUri = new Uri(bUri, "/tools/cryptography");

    ViewBag.Uri = finalUri.ToString();

    return View();
