how to get current domain name in asp.net

In this blog I share my snippets code which can get your current domain name using C# in asp.net

We have three ways to complete this task

using System;
using System.Collections.Specialized;
using System.Web;
 
public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        // 1st
        Response.Write(Request.Url.Scheme + Uri.SchemeDelimiter + Request.Url.Host + (Request.Url.Port != 80 ? ":" + Request.Url.Port : ""));
        Response.Write("</br>");
        NameValueCollection variables = HttpContext.Current.Request.ServerVariables;
        string protocol = (variables["SERVER_PORT_SECURE"] == "1") ? "https://" : "http://"; string domain = variables["SERVER_NAME"];
        string port = variables["SERVER_PORT"];
        // 2nd
        Response.Write(protocol + domain + port);
        Response.Write("</br>");
        // 3rd
        string url = HttpContext.Current.Request.Url.AbsoluteUri.Replace(HttpContext.Current.Request.Url.AbsolutePath, "");
        Response.Write(url);
    }
}

Hope this help!
