您的要求不清楚。你想从服务器上的代码隐藏重定向吗？

 Response.Redirect（  http://www.google.com跨度>）; 

i want to open any url from search box simply typing url like https://www.codeproject.com/Questions/ask.aspx.
or
www.codeproject.com/Questions/ask.aspx

Kindly Help me in this. dont commnet i cant etc. solve my problem kindly.

What I have tried:

protected void Page_Load(object sender, EventArgs e)
        {
            WebRequest wReq = WebRequest.Create("http://www.google.com");
            WebRequest mRes = wReq.GetResponse();
            StreamReader sr = new StreamReader(mRes.GetResponseStream());
            string sHTML = sr.ReadToEnd();
            sr.Close();
            mRes.Close();
            if (sHTML != string.Empty && sHTML != null)
            {
                Literal1.Text = sHTML;

            }

Your requirements are unclear. Are you wanting to redirect from code-behind on server?

Response.Redirect("http://www.google.com");
