Question

In C# using visual studio 2010 .NET framework 4.0.

Every time I try to make a redirection using response.redirect("url") I get the following error:

System.NullReferenceException was unhandled by user code
  Message=Object reference not set to an instance of an object.
  Source=App_Web_uck3gvsb
  StackTrace:
       at _Default.Page_Load(Object sender, EventArgs e) in c:\inetpub\wwwroot\p1\Default.aspx.cs:line 15
       at System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e)
       at System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e)
       at System.Web.UI.Control.OnLoad(EventArgs e)
       at System.Web.UI.Control.LoadRecursive()
       at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
  InnerException: 

And here is the code: Even on simple without anything, I get the same error!

using System;
using System.Collections.Generic;

using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page
{
    public  HttpResponse response;
    protected void Page_Load(object sender, EventArgs e)
    {

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

Answer 1

You should be using:

Response.Redirect("www.bing.com");

not:

response.Redirect("...")
