How To Use Request.Querystring In SharePoint 2010 Application Page?

Question

I have the following lines of code:

SPList thisList = oWeb.Lists[new Guid(Request.Url.QueryString).Get("List")];
SPListItem thisItem = thisList.GetItemById(int.Parse(Request.QueryString["ID"]));

But the Request.Url.QueryString does not resolve correctly. I have included the following using statements:

using System;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
using System.Web;
using System.Reflection;
using Microsoft.SharePoint.Utilities;

When I right click I usually get a "Resolve" menu option if I have forgotten to put in a usings statement at the top but that does not appear.

How can I use Request to get the parameters passed into a SharePoint application page?

Answer 1

The answer is:

HttpContext.Current.Request.QueryString

Also make sure your page inherits from either LayoutPageBase or UnsecuredLayoutPageBase which are the base classes for application pages.
