Possible NullreferenceException

c#, nullreferenceexception, resharper

Solution

I assume the checker isn't checking the value of the string passed to the CookieCollection indexer is the same each time. I imagine if you restructure the code to:

if (Request != null && Request.Cookies != null) 
{
    var place = Request.Cookies["place"];
    if (place != null && place.Value == null) 
    { 
        string placeInformation = place.Value;
    } 
}

It might work.

Problem

Resharper is showing a "Possible System.NullReferenceException" warning. I however can't see how I can get one. ``` public class PlaceController : PlanningControllerBase { [Authorize] public ActionResult StartStop(int id) { if (Request != null && Request.Cookies != null && Request.Cookies["place"] != null) { if (Request.Cookies["place"].Value != null)//Possible NullReferenceException? { string placeInformation = Request.Cookies["place"].Value;//Possible NullReferenceException? //... } } } } ``` How can this give a NullReference if I check all fields? Using the following doesn't show the warning: ``` Request.Cookies[0];//Index instead of name ``` Edit: updated code.
