foreach loop and "Object reference not set to an instance of an object"

I am using this code:

SetContentView (Resource.Layout.Results);
// Create your application here
string[] listResults = Intent.GetStringArrayExtra ("resultData");
LinearLayout linear = FindViewById<LinearLayout> (Resource.Id.linear);
TextView resultsPaste = FindViewById<TextView> (Resource.Id.resultsPaste);

foreach(string item in listResults) {
    resultsPaste.Text += item;
};

And I am receiving Object reference not set to an instance of an object next to the foreach. I have researched and can't find anything on it.

Why am I receiving the error?

listResults, resultsPaste or both are null. Put a breakpoint before foreach and check the variables.
