Why can't I use ToList() with my KeyCollection
.net, c#, dictionary
Solution
This is fixed by adding a
using System.Linq;
to the top of the .cs file.

Problem
I'm trying to modify each value in a Dictionary. The answers about how to do that generally look like this (taken from here): ``` foreach (var key in myDictionary.Keys.ToList()) { myDictionary[key] = <some kind of new value> } ``` Seemingly straightforward, but it doesn't work for me; Visual Studio underlines ToList() and says 'System.Web.UI.WebControls.QueryableDataSourceHelper.ToList(System.Linq.IQueryable, System.Type)' is inaccessible due to its protection level. Am I doing something wrong? (Obviously yes, but what?)
