System.Collections.Generic.IEnumerable' does not contain any definition for 'ToList'

Question

Here is the problem. I am getting IEnumerable from ViewPage and when I tried it to convert List it is showing me error like:

\'System.Collection

Answer 1

You're missing a reference to System.Linq.

Add

using System.Linq

to get access to the ToList() function on the current code file.

To give a little bit of information over why this is necessary, Enumerable.ToList is an extension method. Extension methods are defined outside the original class that it targets. In this case, the extension method is defined on System.Linq namespace.
