System.Array. does not contain a definition for “ToList”

Question

I\'m getting the above error on the ToList() line of the code below

if (emailReplyTo != null)
{
  System.Collections.Generic.List replyto
    = ema         


        

Answer 1

The ToList method you are looking for is an extension method. Try adding this using directive to the top of your file:

using System.Linq;

By adding this using directive you are indicating to the compiler that any extension methods in that namespace should be imported. It's kind of a shame that there isn't more help from Visual Studio around importing extension methods (ReSharper does this rather nicely).
