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

In case someone stumbles on this questions after googling...

I had the exact same problem in Razor views and adding using System.Linq at the top didn't help.

What did help is calling .Cast() before using Linq extension methods:

myArrayVariable.Cast().ToList() //ok, NOW ToList works fine
