Converting an Enum to a list

Question

I have an enum defined as

public enum SecurityRole
{
    Admin = 0,
    ViewLog = 1,
    DeleteLog = 2
}

and want to use the technique described here to get a List<SecurityRole>.

Thus the line

var lst = Enum.GetValues(typeof(SecurityRole)).Cast<SecurityRole>().ToList();

should work, but IntelliSense wont allow the .ToList property

I am using System.Linq. Is there some other reference I need?

Your code is valid, and executes successfully. As a shot in the dark, maybe Visual Studio is confused? Are there compilation errors, or just IntelliSense failures? Try relaunching VS. — Michael Petrotta, Mar 17 '13 at 06:45
@kirsten it works for me and this is the correct syntax, see the official question on this topic: http://stackoverflow.com/questions/1167361/how-do-i-convert-an-enum-to-a-list-in-c - Can you delete the `.` before `ToList()` and press the `.` if that fails press Ctrl+Space to bring up intellisense — Jeremy Thompson, Mar 17 '13 at 07:07
just try to rebuild the solution and try again because ur code should work since you use: `using System.Linq` — Ahmed Magdy, Mar 17 '13 at 07:43

using System.Linq should do it. ToList() is an IEnumerable<T> extension method. Probably check if you have any other compilation errors in your code.

`Cast` is also defined in `Enumerable` class – Sergey Berezovskiy Mar 17 '13 at 07:05
There were compiler errors. It works now they have been resolved. – Kirsten Mar 17 '13 at 09:10

Check the solution here: How do I convert an enum to a list in C#?

Enum.GetValues(typeof(SomeEnum)).Cast<SomeEnum>();

That will return an `IEnumerable`. To return a `List`, answers there recommend calling `ToList()`, just as the OP here has done. – Michael Petrotta Mar 17 '13 at 06:51
