Get list from enum

Question

public enum MyEnum
{
    A,
    Ab,
    Abc,
    Abcd,
    Abcde
}

Using LINQ, I want to extract a list from MyEnum that contains all the items of MyEnum except the items Ab and Abc.

The first google result gave me the answer already. Please show some effort next time. http://msdn.microsoft.com/en-us/library/system.enum.getvalues.aspx — Jeroen Vannevel, Sep 19 '13 at 20:35

Do you want a list of strings with the names or a list of MyEnums set to all the values? — Hogan, Sep 19 '13 at 20:39
@JeroenVannevel You did not understand my question body, I know about Enum.GetValues() but it's not what I'm asking. you should show more effort to analyze the questions instead of fast reacting — Stacked, Sep 19 '13 at 23:59
@Bob. Thanks for your comment but this is not what I'm asking. — Stacked, Sep 20 '13 at 00:09

var doNotUse = new[] { MyEnum.Ab, MyEnum.Abc };
var enums = Enum.GetValues(typeof(MyEnum)).Cast<MyEnum>()
    .Where(me => !doNotUse.Contains(me))
    .ToList();

var list = Enum.GetNames(typeof(MyEnum))
               .Where(r=> r != "Abc" && r != "Ab")
               .ToList();

For output:

foreach(var item in list)
    Console.WriteLine(item);

Output:

A
Abcd
Abcde

@KingKing, my bad, used `GetValues`, instead of GetNames. – Habib Sep 19 '13 at 20:38
Whats up with the downvotes ? – Habib Sep 19 '13 at 20:41
Whats up with the upvotes for `Enum.GetValues(typeof(MyEnum).Where(r=> r != "ABC").ToList()` ? – I4V Sep 19 '13 at 20:44
@I4V, I am surprised at this, I used `GetValues` which was wrong, corrected it and still getting downvotes. – Habib Sep 19 '13 at 20:50

you don't need linq :

    public void test()
    {
        List<MyEnum> list = new List<MyEnum>();

        foreach (MyEnum item in Enum.GetValues(typeof(MyEnum)))
        {
            list.Add(item);
        }
    }
