C# in VS2005: can you check whether an integer is delcared in a given Enum type?

Question

For C# in VS2005, is there way to check if an integer is part of a Enum type?

eg:

if number in CustomerType { ... }

where

enum CustomerType
{
    A = 0;
    B = 1;
    C = 2;
}

Answer 1

Is Enum.IsDefined(Type enumType, Object value) what you're looking for?

Instead of your if-statement:

if (Enum.IsDefined(typeof(CustomerType), number))
{
    ...
}

Answer 2

Try something like this:

var value = Enum.GetName(typeof(CustomerType), 3); // instead of 3 you can use any value

where CustomerType is:

public enum CustomerType
{
    A = 0,
    B = 1,
    C = 2,
}

By passing 3 value will have a null value. If you pass an existing value (i.e. 0, 1 or 2) then you'll get "A", "B" or "C".

For further info you can check the static methods of the System.Enum class.
