C# enums as function parameters?

Question

Can you pass a standard c# enum as a parameter?

For example:

enum e1
{
    //...
}

enum e2
{
    //...
}

public void test()
{
    myFunc( e1 );
    myFunc( e2 );
}

public void myFunc( Enum e )
{
    // Iterate through all the values in e
}

By doing this I hope to retrieve all the names within any given enum. What would the Iteration code look like?

Answer 1

This!

        public void Foo(Enum e)
        {
            var names = Enum.GetNames(e.GetType());

            foreach (var name in names)
            {
                // do something!
            }
        }   

EDIT: My bad, you did say iterate.

Note: I know I could just do the GetNames() call in my foreach statement, but I prefer to assign that type of thing to a method call first, as it's handy for debugging.

Use the Enum.GetNames( typeof(e) ) method, this will return an array of strings with the names.

You can also use Enum.GetValues to obtain the counterpart values.

Edit -Whoops - if you are passing the parameter as Enum, you will need to use e.GetType() instead of typeof() which you would use if you had passed the parameter in as the actual Enum type name.
