enums are used to group a releated group of CONSTANTS. as they are constant, I do not think you can do that.

No it can't it can only have constants, nothing else

Maybe I misunderstood, but I think you need to pass enum items as parameters.
If so, any enum list can be translated into an integer value, representing it's index in the enum.

So, here is an example:

private enum List { firstItem, secondItem, otherItem };

private void Method(int enumParameter){
   // here you could check which enum item has been passed, using a switch like this:
   switch (enumParameter){
       case (int) List.firstItem:
                        // code
                        break;
        default:
                        break;
   }
}

So you just have to call the method this way:
this.Method((int)List.firstItem);

you can also do the following (using federicomarinucci's example as an example)  Not sure if all .net can do this, but i know C# can.

private enum List { firstItem, secondItem, otherItem }; 
private void Method(List enumParameter){
   switch (enumParameter){
       case List.firstItem:
                        // code
                        break;
       case List.secondItem:
                        // code
                        break;
        default:
                        break;
   }
} 
this.Method(List.firstItem);
