Jeff a οΏ½crit :

There's no direct way to achieve this cause c# doesn't have "set".
But if you're often using such a code you can just create a little
function :
public bool IsInSet(object source,object[] theSet)
{
foreach (object o in theSet)
if (o.Equals(source)) return true;
return false;
}
and you can use it this way :
if (IsInSet("foo",new object[] {1,2,3} ) ) Console.WriteLine("In set");
else Console.WriteLine("Not in set");
Console.ReadLine();
this sample will write "not in set" on the console since "foo" is not a
part of the set. If you change "foo" to 1, 2 or 3, the message will
become "In set".
Very simple.
