Is there a way to distingish myFunc(1, 2, 3) from myFunc(new int[] { 1, 2, 3 })?

Question

A question to all of you C# wizards. I have a method, call it myFunc, and it takes variable length/type argument lists. The argument signature of myFunc itself is my

Answer 1

Yes, you can, checking the params length and checking the argument type, see the following working code sample:

class Program
{
    static void Main(string[] args)
    {
        myFunc(1, 2, 3);
        myFunc(new int[] { 1, 2, 3 });
    }

    static void myFunc(params object[] args)
    {
        if (args.Length == 1 && (args[0] is int[]))
        {
            // called using myFunc(new int[] { 1, 2, 3 });
        }
        else
        {
            //called using myFunc(1, 2, 3), or other
        }
    }
}
