How to pass multiple parameters to user defined function in excel

Hi Experts,

I am working on an Excel add-in and want to pass multiple parameter to a function which i defined.

for example if i send the parameters as follows it doesn't work.

  public int AddNumbers(params int[] Numbers)
        {
            int Result = 0;
            for (int i = 0; i < Numbers.Length; i++)
            {
                if (i==0)
                {
                    Result = Numbers[i];
                }
                else
                {
                   Result = Numbers[i - 1] + Numbers[i];
                }
               
            }
            return Result;
        }

but if i use the function as follows it works,

        public int Addtest(int a, int b){

            int test = 0;
            try
            {
                test = AddNumbers(new int[] {a,b });
            }
            catch (Exception)
            {
               
                throw;
            }
            return test;
        }

My question is, I have a user defined function in my excel add-in project  and want to pass last parameters as a parameter array not as an optional range.

public object DummyFunction(string strDummy1, string strDummy2, object objDummy, params string[] strInputs)

I don't think it's possible to pass arrays into Excel functions.

You will need to make this a Range, which is effectively the same thing except it has the potential to have incorrect data types - so you'll need to filter those.
