What in Func in c#

    Func is a generic delegate that encapsulates a method that can accept parameters and return some value

//Annonymous function
Func MyFun1 = delegate(int[] a)
    {
        string tempString = "";
        foreach (int num in a) {
            tempString += num.ToString() + ",";
        }       
        return tempString;
    };



//Generic or Arrow function
    Func MyFun2 = (a) =>
    {
        string tempString = "";
        foreach (float num in a)
        {
            tempString += num.ToString() + ",";
        }
        return tempString;
    };

    private T[] Sort(T[] inputArray)
    {
        //Sort array
        //and return sorted array
        return inputArray;
    }

   int[] numArray = { 10, 15, 26, 98, 68 };
   float[] floatArray = { 10.9F, 15.5F, 26, 98.8F, 68 };
   lblMessage.Text = "Num : " + MyFun1.Invoke(Sort(numArray));
   lblMessage.Text += "Float : " + MyFun2.Invoke(Sort(floatArray));
