    you can try this :
     
    1. static void Main(string[] args)  
    2.        {  
    3.            List<int> numbers = new List<int>();  
    4.            int result = Sum(numbers);  
    5.        } 
     
    1. public static int Sum(List<int> numbers)  
    2.        {  
    3.            numbers.Add(3);  
    4.            numbers.Add(2);  
    5.            numbers.Add(6);  
    6.            numbers.Add(-1);

    Hi Mngaro ,
    You no need to pass List in parameter, you can write method like below,
     
    And you can call methiod like this,
    int result = Sum();
    1. public static int Sum()  
    2.         {  
    3.             List<int> numbers = new List<int>();  
    4.             numbers.Add(3);  
    5.             numbers.Add(2);  
    6.             numbers.Add(6);  
    7.             numbers.Add(-1);  
    8.             numbers.Add(5); numbers.Add(1);  
    9.             return numbers.Sum();  
    10.         }
