这个项目用C#怎么做出来呀

        public int Max(int[] nums)
        {
            int result = nums[0];
            for (int i = 0; i < nums.Length; i++)
            {
                if (nums[i] >= result)
                    result = nums[i];
            }
            return result;
        }

        public double Max(double[] nums)
        {
            double result = nums[0];
            for (int i = 0;i < nums.Length; i++)
            {
                if (nums[i] >= result)
                    result = nums[i];
            }
            return result;
        }

        public string Max(string[] nums)
        {
            string result = nums[0];
            for (int i = 0; i < nums.Length; i++)
            {
                if (nums[i].Length >= result.Length)
                    result = nums[i];
            }
            return result;
        }
