Your code would have to compile first before you could try and execute it
public void MinVal(params int[] numbers)

Solution 2

try this, check in line comments.

C#

using System;
using System.Windows;  // Add this namespace
namespace LearnigToProgram
{
	class Min {
		public void MinVal(params int[] numbers) // only one variable name is a valid syntax
		{
			for (int i = 0; i < numbers.Length; i++)
			{
				Console.WriteLine(numbers[i]);
				Console.WriteLine();
			}
            Console.ReadLine(); //waits for input,  to view the output being displayed on the console window, else the window will be closed immeditely
		}
		
		}

		class ParamsDemo {
			static void Main() {
			Min obj1 = new Min();
			obj1.MinVal(1, 2, 3, 4, 5); 
			}
		}
	
	}

The only issue i see with your code is you have the array declaration wrong in your MinVal method.

The following code, only thing corrected being the array, compiles and runs as expected.

C#

static void Main(string[] args)
        {

            Min obj1 = new Min();
            obj1.MinVal(1, 2, 3, 4, 5);

            Console.ReadLine();
        }


        class Min
        {
            public void MinVal(params int[] numbers)
            {
                for (int i = 0; i < numbers.Length; i++)
                {
                    Console.WriteLine(numbers[i]);
                    Console.WriteLine();
                }
            }

        }
