The name 'list' does not exist in the current c# context, VS, what's the problem?

Question

C++ / C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace LMV_3
{
    class mainClass
    {
        List<Group> list = new List<Group>();
        list

        
    }
}

Answer 1

You don't have a method where you could use this list. Now you are declaring the variables of the mainClass class.

Answer 2

You write a class description, not a code algorithm
