Are 2 dimensional Lists possible in c#?

Question

I\'d like to set up a multidimensional list. For reference, I am working on a playlist analyzer.

I have a file/file-list, which my program saves in a standard list.

Here's a little something that I made a while ago for a game engine I was working on. It was used as a local object variable holder. Basically, you use it as a normal list, but it holds the value at the position of what ever the string name is(or ID). A bit of modification, and you will have your 2D list.

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

namespace GameEngineInterpreter
{
    public class VariableList
    {
        private List list1;
        private List list2;

        /// 

        /// Initialize a new Variable List
        /// 
        public VariableList()
        {
            list1 = new List();
            list2 = new List();
        }

        /// 

        /// Set the value of a variable. If the variable does not exist, then it is created
        /// 
        /// Name or ID of the variable
        /// The value of the variable
        public void Set(string variable, T value)
        {
            if (!list1.Contains(variable))
            {
                list1.Add(variable);
                list2.Add(value);
            }
            else
            {
                list2[list1.IndexOf(variable)] = value;
            }
        }

        /// 

        /// Remove the variable if it exists
        /// 
        /// Name or ID of the variable
        public void Remove(string variable)
        {
            if (list1.Contains(variable))
            {
                list2.RemoveAt(list1.IndexOf(variable));
                list1.RemoveAt(list1.IndexOf(variable));
            }
        }

        /// 

        /// Clears the variable list
        /// 
        public void Clear()
        {
            list1.Clear();
            list2.Clear();
        }

        /// 

        /// Get the value of the variable if it exists
        /// 
        /// Name or ID of the variable
        /// Value
        public T Get(string variable)
        {
            if (list1.Contains(variable))
            {
                return (list2[list1.IndexOf(variable)]);
            }
            else
            {
                return default(T);
            }
        }

        /// 

        /// Get a string list of all the variables 
        /// 
        /// List string
        public List GetList()
        {
            return (list1);
        }
    }
}
