How can I use a variable inside a for loop?

using System;

namespace something
{
    class Program
    {
        static void Main(string[] args)
        {
            int roomHeight = 10;
            int roomLength = 10;
            string Length;

            for (int i=0; i < roomLength; i++)
            {
                Length = string.Join(Length, ("a"));
            }
        }
    }
}

This doesn't compile, it does not recognize Length = string.Join(Length, ("a"));

I want it to recognize it as the string I declarated.

            int roomHeight = 10;
            int roomLength = 10;
            string length = string.Empty;

            for (int i=0; i< roomLength; i++)
            {
                length= string.Join(length, ("a"));
            }
        }
    }
}

Length needs to be assigned before you have it as a parameter in string.Join
