i have a question regarding with Arrays:

I am wondering if your able to use a foreach in a multidimensional array. I am able to use a nested for loop to output the information. I am curious about it. I would greatly appreciate the help.

What is the point in using a foreach if you have an array?

Just use two for's:

for (int i = 0; i<n; i++)
     for (int j = 0; j<n; j++)
          Console.WriteLine(array[i][j]);

I realized that using a foreach is only meant for a single dimensional array. But, I just wanted to make sure that you still can use it for multidimensional

when you use foreach code is clean. You dont have to declare additional indexing variables.

Following code prodcues output: "1234".
Wthout any variable.

    class Program
    {
        static void Main(string[] args)
        {

            var array = new [,] {{1, 2}, {3, 4}};

            foreach (var value in array)
                Console.Write(value);

            Console.Read();
        }
    }
