C# and Array

If the arrays are of the same (or compatible) types and are of the same length, then you can combine them into a two dimensional array. However, this needs to be done manually as there is no specific method to do this to my knowledge. For example:

using System;

class Test
{
    static void Main()
    {
        int[] ArrayA = new int[]{1,2,3};
        int[] ArrayB = new int[]{4,5,6};
        int[,] ArrayC = new int[2,ArrayA.Length];
 
        for (int i = 0; i < ArrayC.GetLength(1); i++)
        {
            ArrayC[0,i] = ArrayA[i];
            ArrayC[1,i] = ArrayB[i];
        }
        
        for (int i = 0; i < ArrayC.GetLength(0); i++)
        {
           for (int j = 0; j < ArrayC.GetLength(1); j++)       
           {
              Console.WriteLine(ArrayC[i,j]);
           }
        }
        Console.ReadLine();
    }
}
