Complete the following method that merges 2 rectangular Int32 arrays:

public Int32[,] MergeArrays( Int32[,] Array1, Int32[,] Array2, MergeType Type)

{

Int32[,] retVal=null;

//--------------------------------------------------------

//Your code here!

//--------------------------------------------------------

return retVal;

Example: There are two arrays , array 1 has 1,2,3,3 and array 2 has 5,6,7,8 and we have to combine both array one and array two

1 2 5 6 = 1 2 5 6

3 4 7 8 3 4 7 8
