Whilst you can use Array.Copy, for a given number of dimensions, you might find it easier to write a simple method which mimics what Array.Resize does for a single dimensional array. Here is such a method for resizing a two dimensional array: using System; class Test { static void Main() { // define 3 x 2 array int[,] ia = new int[3, 2]{ {1,2}, {3,4}, {5,6} }; // resize to 4 x 3 - extra elements will be zero by default Resize2D(ref ia, 4, 3); ia[3,2] = 9; // give one of new elements a non-default value // check it worked for(int i = 0; i { for(int j = 0; j { Console.Write("{0} ", ia[i,j]); } Console.WriteLine(); } Console.ReadKey(); } static void Resize2D (ref T[,] array, int newSizeX, int newSizeY) { int sizeX = array.GetLength(0); int sizeY = array.GetLength(1); if (sizeX == newSizeX && sizeY == newSizeY) return; // no change needed T[,] newArray = new T[newSizeX, newSizeY]; for (int i = 0; i { for (int j = 0; j { if (i } } array = newArray; } }

You'd have to copy it to a new array instance that has the desired dimensions.
