Two Dimensional Array

Question

Hi Dudes Any one can help me that how can i increase the size of two or multidimensional Array...?

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]{ {12} {34} {56} }; // resize to 4 x 3 - extra elements will be zero by default Resize2D(ref ia 4 3); ia[32] = 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[ij]); } 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.
