copied!<p>I have written 2 methods which achieve the desired result</p> <pre><code> /// <summary> /// Converts the contents of a multidimensional array into a Jagged Array /// </summary> /// <param name="multiArray">the existing multidimensional array you wish to convert</param> /// <param name="numOfColumns">number of columns</param> /// <param name="numOfRows">number of rows</param> /// <returns>Jagged Array representation of multidimensional array passed</returns> private int[][] convertToJaggedArray(int [,] multiArray, int numOfColumns, int numOfRows) { int[][] jaggedArray = new int[numOfColumns][]; for (int c = 0; c < numOfColumns; c++) { jaggedArray[c] = new int[numOfRows]; for (int r = 0; r < numOfRows; r++) { jaggedArray[c][r] = multiArray[c, r]; } } return jaggedArray; } /// <summary> /// Converts the contents of a Jagged Array into a multidimensional array /// </summary> /// <param name="jaggedArray">The Jagged Array you wish to convert into a Multidimensional Array</param> /// <param name="numOfColumns">number of columns</param> /// <param name="numOfRows">number of rows</param> /// <returns>Multidimensional Array representation of Jagged Array passed</returns> private int[,] convertTo2DArray(int[][] jaggedArray, int numOfColumns, int numOfRows) { int[,] temp2DArray = new int[numOfColumns, numOfRows]; for (int c = 0; c < numOfColumns; c++) { for (int r = 0; r < numOfRows; r++) { temp2DArray[c, r] = jaggedArray[c][r]; } } return temp2DArray; } </code></pre> <p>then you simply pass your existing multidimensional or jagged array and it will return the same contents in a different array type. e.g.</p> <pre><code>//1. convert to Jagged print out, grid 1 is the existing 2d array instance here int[][] jaggedGrid = convertToJaggedArray(grid1, numOfCols, numOfRows); //2. Take the jagged and re-convert to multi array int[,] temp = convertTo2DArray(jaggedGrid, numOfCols, numOfRows); </code></pre> <p>You can also check and print out the contents of either by using the following loops</p> <pre><code>// Print out all elements in the jagged array to debugger. for (int c = 0; c < jaggedGrid.Length; c++) { int[] innerArray = jaggedGrid[c]; for (int r = 0; r < innerArray.Length; r++) { System.Diagnostics.Debug.WriteLine("In Jagged Array\nElement No ({0},{1})={2}", c, r, jaggedGrid[c][r] + "\n"); } } //print out all values in temp value 2d array to debugger for (int c = 0; c < temp.GetLength(0); c++) { for (int r = 0; r < temp.GetLength(1); r++) { System.Diagnostics.Debug.WriteLine("In temp array\nElement No ({0},{1})={2}", c, r, temp[c, r] + "\n"); } } </code></pre>
