2DArray method:It will allocate a block of memory which represents a two-dimension arraybased on the input values supplied by the user. Ask the user to enter the number of rows andcolumn for 2D array that the user want to manipulate. The number of rows and columns that theuser enters may or may not define a square matrix (when the number of rows equals the numberof columns). The array will have exactly rows time columns (m * n) elements. It will notcontain any extra or empty cells. Initialize the “matrix” by rows with random number between 1to 100. Pass two arguments by out reference so that you can assign the number of row andcolumns of data to the first and second arguments. This is return 2D array method afterallocating new memory for 2D array and initialize it with random value. Generate randomnumber code in C# as following: Random randnum = new Random( );int number = randnum.Next (1, 101);SwapRow method: it will rotate the data in the matrix in an up/down method such that the…
