Hi astrodileepa,

Here is LNIQ soarting. When you working with collections always there is LINQ/ Lambda option for you. 

var result = myArray.OrderBy(row => row[columnIndex])

Hope that helps

Hi Dileepa S. Rajapaksa ,

Take a look at Sorting a Two-Dimensional Array in C#

Firstlly,Using Linq and extension methods , After that simply do something like the following

int[,] array = new int[3, 3] { { 1, 4, 2 }, { 4, 5, 1 }, { 7, 3, 8 } };
 
int[,] sortedByFirstElement = array.OrderBy(x => x[0]);
int[,] sortedBySecondElement = array.OrderBy(x => x[1]);
int[,] sortedByThirdElement = array.OrderBy(x => x[2]);

Have a nice day!
