A Jagged array is an array of arrays. We can declare it in the below manner: string[][] sJaggedArray = new string[3][]; sJaggedArray[0] = new string[]{"One","Two","Three","Four"}; sJaggedArray[1] = new string[] { "One", "Two", "Three" }; sJaggedArray[2] = new string[] { "One", "Two" }; Each element of the array is another array in itself. Hope it helped
