How do I sort a two-dimensional array in C#
To sort a two-dimensional array in C#, in a nested for loop, add another for loop to check the following condition.
Example
for (int k = 0; k < j; k++) {
if (arr[i, k] > arr[i, k + 1]) {
int myTemp = arr[i, k];
arr[i, k] = arr[i, k + 1];
arr[i, k + 1] = myTemp;
}
}Till the outer loop loops through, use the GetLength() method as shown below. This is done to sort the array.
Example
for (int i = 0; i < arr.GetLength(0); i++) {
for (int j = arr.GetLength(1) - 1; j > 0; j--) {
for (int k = 0; k < j; k++) {
if (arr[i, k] > arr[i, k + 1]) {
int myTemp = arr[i, k];
arr[i, k] = arr[i, k + 1];
arr[i, k + 1] = myTemp;
}
}
}
Console.WriteLine();
}
