C# Sort For Loop

When working with lists or arrays in C#, it's often necessary to sort the elements in a specific order. One way to achieve this is through the use of a for loop and the Sort method.

Syntax

The Sort method is used to sort the elements in a list or array in ascending order. The syntax for using this method is:

Array.Sort(array);

or

List.Sort();

where array is the name of the array and List is the name of the list.

Example

Here's an example of how to use the Sort method in a for loop:

int[] numbers = { 3, 7, 1, 9, 2, 6, 4, 5 };

for (int i = 0; i < numbers.Length; i++)
{
    for (int j = i + 1; j < numbers.Length; j++)
    {
        if (numbers[j] < numbers[i])
        {
            int temp = numbers[i];
            numbers[i] = numbers[j];
            numbers[j] = temp;
        }
    }
}

foreach (int number in numbers)
{
    Console.WriteLine(number);
}

In this example, we have an array of integers called numbers. We use a nested for loop to iterate over each element of the array and compare it to the other elements. If a smaller element is found, we swap the values using a temporary variable called temp. Finally, we use a foreach loop to print out the sorted elements in ascending order.

Conclusion

Using a for loop and the Sort method is a simple and effective way to sort lists and arrays in C#. This method can be customized to sort elements in descending order or by different criteria by using custom comparers.
