Sorting an array in Visual Basic .NET can be accomplished using the Array.Sort method. This method sorts the elements in an one-dimensional array of primitive data types or objects that implement the IComparable interface.
Here is an example of sorting an array of integers in ascending order:
Dim numbers() As Integer = {3, 1, 4, 1, 5, 9, 2, 6, 5}
Array.Sort(numbers)
The resulting numbers array will be sorted in ascending order: {1, 1, 2, 3, 4, 5, 5, 6, 9}.
Here is an example of sorting an array of strings in descending order:
Dim names() As String = {"Alice", "Bob", "Charlie", "Dave"}
Array.Sort(names, New Comparison(Of String)(Function(x, y) String.Compare(y, x)))
The Array.Sort method uses a comparison delegate to determine the sort order. In this example, the String.Compare method is used to determine the sort order, and the delegate is passed as an argument to the Array.Sort method. The resulting names array will be sorted in descending order: {"Dave", "Charlie", "Bob", "Alice"}.
It is also possible to sort an array of custom objects by implementing the IComparable interface on the object and calling the Array.Sort method. In this case, the CompareTo method of the object will be used to determine the sort order.
