Array.sort（）无法正常工作

Question

Suppose an array consists of values:

dim arrnum() as integer=nothing

arrnum consists of values (3,8,6,15,2,10)

while using Array.sort(arrnum) 

valuse are sorted like way. (10,15,2,3,6,5)

Actually I need values in a sorted way.

Can you help me out?

Answer 1

Assuming your sorted array is actually 10, 15, 2, 3, 6, 8 (ie, containing the same elements as the original), it looks like it's sorting lexicographically (a fancy way of saying string sorting rather than numeric sorting).

In other words, 10 and 15 are less than 2 if you're sorting based on character data, since 1 is less than 2 .

That makes me doubt the veracity of your statement that they're actually integers, so that would be the first thing I'd be checking.

Answer 2

I think you have some mistake to define array Take look below code this worked

Dim arrnum() As Integer = Nothing
arrnum = {3, 8, 6, 15, 2, 10}
Array.Sort(arrnum)

Answer 3

Unsuprisingly, the code

Sub Main
    Dim array = {3, 8, 6, 15, 2, 10}
    System.Array.Sort(array)
    Console.WriteLine(String.Join(", ", array))
    Console.ReadKey()
End Sub

works entirely as I would expect.

You are doing something(s) wrong.

Before we can help you out you need to show us exactly what you are doing.

I'm drawn to suggest you are sorting an array of String but the 6 and 5 in your results are reversed for alphabetical order. Note that the value 5 is not even present in the initial array. Additionaly, Array.Sort does not return anything so there would be nothing to pass to a using or while .
