Sorting an array numerically (VB.NET)
提问by SkyTrees
I want to sort records based on their integer value in descending order:
我想根据整数值按降序对记录进行排序：
Example:
例子：
name1, 4 name2, 6 name3, 3 name4, 5
Should be re - arranged to this:
应该重新安排成这样：
name2, 6 name4, 5 name1, 4 name3, 3
I've tried using the Array.Sort but I could not get it working.
我试过使用 Array.Sort 但我无法让它工作。
As always I appreciate all of your help.
一如既往，我感谢您的所有帮助。

You can split the data into two arrays and use use array.sortto sort based on the integers.
您可以将数据拆分为两个数组，并使用 usearray.sort根据整数进行排序。
Dim a() As String = {"name1", "name2", "name3", "name4"}
Dim ia() As Integer = {4, 6, 3, 5}
Array.Sort(ia, a)
This will sort both arrays in ascending order of ia. Iterate the arrays backward to get descending order.
这将按 的升序对两个数组进行排序ia。向后迭代数组以获得降序。

Sub Main()
Dim StartArray(3) As Integer
'First let's assign the array elements before it is sorted
StartArray(0) = 4
StartArray(1) = 6
StartArray(2) = 3
StartArray(3) = 5
Array.Sort(StartArray) 'This sorts the array
For i As Integer = 0 To 3
Console.WriteLine(StartArray(i)) 'Prints the array elements to console
Next
Console.ReadLine()
End Sub

dim nos() as integer={1,2,3,4}
dim names() as string = {"a","b","c","d"}
for i = 0 to 3
array.sort(names &" "&nos)
next
console.readKey
