[英]Sorting an array numerically (VB.NET)
I want to sort records based on their integer value in descending order: 我想根据记录的整数值按降序排序:
Example: 例:
name1, 4 name2, 6 name3, 3 name4, 5
Should be re - arranged to this: 应重新安排为此:
name2, 6 name4, 5 name1, 4 name3, 3
I've tried using the Array.Sort but I could not get it working. 我尝试使用Array.Sort,但无法正常工作。
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.sort
to sort based on the integers. 您可以将数据拆分为两个数组,并使用use
array.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
. 这将以
ia
升序对两个数组进行排序。 Iterate the arrays backward to get descending order. 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
