VB.NET中数据的排序问题

建议用 DataGridView（vb.net排序数据你用vb.net排序数据的是它吧vb.net排序数据？）内建vb.net排序数据的排序方法来排序。介绍和示例代码可以参考MSDNvb.net排序数据：

Q1: VB.NET 2维数组排序排序和赋值问题

窗体上添加3个标签，1个按钮，在按钮的单击事件里写代码，如下：

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim a(,) As Integer = {{5, 6}, {1, 3}, {8, 9}, {72, 1}, {63, 4}}

Dim Temp As Integer

Dim i As Integer

Dim j As Integer

Dim x As Integer

Dim y As Integer

'显示排序前的数据

Label1.Text = "排序前数据：" vbCrLf

For i = 0 To 4

Label1.Text = Label1.Text a(i, 0) " " a(i, 1) vbCrLf

Next

For i = 0 To 3

For j = i + 1 To 4

If a(i, 0) a(j, 0) Then

Temp = a(i, 0)

a(i, 0) = a(j, 0)

a(j, 0) = Temp

Temp = a(i, 1)

a(i, 1) = a(j, 1)

a(j, 1) = Temp

End If

Next

Next

'显示排序前的数据

Label2.Text = "排序后数据：" vbCrLf

For i = 0 To 4

Label2.Text = Label2.Text a(i, 0) " " a(i, 1) vbCrLf

Next

'把第3行元素赋予X,Y

x = a(2, 0)

y = a(2, 1)

'输出X,Y

Label3.Text = "X=" x vbCrLf "Y=" y

End Sub

Q2: VB.NET数组的排序法？

如果你是从vb6刚过渡上vb。net，建议还是用冒泡排序法，容易理解。

如果你正努力学习vb。net的方法，推荐一个例子如下：

Imports System

Imports System.Collections

Public Class SamplesArray

Public Class myReverserClass

Implements IComparer

' Calls CaseInsensitiveComparer.Compare with the parameters reversed.

Function Compare(x As Object, y As Object) As Integer _

Implements IComparer.Compare

Return New CaseInsensitiveComparer().Compare(y, x)

End Function 'IComparer.Compare

End Class 'myReverserClass

Public Shared Sub Main()

' Creates and initializes a new Array and a new custom comparer.

Dim myArr As [String]() = {"The", "QUICK", "BROWN", "FOX", "jumps", "over", "the", "lazy", "dog"}

Dim myComparer = New myReverserClass()

' Displays the values of the Array.

Console.WriteLine("The Array initially contains the following values:")

PrintIndexAndValues(myArr)

' Sorts a section of the Array using the default comparer.

Array.Sort(myArr, 1, 3)

Console.WriteLine("After sorting a section of the Array using the default comparer:")

PrintIndexAndValues(myArr)

' Sorts a section of the Array using the reverse case-insensitive comparer.

Array.Sort(myArr, 1, 3, myComparer)

Console.WriteLine("After sorting a section of the Array using the reverse case-insensitive comparer:")

PrintIndexAndValues(myArr)

' Sorts the entire Array using the default comparer.

Array.Sort(myArr)

Console.WriteLine("After sorting the entire Array using the default comparer:")

PrintIndexAndValues(myArr)

' Sorts the entire Array using the reverse case-insensitive comparer.

Array.Sort(myArr, myComparer)

Console.WriteLine("After sorting the entire Array using the reverse case-insensitive comparer:")

PrintIndexAndValues(myArr)

End Sub 'Main

Public Shared Sub PrintIndexAndValues(myArr() As [String])

Dim i As Integer

For i = 0 To myArr.Length - 1

Console.WriteLine(" [{0}] : {1}", i, myArr(i))

Next i

Console.WriteLine()

End Sub 'PrintIndexAndValues

End Class 'SamplesArray

'This code produces the following output.

'

'The Array initially contains the following values:

' [0] : The

' [1] : QUICK

' [2] : BROWN

' [3] : FOX

' [4] : jumps

' [5] : over

' [6] : the

' [7] : lazy

' [8] : dog

Q3: vb.net 如何对数据库查询结果记录集排序？

加了单引号就是一个常量字符串了，对于每一行都是一样的

像这种放在最前面的字段，order by 1 就可以了
