vb.net数组数据整理 vbs数组操作

vb.net 怎么把数组分成若干份

不需要用数组：

假设已经存在vb.net数组数据整理的图片文件存放在 C：\图片 文件夹里vb.net数组数据整理，并假设新创建的文件夹位于C：\图片 文件夹里。

在窗体上添加一个按钮vb.net数组数据整理，代码如下：

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

Dim n As Long = -1

Dim P As Long = -1

Dim Pn As String

Dim MyNum As Integer = 100 '每100个文件存放在一个文件夹里

Dim MyPath As String

Dim MyFileName As String

Button1.Enabled = False

MyPath = "C:\图片\" '指定已有图片的路径

MyFileName = UCase(Dir(MyPath, FileAttribute.Normal)) ' 找寻第一项。

Do While MyFileName "" ' 开始循环。

If InStr(MyFileName, "JPG") 0 Or InStr(MyFileName, "GIF") 0 Or InStr(MyFileName, "PNG") 0 Then

n = n + 1

If n \ MyNum P Then

P = P + 1

Pn = CStr(n \ MyNum + 1)

MkDir(MyPath Pn)

End If

FileCopy(MyPath MyFileName, MyPath Pn "\" MyFileName)

End If

MyFileName = UCase(Dir()) ' 查找下一项

Loop

Button1.Enabled = True

End Sub

代码通过测试。

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vb.net数组数据整理你是从vb6刚过渡上vb。netvb.net数组数据整理，建议还是用冒泡排序法vb.net数组数据整理，容易理解。

如果你正努力学习vb。netvb.net数组数据整理的方法，推荐一个例子如下vb.net数组数据整理：

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.

'

Q3: VB.NET是否有数组排序方法

游戏中遇到这样的问题，需要将一组已知的数据打乱，按照以前和现在的做法，总结了以下方法。

方法一，最笨的菜鸟方法，也是容易想到的（幸好我没想过这种方法 :)）

从已知数组中随机一个数，然后加入到另一个数组中，在加入之前，先检查是否已经加入过。

这种方法有很大运气成分，且数据越大，效率越低，超过一定数目，则程序几乎无法执行，会一直卡在那里，代码：

[java] view plain copy

package com.test;

import java.util.Random;

public class TestArray {

public static int runCount =0;//用于记录方法运算次数

Q4: 在VB.net中，如何把listbox中的数值进行排序

Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

ListBox1.Items.Add("Apple")

ListBox1.Items.Add("Cat")

ListBox1.Items.Add("Yellow")

ListBox1.Items.Add("Guilty")

End Sub

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

ListBox1.Sorted = True

End Sub

End Class

Q5: vb.net 对象数组

你只是定义了一个对象，类而已

首先要给对象设置变量，这个还不是数组

Public class As Single的class 应该是关键字请换一个名字

Dim KidsX(1 to 100) as kids

KidsX(1).classx=1

KidsX(1).grade=1

KidsX(1).name=”张某"

KidsX(2).classx=1

KidsX(2).grade=2

KidsX(2).name=”王某"
