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.
'
'The Array initially contains the following values:
' [0] : The

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"
