VB.net 数组怎么按任意元素的顺序排序输出

你直接传一个数组进去,而且是一个结构体数组,array.sort怎么知道根据结构中的哪一个属性进行排序?放一个c#的代码你看看,VB和C#很相似的

class Program

{

static void Main(string[] args)

{

People[] p = new People[3]

{

new People{name="张三"},

new People{name="李四"},

new People{name="张二名"}

};

//重点传一个实现了IComparer接口的类进去,告诉Array.Sort怎么排序

Array.Sort(p, new PeopleCompare());

foreach (var item in p)

{

Console.WriteLine(item.name);

}

Console.ReadKey();

}

}

//People结构体,换成类一样的

public struct People

{

public string name { get; set; }

}

//实现了IComparer接口的类

public class PeopleCompare : IComparer

{

public int Compare(object x, object y)

{

People p1 = (People)x ;

People p2 = (People)y;

return p1.name.CompareTo(p2.name);

}

}

vb6 数组如何排序

Sub Main()

Dim s()

s() = Array(0, 1, 1, 0, 2, 2, 3, 3, 3, 4, 5, 8, 0, 1, 6, 8, 3, 7)

Dim mr(1 To 6, 1 To 3) As Byte

Dim i As Long, j As Long, n As Long, st As String

For i = 1 To 6

For j = 1 To 3

mr(i, j) = s(n): n = n + 1

st = st mr(i, j) ","

Next

st = st vbCrLf

Next

Debug.Print st

'从这里开始

Dim x As Long, y As Long

Dim t1, t2, t3

For x = 1 To 5

For y = x + 1 To 6

If (mr(y, 1) 0 And mr(x, 1) mr(y, 1)) Or mr(x, 1) = 0 Then

'将符合条件的元素交换

t1 = mr(x, 1): t2 = mr(x, 2): t3 = mr(x, 3)

mr(x, 1) = mr(y, 1): mr(x, 2) = mr(y, 2): mr(x, 3) = mr(y, 3)

mr(y, 1) = t1: mr(y, 2) = t2: mr(y, 3) = t3

End If

Next

Next

st = "================" vbCrLf

For i = 1 To 6

If mr(i, 1) = 0 Then Exit For

For j = 1 To 3

st = st mr(i, j) ","

Next

st = st vbCrLf

Next

Debug.Print st

End Sub

VB中如何给指定的数组排序??

Private Sub Command4_Click()

Dim t As clerk, i%, j%

For i = 0 To n - 1

  For j = i To n - 2

      If a(i).vc a(j + 1).vc Then

          t = a(i): a(i) = a(j + 1): a(j + 1) = t

      End If

  Next j

Next i

Picture2.Cls

Picture2.Print "学号          姓名           VC            VB"

Picture2.Print "---------------------------------------------"

For i = 0 To n - 1

  Picture2.Print a(i).number, a(i).name, a(i).vc, a(i).vb

  Print

Next i

End Sub

扩展资料

vb数组排序思路:

1、冒泡排序法:

位置相邻两数进行两两比较,在比较时如果发现前面的数比后面的数大,则进行交换,都比较完一轮后,把最大一个数放到最后,如此进行下去即可完成冒泡排序。

2、比较交换法

假设第一个数最小,然后第一个数依次与后面的每个数都进行比较, 若比较时发现后面的数比第一个数小, 则两数位置进行交换, 全部都比较完算一轮,每一轮比较完后,第一个数是最小的数,如此进行即可完成比较排序。

3、选择排序

假设第一个数最小,接着记下最小数所在的位置,然后将最小数依次与后面的每一个数都进行比较,若比较时发现后面的数比最小的数还小,则修改最小数所在位置,全部都比较完算一轮。

每一轮比较完后,最小数所在的位置是否跟假设的是同一个位置,若不是,则最小数与第一个数进行交换位置,如此进行即可完成选择排序。

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

二维数组排序 vb.net

Dim i As Integer, j As Integer, X As Single, Y As Single, M As Single

i = L

j = R

'找出数组的中点

M = MyArray((L + R) / 2, 0)

While (i = j)

'找出比中点大的数

While (MyArray(i, 0) M And i R)

i = i + 1

Wend

'找出比中点小的数

While (M MyArray(j, 0) And j L)

j = j - 1

Wend

'互换这两个数

If (i = j) Then

X = MyArray(i, 0)

Y = MyArray(i, 1)

MyArray(i, 0) = MyArray(j, 0)

MyArray(i, 1) = MyArray(j, 1)

MyArray(j, 0) = X

MyArray(j, 1) = Y

i = i + 1

j = j - 1

End If

Wend

'未完成时递归调用

If (L j) Then Call QuickSort(MyArray(), L, j)

If (i R) Then Call QuickSort(MyArray(), i, R)

End Sub

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
