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
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
