VB.NET是否有数组排序方法游戏中遇到这样vb.net如何打乱数组的问题vb.net如何打乱数组,需要将一组已知的数据打乱vb.net如何打乱数组,按照以前和现在的做法vb.net如何打乱数组,总结vb.net如何打乱数组了以下方法 。
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
VB.NET数组的排序法?如果vb.net如何打乱数组你是从vb6刚过渡上vb 。net,建议还是用冒泡排序法,容易理解 。
如果vb.net如何打乱数组你正努力学习vb 。netvb.net如何打乱数组的方法,推荐一个例子如下vb.net如何打乱数组:
【vb.net如何打乱数组 vbnet数组排序方法】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)

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

VB 打乱数组 简单的说就是有一个数组(1,2,3,4) 他这个数组顺序打乱!求高人指点Dim a(20), k
Dim i As Integer, j As Integer
Randomize
For i = 0 To 20
a(i) = i
Next
Print "原始数组:"Join(a, ", ")
For i = 0 To 20
j = Int(Rnd * (UBound(a)1))
k = a(i)
a(i) = a(j)
a(j) = k
Next
Print "打乱后的:"Join(a, ", ")
