vb.net冒泡法排序,vb冒泡排序和选择排序
vb编程 产生10个50-100(包括50和100)的随机整数，并用“冒泡排序”按从小到大的顺序输出。

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

vb.net的随机3个数字，然后排序一下
给你一个最简单的冒泡排序代码：
将三个数放到一个数组中。
a(0)=val(text1.text):a(1)=val(text2.text):a(2)=val(text3.text)
dim flag as Boolean,temp as Integer
for i = 0 to 2
flag = true
for j = 2 to 1
if a(j)a(j-1) then
temp = a(j-1)
a(j-1) = a(j)
a(j) = temp
flag = false
end if
next j
if flag then Exit For
next i
text4.text=a(0):text5.text=a(1):text6.text=a(2)
vb.net冒泡排序法代码
试试看：
For i = LBound(moto) To UBound(moto) - 1
For j = LBound(moto) To UBound(moto) - 1 - i
If moto(j) moto(j + 1) Then
t = moto(j)
moto(j) = moto(j + 1)
moto(j + 1) = t
End If
Next j
Next i
For i = LBound(moto) To UBound(moto)
Print moto(i);
Next i
编写一个 VB.NET 程序,产生 100 个 100 以内的随机数，将他们从大到小排序后输出
Private Sub Command1_Click()
Dim a(1 To 100) As Integer
Dim i As Integer, j As Integer, k As Integer
For i = 1 To 100 '给数组a一百个元素赋值，并换每行十个数字输出来窗体上
a(i) = Int(Rnd * 101)
k = k + 1
Print Tab((k - 1) * 5); a(i);
If k = 10 Then k = 0: Print
Next i
For i = 100 To 2 Step -1 '用冒泡排序法对数组进行排序
For j = 1 To i - 1
If a(j) a(j + 1) Then
t = a(j): a(j) = a(j + 1): a(j + 1) = t
End If
Next j
Next i
For i = 1 To 100 '输出排好序的数组
k = k + 1
Print Tab((k - 1) * 5); a(i);
If k = 10 Then k = 0: Print
Next i
End Sub
VB.NET中的“冒泡排序”问题
如果五个号码为数组元素（1）到（5），正确的排序过程：
对于i = 1至4
对于L = 1到5 - 如果A（L）（L +1）
N = A（L）
A（L），= A（L +1）
（L +1） =
结束如果下一页l
接下来，我
能够到第一台计算机来验证结果，然后分析程序。
