多线程一般是不推荐用的,因为线程之间如果有共享资源的话会引起竞争,需要加锁处理；而且线程间没有时序关系,所以你在调试中可能会出现异步处理结束顺序与开始处理顺序不一致的情况（我在调试中已经发现该问题）.
针对你提出的这个问题,采用了多线程处理,利用的是BackgroundWorker也就是异步处理控件进行了处理.
代码已经经过调试通过.欢迎交流,如有问题,留下QQ或其他联系方式.
代码如下,并附程序截图.
'---------------------------------------------------
Imports?System.ComponentModel?'导入异步控件命名空间
Public?Class?Form1
Private?howmany?As?Integer?=?10
Private?AnalysisNumber(0?To?howmany?-?1)?As?BackgroundWorker
Private?Sub?Button1_Click(ByVal?sender?As?System.Object,?ByVal?e?As?System.EventArgs)?Handles?Button1.Click
ListBox1.Items.Clear()
creatNewBackgroundWorker()
addHandle()
startWork()
End?Sub
Private?Sub?creatNewBackgroundWorker()
For?i?As?Integer?=?0?To?AnalysisNumber.Length?-?1
AnalysisNumber(i)?=?New?BackgroundWorker
Next
Private?Sub?addHandle()
AddHandler?AnalysisNumber(i).DoWork,?AddressOf?AnalysisNumber_DoWork
AddHandler?AnalysisNumber(i).RunWorkerCompleted,?AddressOf?AnalysisNumber_RunWorkerCompleted
Private?Sub?startWork()
For?j?As?Integer?=?1?To?10
temp(j?-?1)?=?10?*?i?+?j
AnalysisNumber(i).RunWorkerAsync(temp)
Private?Sub?AnalysisNumber_DoWork(ByVal?sender?As?Object,?ByVal?e?As?System.ComponentModel.DoWorkEventArgs)
Dim?data?As?Integer()
data?=?CType(e.Argument,?Integer())
Dim?temp?As?Integer
For?i?As?Integer?=?0?To?data.Length?-?1
temp?=?data(i)
data(i)?=?temp?*?temp
e.Result?=?data
Private?Sub?AnalysisNumber_RunWorkerCompleted(ByVal?sender?As?Object,?ByVal?e?As?System.ComponentModel.RunWorkerCompletedEventArgs)
data?=?CType(e.Result,?Integer())
ListBox1.Items.Add(data(i))
End?Class
Sub Main()
Dim thr As Thread
MulParams =Pi vbTab sFile vbTab dFile vbTab 1 vbTab DelN vbTab cr vbTab cg vbTab cb vbTab IndexI
GlobalParamas(pi)=MulParams .Split(vbTab)
thr=New Thread(AddressOf MyMulThreadCaller)
thr.Start() //启动多线程进程
Application.DoEvents
End Sub
线程结束后利用委托生成事件返回,线程应用包括传入和传出参数.
Public Delegate Sub ThreadCallback(value As ThreadResult)
Public Class Form1
Private WithEvents _th_1 As Thread_1
Protected Overrides Sub OnLoad(e As System.EventArgs)
Dim value As ThreadObject
value.Index = 1
Me._th_1 = New Thread_1(Me)
Me._th_1.Run(value)
MyBase.OnLoad(e)
Private Sub Thread_1_End(sender As Object, e As ThreadEventArgs) Handles _th_1.ThreadEnd
Me.TextBox1.Text = e.Result.Text
End Class
Public Class Thread_1
Public Event ThreadEnd(sender As Object, e As ThreadEventArgs)
Private _control As Control
Sub New(control As Control)
Me._control = control
Public Sub Run(value As Object)
Dim th As New Threading.Thread(AddressOf ThreadProc)
th.Start(value)
Private Sub ThreadProc(obj As Object)
Dim value As ThreadObject = CType(obj, ThreadObject)
Dim result As ThreadResult = Nothing
If value.Index = 1 Then result.Text = "测试"
Dim callback As New ThreadCallback(AddressOf ThreadInvoke)
_control.Invoke(callback, result)
Private Sub ThreadInvoke(value As ThreadResult)
RaiseEvent ThreadEnd(Me, New ThreadEventArgs(value))
Public Structure ThreadObject
Public Index As Integer
'Public Rect As Rectangle
End Structure
Public Structure ThreadResult
Public Text As String
Public Class ThreadEventArgs
Inherits System.EventArgs
Private _result As ThreadResult
Public ReadOnly Property Result As ThreadResult
Get
Return _result
End Get
End Property
Sub New(value As ThreadResult)
Me._result = value
多线程是用于处理复杂项目的
打个比方
按你的要求其实你的代码用不到多线程,只要把sleep放到两段代码中间就可以了.
新线程结束用thread.abort()
