VB.NET如何获得CAD三维多线段的顶点数和三维坐标把cad文件导出STL文件vb.net多线段链接，然后用vb读取stl就可以vb.net多线段链接了
VB.NET 简单多线程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
End Sub
Private Sub addHandle()
For i As Integer = 0 To AnalysisNumber.Length - 1
AddHandler AnalysisNumber(i).DoWork, AddressOf AnalysisNumber_DoWork
AddHandler AnalysisNumber(i).RunWorkerCompleted, AddressOf AnalysisNumber_RunWorkerCompleted
Next
End Sub
Private Sub startWork()
For i As Integer = 0 To 9
Dim temp(0 To 9) As Integer
For j As Integer = 1 To 10
temp(j - 1) = 10 * i + j
Next
AnalysisNumber(i).RunWorkerAsync(temp)
Next
End Sub
Private Sub AnalysisNumber_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs)
Dim data As Integer()
data = https://www.04ip.com/post/CType(e.Argument, Integer())
Dim temp As Integer
For i As Integer = 0 To data.Length - 1
temp = data(i)
data(i) = temp * temp
Next
e.Result = data
End Sub
Private Sub AnalysisNumber_RunWorkerCompleted(ByVal sender As Object, ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs)
Dim data As Integer()
data = https://www.04ip.com/post/CType(e.Result, Integer())
For i As Integer = 0 To data.Length - 1
ListBox1.Items.Add(data(i))
Next
End Sub
End Class
在vb.net中，多线程如何使用Sub Main()Dim thr As New Thread(AddressOf 循环)thr.Start("a")End SubSub 循环(a() As String)'这里随vb.net多线段链接你干什么循环也行For Each i As String In aMsgBox(i)NextEnd Sub
VB.net 如何设计多线程运行Sub Main()
Dim thr As Thread
For Pi As Integer=0 To 4 //启用5线程
MulParams =PivbTabsFilevbTabdFilevbTab1vbTabDelNvbTabcrvbTabcgvbTabcbvbTabIndexI
GlobalParamas(pi)=MulParams .Split(vbTab)
thr=New Thread(AddressOf MyMulThreadCaller)
thr.Start() //启动多线程进程
Application.DoEvents
Next
End Sub
vb.net 循环使用多线程ListBox操作需要用Invoke 。另外多线程方式并不是并行处理 。
建议采用.net framework 4 带vb.net多线段链接的并行处理循环操作vb.net多线段链接，若不是4.0版本vb.net多线段链接的frameworkvb.net多线段链接，可以使用Aforge的并行库比较方便 。
