vb.net线程多个参数 vbnet 多线程

IT技术线程

vb.net多线程如何返回参数，举个例子，谢谢Public Class Form1
Public Class SquareClass '把多线程调用的函数封装到类中，通过类事件返回
Public Value As Double
Public Square As Double
Public Event ThreadComplete(ByVal Square As Double)
Public Sub CalcSquare()
Square = Value * Value
RaiseEvent ThreadComplete(Square)
End Sub
End Class
Dim WithEvents oSquare As SquareClass
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click '多线程返回值测试 ， 当线程运行完成激发事件
oSquare = New SquareClass()
Dim t As New Threading.Thread(AddressOf oSquare.CalcSquare)
oSquare.Value = https://www.04ip.com/post/30
t.Start()
End Sub
Sub SquareEventHandler(ByVal Square As Double) Handles oSquare.ThreadComplete '响应事件函数
MsgBox("The square is "Square)
End Sub
End Class
Vb.net 怎样操作有参数的多线程而且还是循环的 。Sub Main()
Dim thr As New Thread(AddressOf 循环)
thr.Start("a")
End Sub
Sub 循环(a() As String)
'这里随你干什么循环也行
For Each i As String In a
MsgBox(i)
Next
End Sub
看懂了吧 参数只能有一个 也可以不是数组，在a() As String的a后面去掉括号就行
vb.net 怎样操作带参数的多线程public class threadclass
{
public int a;
public void threadmethod()
{
//use a;
}
}
...
threadclass tc = new ....
tc.a = 10;
Thread t = new ThreadStart(tc.threadmethod);
t.Start
