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)

End Sub

Private Sub Thread_1_End(sender As Object, e As ThreadEventArgs) Handles _th_1.ThreadEnd

Me.TextBox1.Text = e.Result.Text

End Sub

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

End Sub

Public Sub Run(value As Object)

Dim th As New Threading.Thread(AddressOf ThreadProc)

th.Start(value)

End Sub

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)

End Sub

Private Sub ThreadInvoke(value As ThreadResult)

RaiseEvent ThreadEnd(Me, New ThreadEventArgs(value))

End Sub

End Class

Public Structure ThreadObject

Public Index As Integer

'Public Rect As Rectangle

End Structure

Public Structure ThreadResult

Public Text As String

'Public Rect As Rectangle

End Structure

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

End Sub

End Class

vb.net 给委托的函数传递参数

两个参数：一个是数组名,一个是传递的长度

Function thename(ByVal imgFrom As Image) As String

thename = imgFrom.Name

End Function

Private Sub Image1_Click()

MsgBox thename(Image1)

End Sub

VB.NET中传递参数有哪些方式？

byval

byref

Of

Optional

ParamArray

在Visual stdio 工程中写 public sub AA(

下面自动出现这五个.

你这个默认是指自动生成的方法(过程\函数)吗?

那么默认是值传递Byval

要是自己写函数.则无参为默认
