Question

基本上，标题说明了一切;我有一个问题，我的传入连接添加到我的列表视图。（我将addclient函数放在一个单独的类中，该类将新的客户端添加到listview中，接受。

这是函数的代码：

     Delegate Sub _AddClient(ByVal Client As Socket)
    Public Sub AddClient(ByVal Client As Socket)
        Dim DummyString As String = ""
        Dim IPEP As String() = Client.LocalEndPoint.ToString.Split(":")
        Dim lvi As New ListViewItem(IPEP(0))


        lvi.Tag = Client
        lvi.SubItems.Add(IPEP(1))
        lvi.SubItems.Add(DummyString)
        lvi.SubItems.Add(DummyString)
        lvi.SubItems.Add(DummyString)
        lvi.SubItems.Add(DummyString)
        lvi.SubItems.Add(DummyString)
        lvi.SubItems.Add(DummyString)
        lvi.SubItems.Add(DummyString)
        lvi.SubItems.Add(DummyString)
        lvi.SubItems.Add(DummyString)
        If Form1.AeroListView1.InvokeRequired Then
            Form1.AeroListView1.Invoke(New _AddClient(AddressOf AddClient), Client)
            Exit Sub
        Else
            Form1.AeroListView1.Items.Add(lvi)
        End If

    End Sub

提前致谢！

您的方法需要对If语句使用Else块。你这样做：

If someControl.InvokeRequired Then
    someControl.Invoke(someDelegate)
End If

'Update the UI here.

当你应该做的是这样的：

If someControl.InvokeRequired Then
    someControl.Invoke(someDelegate)
Else
    'Update the UI here.
End If

无法从其他线程向listview添加项目
