Question

我正在尝试实现TcpClient并不断收到错误

请求的地址在其上下文中无效

但是，只有将代码放在主窗体调用的类中时才会发生这种情况。当我将代码放在主窗体中时（在窗体加载事件中），不会发生错误，并且TcpClient上的通信成功。

我试图使用Inherits ApplicationContext来装饰该类，但仍然会抛出错误。下面是我正在使用的代码：

班级

Public Class dasharClient

   Inherits ApplicationContext

    Public port As Integer
    Public hostname As String
    Private myClient As TcpClient
    Sub New()
        myClient = New TcpClient(hostname, port)
        Dim subscribe As Byte() = Encoding.ASCII.GetBytes("Hello World")
        myClient.GetStream.BeginWrite(subscribe, 0, subscribe.Length, AddressOf MyWriteCallBack, myClient.GetStream)
    End Sub
    Public Sub MyWriteCallBack(ByVal ar As IAsyncResult)
        CType(ar.AsyncState, NetworkStream).EndWrite(ar)
   End Sub
End Class

我从主窗体初始化类

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

    Dim testClass As New dasharClient With {.port = 3354, .hostname = "my.domain.com"}

End Sub

如上所述，如果我将类中的代码放入表单load event sub（没有类装饰），它就可以工作！
