Question

首先感谢所有人......

我目前正在研究VB。我正在使用Visual Studio 2008。

下面的代码是一个没有任何错误的构建控制台应用程序。

    Imports System.Net


Module Module1

    Public Sub Main()

        Dim address As IPAddress
        Dim remoteIP As System.Net.IPEndPoint
        Dim socketAddress As System.Net.SocketAddress

        Try
            address = IPAddress.Parse("192.168.0.187")
            remoteIP = New System.Net.IPEndPoint(address, 0)

            socketAddress = remoteIP.Serialize()

            Console.WriteLine("Address Family :" & remoteIP.AddressFamily.ToString())
            Console.WriteLine("IP :" & remoteIP.Address.ToString() & "Port :" & remoteIP.Port.ToString())
            Console.WriteLine("Socket address :" & socketAddress.ToString())


        Catch ex As Exception
            Console.WriteLine(ex.StackTrace.ToString())


        End Try

    End Sub


End Module

在下一个dll程序中，同样给出错误说“预期addr，remoteIP和socketAddr声明”

Imports System.Net

Public Class Class1


End Class
Public Class ethernet

    Dim addr As IPAddress
    Dim remoteIP As System.Net.IPEndPoint
    Dim socketAddr As System.Net.SocketAddress

    addr = IPAddress.Parse("192.168.0.187")
    remoteIP = New System.Net.IPEndPoint(addr,0)

    socketAddr = remoteIP.Serialize()



End Class

有人能告诉我为什么会这样吗......

第二课ethernet中的代码未包含在方法中，因此您只声明addr, remoteIP和socketAddr个变量。

为了完成这项工作，只需将代码放在一个方法中，例如：

Public Class ethernet
    Public Function SerializeSocket(address As String) As System.Net.SocketAddress
        Dim addr As IPAddress = IPAddress.Parse("192.168.0.187")
        Dim remoteIP As System.Net.IPEndPoint = New System.Net.IPEndPoint(addr,0)
        Return remoteIP.Serialize()
    End Sub
End Class

VB dll中预期的声明
