Question

正如我在标题中所说，服务器不会监听以前客户端的数据包。一世只需要服务器来读取来自多个客户端的所有数据包。

这是我的代码，谢谢你的帮助

    serverSocket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
    Dim ipAddress As IPAddress = ipAddress.Parse("192.168.2.202")
    Dim IpEndPoint As IPEndPoint = New IPEndPoint(ipAddress, 15002)
    serverSocket.Bind(IpEndPoint)
    serverSocket.Listen(1500)
    serverSocket.BeginAccept(New AsyncCallback(AddressOf OnAccept), Nothing)

委托Sub _OnAccept（ByVal ar As IAsyncResult） Private Sub OnAccept（ByVal ar As IAsyncResult）

    If InvokeRequired Then
        Invoke(New _OnAccept(AddressOf OnAccept), ar)

        Exit Sub
    End If

    clientSocket = serverSocket.EndAccept(ar)
    serverSocket.BeginAccept(New AsyncCallback(AddressOf OnAccept), Nothing)


    Try
        clientSocket.BeginReceive(byteData, 0, byteData.Length, SocketFlags.None, New AsyncCallback(AddressOf OnRecieve),

ClientSocket的）赶上前例外

    End Try


    AddClient(clientSocket)
End Sub
Delegate Sub _AddClient(ByVal client As Socket) 'delege used to invoke AddCLient()
Private Sub AddClient(ByVal client As Socket)

    If InvokeRequired Then
        Invoke(New _AddClient(AddressOf AddClient), client)

        Exit Sub
    End If
    Dim lvi As New ListViewItem(client.LocalEndPoint.ToString)
    lvi.Tag = client
    ListBox1.Items.Add(client.RemoteEndPoint.ToString & " Bağlandı")

End Sub

委托Sub _OnRecieve（ByVal ar As IAsyncResult） Private Sub OnRecieve（ByVal ar As IAsyncResult）如果InvokeRequired那么调用（新_OnRecieve（AddressOf OnRecieve），ar）退出子结束如果

    Dim client As Socket = ar.AsyncState
    Try
        client.EndReceive(ar)
    Catch ex As Exception

    End Try

    Dim bytesRec As Byte() = byteData
    Dim paket As String = System.Text.ASCIIEncoding.ASCII.GetString(bytesRec)

    Dim temizip As String
    temizip = Replace(paket, Chr(0), Chr(32))
    temizip = temizip.Trim

    Dim msg As String = temizip

    Try

        Dim boyut As Integer
        boyut = msg(0) & msg(1)
        boyut = boyut - 10

        Dim externalip As String
        externalip = msg.Remove(0, 2)
        externalip = externalip.Remove(boyut, (externalip.Length - boyut))

       If clientlist.Contains(externalip) Then
        Else
            clientlist.Add(externalip)

        End If





    Catch ex As Exception

    End Try


    Try
        clientSocket.BeginReceive(byteData, 0, byteData.Length, SocketFlags.None, New AsyncCallback(AddressOf OnRecieve),

ClientSocket的）赶上前例外

    End Try

End Sub

谢谢别人我解决了这个问题，我为每个客户宣布新的clientocket并解决了。我只是从头代码中删除了clientSocket变量，并在每个线程上重新声明它。

vb.net服务器Socket在新接受新客户端后解除以前的客户端
