这真的可能吗？我有一个在Mac上运行的Java服务器程序，需要与Windows程序进行通信。我已经用Java编写了客户端，但似乎无法弄清如何在VB.net中使其工作...
以下是Java代码...
import java.io.*;
import java.net.InetAddress;
import java.net.Socket;
public class socketClient {
public static void main(String[] args) {
/**
* Define a host server
*/
String host = "10.1.1.194";
/**
* Define a port
*/
int port = 19999;
StringBuffer instr = new StringBuffer();
String TimeStamp;
System.out.println("SocketClient initialized");
try {
//Obtain an address object of the server
InetAddress address = InetAddress.getByName(host);
//Establish a socket connection
Socket connection = new Socket(address, port);
//Instantiate a BufferedOutputStream object
BufferedOutputStream bos = new BufferedOutputStream(connection.getOutputStream());
/**
* Instantiate an OutputStreamWriter object with the optional
* character encoding.
*/
OutputStreamWriter osw = new OutputStreamWriter(bos, "US-ASCII");
TimeStamp = new java.util.Date().toString();
String process = "Initiate file transfer on " + host + " port " + port
+ " at " + TimeStamp + (char) 13;
//Write across the socket connection and flush the buffer
osw.write(process);
osw.flush();
/**
* Instantiate a BufferedInputStream object for reading /**
* Instantiate a BufferedInputStream object for reading incoming
* socket streams.
*/
BufferedInputStream bis = new BufferedInputStream(connection.getInputStream());
/**
* Instantiate an InputStreamReader with the optional character
* encoding.
*/
InputStreamReader isr = new InputStreamReader(bis, "US-ASCII");
//Read the socket's InputStream and append to a StringBuffer
int c;
while ((c = isr.read()) != 13) {
instr.append((char) c);
}
//Close the socket connection.
connection.close();
System.out.println(instr);
}
catch (IOException f)
{
System.out.println("IOException: " + f);
}
catch (Exception g)
{
System.out.println("Exception: " + g);
}
}
}
这是我目前为止的VB.NET代码...
Private clientSocket As Socket
Private host As String = "10.1.1.194"
Private port As Integer = 19999
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Try
Dim add As New IPEndPoint(IPAddress.Parse(host), port)
clientSocket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)
clientSocket.Connect(add)
Dim netStream As New NetworkStream(clientSocket, True)
Dim outstream As Byte() = System.Text.Encoding.ASCII.GetBytes("Initiate file transfer from " _
& System.Environment.MachineName & " on " & host & " port " & port & " at " & TimeOfDay)
netStream.Write(outstream, 0, outstream.Length)
netStream.Flush()
Catch ex As Exception
Debug.Write(ex.Message)
End Try
End Sub
现在，如果我运行VB代码，它会挂起... 在我的Mac控制台上没有任何内容出现（就像我使用Java客户端时一样），然而，当我关闭VB代码时，我会得到java.net.SocketException：连接重置错误，所以我必须接近解决这个问题了。
问题是，当涉及到套接字编程时，我几乎一无所知，因此，如果有人能指导我正确的方向，我将不胜感激！
