Socket 关闭时出现 错误："由于套接字没有连接并且(当使用一个 sendto 调用发送数据报套接字时)没有提供地址，发送或接收数据的请求没有被接受。"

[csgxiao]

代码：

public void State()
{
try
{
mythread = new Thread(new ThreadStart(BeginListen));
mythread.Start();
}
catch (Exception ex)
{
eventLog_SendWorks.WriteEntry("监听端口线程启动错误提示：" + ex.Message, EventLogEntryType.Error);
}
}
public void Close()
{
try
{
//System.Environment.Exit(System.Environment.ExitCode);

socket.Shutdown(SocketShutdown.Both);
socket.Close();
mythread.Abort();
}
catch (ObjectDisposedException ex)
{
eventLog_SendWorks.WriteEntry("ObjectDisposedException错误！："+ex.Message,EventLogEntryType.Error);
}
catch (Exception ex)
{

eventLog_SendWorks.WriteEntry("关闭Socket和Thread是出错:" + ex.Message, EventLogEntryType.Error);
}
}




public static IPAddress GetServerIP()
{
IPHostEntry ieh = Dns.GetHostEntry(Dns.GetHostName()); //获取本地主机的地址
return ieh.AddressList[0];
}
private void BeginListen()
{
IPAddress ServerIp = GetServerIP();
IPEndPoint iep = new IPEndPoint(ServerIp, 8000);
socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

byte[] byteMessage = new byte[1024];

socket.Bind(iep);

while (true)
{
try
{
socket.Listen(5);
Socket newSocket = socket.Accept();
newSocket.Receive(byteMessage);

newSocket.Shutdown(SocketShutdown.Both);
newSocket.Close();

string msg = Encoding.Default.GetString(byteMessage);
msg = msg.Substring(0, 13);
if (msg == "ProWorkUpdate")
{
try
{
eventLog_SendWorks.WriteEntry("数据库更新，更新数据！");

我也遇到这个问题。在找资料
