关闭客户端程序后,出现错误“远程主机强制关闭现有连接”。我添加了此代码以确保在程序关闭时关闭客户端连接。
我还有一个关闭客户端的按钮,该按钮可以正常工作。
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
try
{
client.Close();
}
catch (CommunicationException ex)
{
client.Abort();
}
catch (TimeoutException ex)
{
client.Abort();
}
catch (Exception ex)
{
client.Abort();
throw ex;
}
}
我在这里想念什么吗?这是堆栈跟踪:
< StackTrace>
bei System.ServiceModel.Channels.SocketConnection.HandleReceiveAsyncCompleted()
bei System.ServiceModel.Channels.SocketConnection.OnReceiveAsync(Object sender, SocketAsyncEventArgs eventArgs)
bei System.ServiceModel.Channels.SocketConnection.OnReceiveAsyncCompleted(Object sender, SocketAsyncEventArgs e)

bei System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32 errorCode, UInt32 numBytes, NativeOverlapped* pOVERLAP)
< /StackTrace>
我希望堆栈跟踪可以帮助某人帮助我:D 我正在使用 nettcp,并且该错误仅在我关闭程序时发生。
谢谢,曼努埃尔
