c＃如果捕获新方法的异常，GC会收集此对象吗？

Question

private void BeginListen()
{
    while (isWatch)
    {
        try
        {

            Socket newSocket = socket.Accept();
            ConnectionClient conn = new ConnectionClient(newSocket, ShowMsg, RemoveClientConnection, SendMsgToController);
            string strRemoteEndPoint = newSocket.RemoteEndPoint.ToString();
            if (dictConn.ContainsKey(strRemoteEndPoint.Substring(0, strRemoteEndPoint.LastIndexOf(":"))))
                dictConn[strRemoteEndPoint.Substring(0, strRemoteEndPoint.LastIndexOf(":"))].isRec = true;
            else
                dictConn.Add(strRemoteEndPoint.Substring(0, strRemoteEndPoint.LastIndexOf(":")), conn);
            UpdateControllerStatus(strRemoteEndPoint, " online");
        }
        catch (Exception ex)
        {
            ExceptionLog(ex);
        }
    }
}

This method is used for listening.

If I use thread to create this method

myThread = new Thread(new ThreadStart(BeginListen));
myThread.IsBackground = true;
myThread.Start();

Will it be collected by GC when catching an exception? Or do I need to add GC.Collect(); manually in the catch?

Answer 1

What do you want to be collected? Well, generally you shouldn't call GC.Collect yourself.

I would leave it for the GC to collect the objects and reclaim memory resources. But when something implements IDisposable, you generally should use the using statement.

In the example provided, maybe you don't need to use a using statement, because the socket may be used later, also, maybe there is already some code to dispose the object inside your ConnectionClient class. Disposing it now could cause you problems.

But generally you can use the using statement to automatically handle the disposal of resources, eg opening file streams, creating memory streams, and so on.
