c# - 无法访问已处置的对象。套接字 C#

Question

我使用套接字，当我尝试关闭套接字时，我得到一个

ObjectDisposedException: Cannot access a disposed object Object name: 'System.Net.Sockets.Socket'.

异常。

        socket.Close();
        socket.Shutdown(SocketShutdown.Both);  <- exception

为什么会这样？垃圾收集器为什么要清理它？

Answer 1

Socket.Close的备注部分文档告诉你

For connection-oriented protocols, it is recommended that you call Shutdown before calling the Close method. This ensures that all data is sent and received on the connected socket before it is closed.

因此，您应该在 关闭 之前调用 Shutdown，而不是在之后

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