套接字访问非公共成员 [英] socket access non public member

问题描述

Hello
我正在开发Asyncronous套接字编程"UDP"

当你右键点击iar时，我想访问（（System.Net.Sockets.OverlappedAsyncResult）（iar））。m_SocketAddress。它是非公开成员。

public static void ReceiveCallback（IAsyncResult iar ）
{
我想要知道哪个服务器向我发送了消息
















































IPEndPoint（IPAddress.Any，1234）;
EndPoint rep =（EndPoint）sender;
int read = remort.EndReceiveFrom（iar，ref rep）;
if（read> 0）
{
_Objsock1234.BeginReceiveFrom（data，0，data.Length，0，ref rep，
new AsyncCallback（ReceiveCallback），_ Objsock1234）;
}

}


catch（Exception ex）
{
throw ex;
}

这是我

解决方案

>我想访问

您可以使用Reflection执行此操作，但它不会被认为是正确的。私有字段没有记录。

我建议您使用"状态"。 BeginReceiveFrom的参数。

< tr>


















< td>

public static void ReceiveCallback（IAsyncResult iar）

{

//您的代码

ReceiveState state =（ReceiveState）iar.AsyncState ;

IPEndPoint rep = state.IPEndPoint;

state.Socket.BeginReceiveFrom（data，0，data.Length，0， ref rep，

new 的AsyncCallback（ReceiveCallback），状态）;

//您的代码

}

private class ReceiveState

{

public Socket Socket { get ; set ; }

public IPEndPoint IPEndPoint { get ; set ; }

}

 Hello
           I am working on Asyncronous socket programing "UDP"

I want to access ((System.Net.Sockets.OverlappedAsyncResult)(iar)).m_SocketAddress when you rightclick on iar. it is a non public member.

public static void ReceiveCallback(IAsyncResult iar)
        {
Here I want to know which server has  send me the message
            try
            {
                lock (_lock)
                {
                   
                    Socket remort = (Socket)iar.AsyncState;
                    IPEndPoint sender = new IPEndPoint(IPAddress.Any , 1234);
                    EndPoint rep = (EndPoint)sender;
                    int read = remort.EndReceiveFrom(iar, ref rep);
                    if (read > 0)
                    {
                                              _Objsock1234.BeginReceiveFrom(data, 0, data.Length, 0, ref rep,
                                         new AsyncCallback(ReceiveCallback), _Objsock1234);
                    }

                }
            }
            catch (Exception ex)
            {
                throw ex;
            }

It's Me

解决方案

> I want to access

You could do this with Reflection, but it would not be considered proper.  Private fields are undocumented.

I suggest that you use the "state" parameter of BeginReceiveFrom for this.

public static void ReceiveCallback(IAsyncResult iar)

{

// Your code here

ReceiveState state = (ReceiveState)iar.AsyncState;

IPEndPoint rep = state.IPEndPoint;

state.Socket.BeginReceiveFrom(data, 0, data.Length, 0, ref rep,

new AsyncCallback(ReceiveCallback), state);

// Your code here

}

private class ReceiveState

{

public Socket Socket { get; set; }

public IPEndPoint IPEndPoint { get; set; }

}
