AsyncCallback上的acceptcallback替换(acceptcallback replacement on AsyncCallback)

AsyncCallback上的acceptcallback替换(acceptcallback replacement on AsyncCallback)

我在网站http://www.codeproject.com/Articles/463947/Working-with-Sockets-in-Csharp上关注这个例子，以便构建一个套接字程序。

我只是想知道在以下代码下什么是acceptcallback的替代品。

Socket sListener; SocketPermission sPermission = new SocketPermission(NetworkAccess.Accept, TransportType.Tcp, "", SocketPermission.AllPorts); sListener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPHostEntry ipHost = Dns.GetHostEntry(""); IPAddress ipAddr = ipHost.AddressList[0]; IPEndPoint ipEndP = new IPEndPoint(ipAddr, 4510); sListener.Bind(ipEndP); sListener.Listen(10); //error below this AsyncCallback aCallback = new AsyncCallback(AcceptCallback); sListener.BeginAccept(aCallback, sListener); ....

我搜索网并尝试以下但似乎没有任何作用：

AsyncCallback aCallback = new AsyncCallback(AcceptCallback); AsyncCallback aCallback = new AsyncCallback(sListener.AcceptCallback); AsyncCallback aCallback = new AsyncCallback(this.AcceptCallback); AsyncCallback aCallback = new AsyncCallback(this.IAsyncResult); AsyncCallback aCallback = new AsyncCallback(aCallback); AsyncCallback aCallback = new AsyncCallback(sListener.aCallback); AsyncCallback aCallback = new AsyncCallback(this.aCallback);

我正在看的另一个参考是https://stackoverflow.com/questions/3722270/c-sharp-server-does-not-trigger-acceptcallback

这是我第一次在C＃中使用套接字。

I'm following the example on a site http://www.codeproject.com/Articles/463947/Working-with-Sockets-in-Csharp in order to build a socket program.

I was just wondering what is the replacement for acceptcallback under the following code.

Socket sListener; SocketPermission sPermission = new SocketPermission(NetworkAccess.Accept, TransportType.Tcp, "", SocketPermission.AllPorts); sListener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPHostEntry ipHost = Dns.GetHostEntry(""); IPAddress ipAddr = ipHost.AddressList[0]; IPEndPoint ipEndP = new IPEndPoint(ipAddr, 4510); sListener.Bind(ipEndP); sListener.Listen(10); //error below this AsyncCallback aCallback = new AsyncCallback(AcceptCallback); sListener.BeginAccept(aCallback, sListener); ....

I search the net and tried the following but nothing seems to work:

AsyncCallback aCallback = new AsyncCallback(AcceptCallback); AsyncCallback aCallback = new AsyncCallback(sListener.AcceptCallback); AsyncCallback aCallback = new AsyncCallback(this.AcceptCallback); AsyncCallback aCallback = new AsyncCallback(this.IAsyncResult); AsyncCallback aCallback = new AsyncCallback(aCallback); AsyncCallback aCallback = new AsyncCallback(sListener.aCallback); AsyncCallback aCallback = new AsyncCallback(this.aCallback);

another reference i was looking at was https://stackoverflow.com/questions/3722270/c-sharp-server-does-not-trigger-acceptcallback

This is my first time doing sockets in C#.

最满意答案

AcceptCallback是您创建的方法，在异步操作完成时会被调用。

看看在以下位置找到的示例：

http：// msdn.microsoft.com/en-us/library/system.asynccallback.aspx

// Create the delegate that will process the results of the // asynchronous request. AsyncCallback callBack = new AsyncCallback(ProcessDnsInformation); // The following method is called when each asynchronous operation completes. static void ProcessDnsInformation(IAsyncResult result) { ...

AcceptCallback is a method you create and that gets called when the asynchronous operation completes.

Look at the example found at:

http://msdn.microsoft.com/en-us/library/system.asynccallback.aspx

// Create the delegate that will process the results of the // asynchronous request. AsyncCallback callBack = new AsyncCallback(ProcessDnsInformation); // The following method is called when each asynchronous operation completes. static void ProcessDnsInformation(IAsyncResult result) { ...
