异步客户端套接字，增加缓冲区大小

我已经实现了一个与本例极其相似的异步客户端套接字。为什么我不能显著增加这个缓冲区的大小？在这个例子中，缓冲区的大小是256字节。在许多的情况下，我的应用程序最终接收到的数据是5000++字节的数据。我应该增加缓冲区大小吗？有什么理由不应该增加缓冲区大小吗？

每隔很长一段时间，我就会遇到一些问题，比如数据出现故障或区块丢失（具体是哪一个尚待确认）。例如，有一次我收到一些损坏的数据，看起来像这个

Slice Id="0" layotartX='100'

在我的数据中不存在名为laystartX的属性，它应该说layout=。。。但是布局被截断了，其他数据随后被附加到它上面。我数了数字节，注意到它被截断为256字节，恰好是我的缓冲区大小。增加我的缓冲区大小很可能会防止这个问题的发生（数据无序？？）。无论如何，正如第一段所述，我只是想问是否有任何理由不应该将缓冲区大小增加到5000字节甚至10000字节。

添加一些代码下面是我修改后的ReceiveCallback函数（其他类请参阅上面链接的示例代码。当ReceiveCallback接收到数据时，它会调用我在下面发布的"ReceiveSomeData"函数。由于某些原因，我每隔一段时间就会出现数据无序或丢失的情况。"ReceiveSome data"函数位于一个名为"MyChitterChatter"的类中"ReceiveCallback"函数位于名为"AsyncClient"的类中。因此，当您看到ReceiveSomeData函数锁定"this"时，它就是锁定MyChitterChatter类。有没有我的问题可以通过撒谎？

    private static void ReceiveCallback( IAsyncResult ar )
    {
        AppDelegate appDel = (AppDelegate)UIApplication.SharedApplication.Delegate;
        try {
            // Retrieve the state object and the client socket 
            // from the asynchronous state object.
            StateObject state = (StateObject) ar.AsyncState;
            Socket client = state.workSocket;
            // Read data from the remote device.
            int bytesRead = client.EndReceive(ar);
            if (bytesRead > 0) {
                // There might be more data, so store the data received so far.
                string stuffWeReceived = Encoding.ASCII.GetString(state.buffer,0,bytesRead);
                string debugString = "~~~~~ReceiveCallback~~~~~~ " + stuffWeReceived + " len = " + stuffWeReceived.Length + " bytesRead = " + bytesRead;
                Console.WriteLine(debugString);

                // Send this data to be received
                appDel.wallInteractionScreen.ChitterChatter.ReceiveSomeData(stuffWeReceived);
                // Get the rest of the data.
                client.BeginReceive(state.buffer,0,StateObject.BufferSize,0,
                    new AsyncCallback(ReceiveCallback), state);
            } else {
                // Signal that all bytes have been received.
                receiveDone.Set();
            }
        } 
        catch (Exception e) {
            Console.WriteLine("Error in AsyncClient ReceiveCallback: ");
            Console.WriteLine(e.Message);
            Console.WriteLine(e.StackTrace);
        }
    }

    public void ReceiveSomeData ( string data )
    {
        lock(this)
        {
            DataList_New.Add(data);
            // Update the keepalive when we receive ANY data at all
            IsConnected = true;
            LastDateTime_KeepAliveReceived = DateTime.Now;
        }
    }
