.net - 如何在异步方法中使用 AcceptTcpClient

Question

我正在使用使用 TcpListener 的 C++/CLI 制作一个小程序，我知道 AcceptTcpClient 是一种同步方法，它会阻塞 UI 线程。我如何调用此方法才能使其不会阻塞我的 UI？这是我的代码:

TcpClient^ client = server->AcceptTcpClient();
sendConsoleResult( "Connected to Client, waiting for for instructions..." );
data = nullptr;
// Get a stream Object* for reading and writing
NetworkStream^ stream = client->GetStream();
Int32 i;
// Loop to receive all the data sent by the client.
while ( i = stream->Read( bytes, 0, bytes->Length ))
{
    // Translate data bytes to a ASCII String*.
    data = Encoding::ASCII->GetString( bytes, 0, i );
    sendConsoleResult("[RECEIVED]: "+ data);
    // Process the data then send to command processing module
    data = data->ToUpper();
    response = commandProcess(data)->ToUpper();
    array<Byte>^msg = Encoding::ASCII->GetBytes( response );
    // Send back a response.
    stream->Write( msg, 0, msg->Length );
    sendConsoleResult("[RESPONSE]: " + response);
}

切换到使用 TcpListener.BeginAcceptTcpClient , 以及使用 NetworkStream.BeginRead .这将使您的整个操作异步进行，并且不会阻塞您的用户界面线程。
