在C#中使用Netty,通常会使用其C#版本的实现库,如DotNetty。以下是使用DotNetty的基本方法:
引入DotNetty库: 首先需要在项目中引入DotNetty的NuGet包。可以在Visual Studio中搜索并安装DotNetty的NuGet包。
创建服务器端: 使用DotNetty创建服务器端需要定义一个Bootstrap对象,并设置相应的参数,如端口号、处理器等。然后调用Bootstrap的BindAsync方法启动服务器。
var bossGroup = new MultithreadEventLoopGroup(1);
var workerGroup = new MultithreadEventLoopGroup();
try
{
var bootstrap = new ServerBootstrap()
.Group(bossGroup, workerGroup)
.Channel<TcpServerSocketChannel>()
.ChildHandler(new ActionChannelInitializer<IChannel>(channel =>
{
var pipeline = channel.Pipeline;
pipeline.AddLast(new LoggingHandler("SRV-CONN"));
pipeline.AddLast(new ServerHandler());
}));
var channel = await bootstrap.BindAsync(new IPEndPoint(IPAddress.Any, 8080));
Console.WriteLine($"Server started on {channel.LocalAddress}");
await channel.CloseCompletion;
}
finally
{
await Task.WhenAll(
bossGroup.ShutdownGracefullyAsync(TimeSpan.FromMilliseconds(100), TimeSpan.FromSeconds(1)),
workerGroup.ShutdownGracefullyAsync(TimeSpan.FromMilliseconds(100), TimeSpan.FromSeconds(1))
);
}
var group = new MultithreadEventLoopGroup();
try
{
var bootstrap = new Bootstrap()
.Group(group)
.Channel<TcpSocketChannel>()
.Handler(new ActionChannelInitializer<IChannel>(channel =>
{
var pipeline = channel.Pipeline;
pipeline.AddLast(new LoggingHandler("CLI-CONN"));
pipeline.AddLast(new ClientHandler());
}));
var channel = await bootstrap.ConnectAsync(new IPEndPoint(IPAddress.Loopback, 8080));
Console.WriteLine($"Client connected to {channel.RemoteAddress}");
await channel.CloseCompletion;
}
finally
{
await group.ShutdownGracefullyAsync(TimeSpan.FromMilliseconds(100), TimeSpan.FromSeconds(1));
}
在以上示例中,ServerHandler和ClientHandler是自定义的处理器,用于处理收到的数据。通过设置处理器,可以实现具体业务逻辑。
总的来说,使用Netty的C#版本DotNetty,通过创建Bootstrap对象来定义服务器端和客户端,设置相应参数和处理器,然后启动服务器或连接服务器,从而实现网络通信功能。
