在C#中使用Netty,通常會使用其C#版本的實現庫,如DotNetty。以下是使用DotNetty的基本方法:
引入DotNetty庫: 首先需要在項目中引入DotNetty的NuGet包。可以在Visual Studio中搜索并安裝DotNetty的NuGet包。
創建服務器端: 使用DotNetty創建服務器端需要定義一個Bootstrap對象,并設置相應的參數,如端口號、處理器等。然后調用Bootstrap的BindAsync方法啟動服務器。
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是自定義的處理器,用于處理收到的數據。通過設置處理器,可以實現具體業務邏輯。
總的來說,使用Netty的C#版本DotNetty,通過創建Bootstrap對象來定義服務器端和客戶端,設置相應參數和處理器,然后啟動服務器或連接服務器,從而實現網絡通信功能。
