c# websocketserver怎样简化代码-乐工具技术知识

要简化C# WebSocket服务器的代码，可以使用一些现成的库和框架，例如Microsoft.AspNetCore.Http.WebSocket。以下是一个简单的示例，展示了如何使用ASP.NET Core创建一个基本的WebSocket服务器：

首先，确保已安装以下NuGet包：

Microsoft.AspNetCore.Http.Abstractions
Microsoft.AspNetCore.Http.Core
Microsoft.AspNetCore.WebSockets

创建一个名为Startup.cs的文件，并添加以下内容：

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using System.Threading.Tasks;

namespace WebSocketServer
{
    public class Startup
    {
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllers();
            services.AddEndpointsApiExplorer();
            services.AddSwaggerGen();
        }

        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
                app.UseSwagger();
                app.UseSwaggerUI();
            }

            app.UseRouting();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
                endpoints.MapWebSocket("/ws", async (client, context) =>
                {
                    await Echo(client, context);
                });
            });
        }

        private async Task Echo(WebSocketClient client, WebSocketContext context)
        {
            byte[] buffer = new byte[1024 * 4];
            WebSocketReceiveResult result;

            do
            {
                result = await client.ReceiveAsync(new ArraySegment(buffer), CancellationToken.None);
                if (result.CloseStatus != null)
                {
                    break;
                }

                await client.SendAsync(new ArraySegment(buffer, 0, result.Count), result.CloseStatus.Value, CancellationToken.None);
            }
            while (!result.CloseStatus.HasValue);

            await client.CloseAsync(result.CloseStatus.Value, result.CloseStatusDescription, CancellationToken.None);
        }
    }
}

这个示例中，我们创建了一个简单的WebSocket服务器，监听/ws路径。当客户端连接到该路径时，服务器会将接收到的消息原样发送回客户端。

创建一个名为Program.cs的文件，并添加以下内容：

using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Hosting;

namespace WebSocketServer
{
    public class Program
    {
        public static void Main(string[] args)
        {
            CreateHostBuilder(args).Build().Run();
        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup();
                });
    }
}
