WebSocket异步发送和接收数据(使用NuGet websocket-client)

using System;
using System.Net.WebSockets;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        using var client = new ClientWebSocket();
        Uri serverUri = new Uri("wss://example.com/socket");
        await client.ConnectAsync(serverUri, CancellationToken.None);

        // 发送数据
        string message = "Hello, WebSocket!";
        byte[] buffer = Encoding.UTF8.GetBytes(message);
        await client.SendAsync(new ArraySegment<byte>(buffer), WebSocketMessageType.Text, true, CancellationToken.None);

        // 接收数据
        var result = await client.ReceiveAsync(new ArraySegment<byte>(new byte[1024]), CancellationToken.None);
        string receivedMessage = Encoding.UTF8.GetString(result.Buffer, 0, result.Count);
        Console.WriteLine("Received: " + receivedMessage);

        // 关闭连接
        await client.CloseAsync(WebSocketCloseStatus.NormalClosure, "", CancellationToken.None);
    }
}
