如何使用Html Agility Pack超时请求

using System;
using System.Net.Http;
using HtmlAgilityPack;

class Program
{
    static void Main(string[] args)
    {
        string url = "https://www.example.com";
        int timeout = 5000; // 设置超时时间为5秒

        var httpClient = new HttpClient();
        httpClient.Timeout = TimeSpan.FromMilliseconds(timeout);

        var web = new HtmlWeb();
        web.UseCookies = false;
        web.PreRequest = request =>
        {
            request.Proxy = null;
            request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3";
            request.Timeout = timeout;
            return true;
        };

        HtmlDocument doc = web.Load(url);

        // 处理HTML文档
        // ...
    }
}
