如何使用HttpWebRequest获取数据

using System;
using System.IO;
using System.Net;

class Program
{
    static void Main()
    {
        // 创建HttpWebRequest对象
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://example.com/api/data");

        // 设置请求方法和其他属性
        request.Method = "GET";
        request.ContentType = "application/json";
        request.UserAgent = "MyApp/1.0";

        // 发送请求并获取响应
        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
        {
            // 处理响应数据
            using (Stream stream = response.GetResponseStream())
            {
                StreamReader reader = new StreamReader(stream);
                string responseData = reader.ReadToEnd();
                Console.WriteLine(responseData);
            }
        }
    }
}
