将CURL调用转换为C#

using System;
using System.Net.Http;

class Program
{
    static async System.Threading.Tasks.Task Main(string[] args)
    {
        using (HttpClient client = new HttpClient())
        {
            // 设置请求的URL
            string url = "https://api.example.com/endpoint";

            // 创建一个HttpRequestMessage对象
            HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, url);

            // 添加请求头信息
            request.Headers.Add("User-Agent", "Mozilla/5.0");

            // 发送请求并获取响应
            HttpResponseMessage response = await client.SendAsync(request);

            // 读取响应内容
            string responseBody = await response.Content.ReadAsStringAsync();

            // 输出响应内容
            Console.WriteLine(responseBody);
        }
    }
}
