如何将此Ajax Post请求转换为C#

using System;
using System.Net.Http;
using System.Threading.Tasks;

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

            // 构造请求参数
            var parameters = new Dictionary<string, string>
            {
                { "param1", "value1" },
                { "param2", "value2" }
            };

            // 发送POST请求
            var response = await client.PostAsync(url, new FormUrlEncodedContent(parameters));

            // 获取响应内容
            string result = await response.Content.ReadAsStringAsync();

            // 处理响应结果
            Console.WriteLine(result);
        }
    }
}
