using System.IO;
using System.Net;

class Program
{
    static void Main(string[] args)
    {
        string url = "http://example.com/api";
        string postData = "param1=value1&param2=value2";

        // 创建HttpWebRequest对象
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";

        // 将POST数据写入请求流
        using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
        {
            writer.Write(postData);
        }

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