如何将数据集作为参数传递给c#中的另一个url

using System;
using System.Net;

class Program
{
    static void Main()
    {
        // 创建HTTP请求对象
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("目标URL");
        request.Method = "POST";

        // 设置请求参数
        string dataset = "你的数据集";
        byte[] data = System.Text.Encoding.UTF8.GetBytes(dataset);
        request.ContentLength = data.Length;
        request.ContentType = "application/x-www-form-urlencoded";

        // 将数据写入请求流
        using (var stream = request.GetRequestStream())
        {
            stream.Write(data, 0, data.Length);
        }

        // 发送请求并获取响应
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        string responseString = new System.IO.StreamReader(response.GetResponseStream()).ReadToEnd();

        // 处理响应数据
        Console.WriteLine(responseString);
    }
}
