如何创建SOAP请求C#

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

class Program
{
    static void Main(string[] args)
    {
        // 创建SOAP请求的XML结构
        string soapRequest = @"<?xml version=""1.0"" encoding=""utf-8""?>
                                <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
                                    <soap:Body>
                                        <Request xmlns=""http://example.com/"">
                                            <Parameter1>Value1</Parameter1>
                                            <Parameter2>Value2</Parameter2>
                                        </Request>
                                    </soap:Body>
                                </soap:Envelope>";

        // 创建HTTP请求
        HttpWebRequest httpRequest = (HttpWebRequest)WebRequest.Create("http://example.com/soap-endpoint");
        httpRequest.Method = "POST";
        httpRequest.ContentType = "text/xml";

        // 将SOAP请求写入请求流中
        using (Stream stream = httpRequest.GetRequestStream())
        {
            byte[] data = Encoding.UTF8.GetBytes(soapRequest);
            stream.Write(data, 0, data.Length);
        }

        // 发送请求并获取响应
        HttpWebResponse httpResponse = (HttpWebResponse)httpRequest.GetResponse();
        using (StreamReader streamReader = new StreamReader(httpResponse.GetResponseStream(), Encoding.UTF8))
        {
            string soapResponse = streamReader.ReadToEnd();
            // 处理SOAP响应
            Console.WriteLine(soapResponse);
        }
    }
}
