如何使用.NET核心2.0连接服务使用web服务

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

namespace WebServiceExample
{
    class Program
    {
        static async Task Main(string[] args)
        {
            // 创建HttpClient实例
            using (var httpClient = new HttpClient())
            {
                // 设置Web服务的地址
                string serviceUrl = "http://example.com/your-web-service";

                // 构建SOAP请求的XML内容
                string soapRequest = @"
                    <soap:Envelope xmlns:soap='http://www.w3.org/2003/05/soap-envelope' xmlns:web='http://example.com/your-web-service'>
                        <soap:Header/>
                        <soap:Body>
                            <web:YourWebServiceMethod>
                                <web:Parameter1>Value1</web:Parameter1>
                                <web:Parameter2>Value2</web:Parameter2>
                            </web:YourWebServiceMethod>
                        </soap:Body>
                    </soap:Envelope>";

                // 创建HttpContent对象，用于发送SOAP请求
                var httpContent = new StringContent(soapRequest, System.Text.Encoding.UTF8, "application/soap+xml");

                // 发送POST请求到Web服务
                var response = await httpClient.PostAsync(serviceUrl, httpContent);

                // 读取响应内容
                var responseContent = await response.Content.ReadAsStringAsync();

                // 解析响应XML
                var soapResponse = XDocument.Parse(responseContent);

                // 处理响应数据
                // ...
            }
        }
    }
}
