LoadXML 添加参数

Question

我正在做 LoadXML，但我需要从表单中添加一个字段但我不能，

    XmlDocument soapEnvelopeDocument = new XmlDocument();
soapEnvelopeDocument.LoadXml(
    @"<?xml version=""1.0"" encoding=""utf-8""?>
    <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
        <soap:Body>
            <Servis5001>
                <Kodu>abcdefg</Kodu>
                <Sifre>123456789</Sifre>
                <HesKodu>TXBHesKodu.Text</HesKodu>
            </Servis5001>
        </soap:Body>
    </soap:Envelope>");
 
return soapEnvelopeDocument;

我需要将表单中的TXBHESKodu.Text 添加到此处的<HesKodu> 字段中。 我想我无法将高引号添加到文件中。

你能告诉我怎么做吗？

Answer 1

您可以通过以下两种方式做到这一点。第一个是最简单的。只需使用这样的字符串格式（注意 @ 符号之前的 $ 符号）：

XmlDocument soapEnvelopeDocument = new XmlDocument();
            soapEnvelopeDocument.LoadXml(
                $@"<?xml version=""1.0"" encoding=""utf-8""?>
                    <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
                        <soap:Body>
                            <Servis5001>
                                <Kodu>abcdefg</Kodu>
                                <Sifre>123456789</Sifre>
                                <HesKodu>{TXBHesKodu.Text}</HesKodu>
                            </Servis5001>
                        </soap:Body>
                    </soap:Envelope>");

第二种方法使用 XML Dom 将文本添加到元素中。我们使用 XPath 语法查找元素：

var xmlDocument = GetXmlDocument(@"<?xml version=""1.0"" encoding=""utf-8""?>
                    <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
                        <soap:Body>
                            <Servis5001>
                                <Kodu>abcdefg</Kodu>
                                <Sifre>123456789</Sifre>
                                <HesKodu></HesKodu>
                            </Servis5001>
                        </soap:Body>
                    </soap:Envelope>");

            XmlNode HesKodu = xmlDocument.SelectSingleNode("//Servis5001/HesKodu");

            HesKodu.InnerText = TXBHesKodu.Text;

最好让 Visual Studio 为您处理所有 SOAP 内容。看一下添加对 SOAP Web 服务引用的引用（右键单击项目并添加 => Web 服务引用）。您只需在最后输入带有 ?wsdl 的 url，它就会生成使用 Web 服务所需的一切。

您也可以在网络浏览器中使用该网址。如果您有权访问该服务，您只需在地址栏中输入 url，然后按 Enter。它应该为您提供服务的描述以及如何使用它。

当我想添加 TXT HesKodu.Text 时方法使用错误

private static XmlDocument CreateSoapEnvelope()
        {
            XmlDocument soapEnvelopeDocument = new XmlDocument();
            soapEnvelopeDocument.LoadXml(
                $@"<?xml version=""1.0"" encoding=""utf-8""?>
                    <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
                        <soap:Body>
                            <Servis5001>
                                <Kodu>abcdef</Kodu>
                                <Sifre>abcdef</Sifre>
                                <HesKodu>{TXBHesKodu.Text}</HesKodu>
                            </Servis5001>
                        </soap:Body>
                    </soap:Envelope>");

            return soapEnvelopeDocument;
        }

SOAP 不管我用什么我的博客都是代码如下，如果你想看的话也许可以

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void BTNSorgula_Click(object sender, EventArgs e)
        {
            var _url = "https://kpsoda.tobb.org.tr/hesservis.php?wsdl";

            // begin async call to web request.
            IAsyncResult asyncResult = webRequest.BeginGetResponse(null, null);

            // suspend this thread until call is complete. You might want to
            // do something usefull here like update your UI.

            // get the response from the completed web request.
            string soapResult;
            using (WebResponse webResponse = webRequest.EndGetResponse(asyncResult))
            {
                using (StreamReader rd = new StreamReader(webResponse.GetResponseStream()))
                {

                    soapResult = rd.ReadToEnd();
                }
                result = soapResult;
                Console.Write(soapResult);
            }

        }

        private static HttpWebRequest CreateWebRequest(string url, string action)

            webRequest.Headers.Add("SOAPAction", action);
            webRequest.ContentType = "text/xml;charset=\"utf-8\"";
            webRequest.Accept = "text/xml";
            webRequest.Method = "POST";
            return webRequest;
        }

        private static XmlDocument CreateSoapEnvelope()
        {
            XmlDocument soapEnvelopeDocument = new XmlDocument();
            soapEnvelopeDocument.LoadXml(

                                <Kodu>abcdef</Kodu>
                                <Sifre>abcdef</Sifre>
                                <HesKodu>{TXBHesKodu.Text}</HesKodu>
                            </Servis5001>
                        </soap:Body>
                    </soap:Envelope>");

            return soapEnvelopeDocument;
        }

        private static void InsertSoapEnvelopeIntoWebRequest(XmlDocument soapEnvelopeXml, HttpWebRequest webRequest)
        {
            using (Stream stream = webRequest.GetRequestStream())
            {
                soapEnvelopeXml.Save(stream);
            }
        }
    }
}

我也尝试了服务引用流程，但我不知道如何请求

string Kodu = "Kodu";
string Sifre = "Sifre";
string HesKodu = "HesKodu";

TOBBHesKoduSorgulamaServices.Servis5001Request S5001R = new TOBBHesKoduSorgulamaServices.Servis5001Request();
S5001R.Kodu = Kodu;
S5001R.Sifre = Sifre;
S5001R.HesKodu = HesKodu;

TOBBHesKoduSorgulamaServices.Servis5001Response S5001Response = ?

哪一个适合我？ 期待您的支持，辛苦了……
