Question

我为Soap XML请求编写了c＃代码，我已验证此代码生成XML类。

我的问题是如何使用c＃代码发送请求和接收响应。

请善待我的简单或基本错误，因为我是XML的新手，但我们非常感谢您的帮助。

SOAP XML请求：

请告诉我如何使用上面的代码发送请求并从WCF服务接收响应。

即使我添加了wsdl引用，但我不知道如何在下面的行中传递XmlElement []。

serviceReference.getDetail（ref XmlElement [] Any）;

这是Reference class中的一个方法。

    [System.ServiceModel.ServiceContractAttribute(Namespace="http://www.domainname.com/whatever/webname/schema/ce/v2.2/NameContractServic" +
        "e", ConfigurationName="TestingPension.NameContractServiceDetailType")]
    public interface NameContractServiceDetailType {

        // CODEGEN: Generating message contract since the wrapper namespace (http://www.domainname.com/schema/ce/v2.2/NameContractRequest) of message getDetailRequest does not match the default value (http://www.domainname.com/name/name/schema/ce/v2.2/NameContractService)

        [System.ServiceModel.XmlSerializerFormatAttribute(SupportFaults=true)]
        SoapReqResWebApplication.TestingPension.getDetailResponse getDetail(SoapReqResWebApplication.TestingPension.getDetailRequest request);
    }

    public partial class getDetailRequest {

        [System.Xml.Serialization.XmlAnyElementAttribute()]
        public System.Xml.XmlElement[] Any;

        public getDetailRequest() {
        }

        public getDetailRequest(System.Xml.XmlElement[] Any) {
            this.Any = Any;
        }
    }

@CodeCaster 我尝试了你的代码：   var documentToSend = new XmlDocument（）;             //// TODO：添加你喜欢的所有元素
              使用（XmlTextWriter xmlRequestWriter = new XmlTextWriter（@“C：/Unipass/Request.xml”，Encoding.UTF8））               {                   xmlRequestWriter.WriteStartDocument（）;                   xmlRequestWriter.WriteStartElement（ “CE：消息”）;                   xmlRequestWriter.WriteEndElement（）;                   xmlRequestWriter.WriteEndDocument（）;                   xmlRequestWriter.Flush（）;                   documentToSend.Save（xmlRequestWriter）;                   ////创建一个以根消息节点为唯一元素的数组。                   var xmlToSend = new XmlElement [] {documentToSend.DocumentElement}; // xmlToSend = null
              } 我可能完全错了，请你告诉我为什么xmlToSend为空。

Answer 1

您似乎正在手动编写代码以将消息序列化为SOAP / XML。 SOAP请求示例是一个实际的实例文档而不是WSDL，是吗？这是WCF为您做的事情之一 - 您不需要生成自己的SOAP消息。

在WCF中，您将关注要传输的对象类型以及要支持的操作。然后WCF为您完成所有繁重的SOAP序列化。这是WCF的主要观点。

很难从您的示例SOAP消息中解读出您正在尝试做什么，所以我建议您查看一个简单的WCF示例，比如说

http://msdn.microsoft.com/en-us/library/vstudio/ms751514(v=vs.90).aspx

使用wsHttpBinding或basicHttpBinding（这些是WCF中的SOAP绑定）获取一个简单的并运行。然后使用Fiddler或类似工具捕获HTTP请求，看看WCF在SOAP信封生成方面为您做了什么。

然后，您应该能够将其转换为您自己的案例。

Answer 2

似乎WCF的代理生成器无法从提供的WSDL / XSD创建类，因为生成的方法签名是getDetailRequest(System.Xml.XmlElement[] Any)。像SoapUI这样的工具对WSDL的说法是什么？

解决此问题的方法是确实手动生成消息，该消息只是<ce:message>..</ce:message>块。当您调用服务方法时，WCF会将其包装在适当的SOAP信封中。

你必须在XmlDocument课程中玩一下，但我认为这样的事情会这样做：

// Create an XmlDocument and fill it
var documentToSend = new XmlDocument();

// TODO: add all elements you like

// Create an array with the root message node as only element.
var xmlToSend = new XmlElement[] { documentToSend.DocumentElement };

// Call the service.
var response = serviceReference.getDetail(xmlToSend);

另一种方法是在C＃中手动重新创建请求类，并在发送请求时将其实例填充并序列化为XML。最终的方法是修复XML，以便添加服务引用（SvcUtil）可以从服务的元数据中生成类。

对于您的编辑，您不是将XML元素编写到documentToSend，而是将它们写入您的文件。
