解析复杂的WSDL参数信息

我试图解析WSDL，就像这里给出的例子一样。

作者在评论中指出，该示例无法深入研究复杂的数据类型。

事实上，当我运行这个例子时，它似乎甚至不能处理简单的数据类型。

我在System.Web.Services.Description.ServiceDescription类中搜索过，该类在示例中使用，但在运行时无法找到任何实际参数或返回类型信息。 我知道我可能需要对xsd文件进行一些手动解析？

谷歌和stackoverflow似乎缺乏如何以编程方式深入研究复杂类型的完整示例，所以…我该怎么做？

这不是很好 – 但它完成了工作（希望如此;）。 我将此代码部分基于您提供的链接，然后添加一些递归来解析模式中包含的不同类型，以及内部元素及其数据类型。 这肯定没有考虑XML模式中的所有可能性，但我认为它足以说明如果需要可以增加复杂性。

我希望这有帮助！！！！

internal class Program { private static void Main(string[] args) { //Build the URL request string UriBuilder uriBuilder = new UriBuilder(@"http://digicomdev:8888/digitalOrderBroker/digitalOrderBroker.asmx"); uriBuilder.Query = "WSDL"; HttpWebRequest webRequest = (HttpWebRequest) WebRequest.Create(uriBuilder.Uri); webRequest.ContentType = "text/xml;charset=\"utf-8\""; webRequest.Method = "GET"; webRequest.Accept = "text/xml"; //Submit a web request to get the web service's WSDL ServiceDescription serviceDescription; using (WebResponse response = webRequest.GetResponse()) { using (Stream stream = response.GetResponseStream()) { serviceDescription = ServiceDescription.Read(stream); } } //Loop through the port types in the service description and list all of the //web service's operations and each operations input/output foreach (PortType portType in serviceDescription.PortTypes) { foreach (Operation operation in portType.Operations) { Console.Out.WriteLine(operation.Name); foreach (var message in operation.Messages) { if (message is OperationInput) Console.Out.WriteLine("Input Message: {0}", ((OperationInput) message).Message.Name); if (message is OperationOutput) Console.Out.WriteLine("Output Message: {0}", ((OperationOutput) message).Message.Name); foreach (Message messagePart in serviceDescription.Messages) { if (messagePart.Name != ((OperationMessage) message).Message.Name) continue; foreach (MessagePart part in messagePart.Parts) { Console.Out.WriteLine(part.Name); } } } Console.Out.WriteLine(); } } //End listing of types //Drill down into the WSDL's complex types to list out the individual schema elements //and their data types Types types = serviceDescription.Types; XmlSchema xmlSchema = types.Schemas[0]; foreach (object item in xmlSchema.Items) { XmlSchemaElement schemaElement = item as XmlSchemaElement; XmlSchemaComplexType complexType = item as XmlSchemaComplexType; if (schemaElement != null) { Console.Out.WriteLine("Schema Element: {0}", schemaElement.Name); XmlSchemaType schemaType = schemaElement.SchemaType; XmlSchemaComplexType schemaComplexType = schemaType as XmlSchemaComplexType; if (schemaComplexType != null) { XmlSchemaParticle particle = schemaComplexType.Particle; XmlSchemaSequence sequence = particle as XmlSchemaSequence; if (sequence != null) { foreach (XmlSchemaElement childElement in sequence.Items) { Console.Out.WriteLine(" Element/Type: {0}:{1}", childElement.Name, childElement.SchemaTypeName.Name); } } } } else if (complexType != null) { Console.Out.WriteLine("Complex Type: {0}", complexType.Name); OutputElements(complexType.Particle); } Console.Out.WriteLine(); } Console.Out.WriteLine(); Console.In.ReadLine(); } private static void OutputElements(XmlSchemaParticle particle) { XmlSchemaSequence sequence = particle as XmlSchemaSequence; XmlSchemaChoice choice = particle as XmlSchemaChoice; XmlSchemaAll all = particle as XmlSchemaAll; if (sequence != null) { Console.Out.WriteLine(" Sequence"); for (int i = 0; i < sequence.Items.Count; i++) { XmlSchemaElement childElement = sequence.Items[i] as XmlSchemaElement; XmlSchemaSequence innerSequence = sequence.Items[i] as XmlSchemaSequence; XmlSchemaChoice innerChoice = sequence.Items[i] as XmlSchemaChoice; XmlSchemaAll innerAll = sequence.Items[i] as XmlSchemaAll; if (childElement != null) { Console.Out.WriteLine(" Element/Type: {0}:{1}", childElement.Name, childElement.SchemaTypeName.Name); } else OutputElements(sequence.Items[i] as XmlSchemaParticle); } } else if (choice != null) { Console.Out.WriteLine(" Choice"); for (int i = 0; i < choice.Items.Count; i++) { XmlSchemaElement childElement = choice.Items[i] as XmlSchemaElement; XmlSchemaSequence innerSequence = choice.Items[i] as XmlSchemaSequence; XmlSchemaChoice innerChoice = choice.Items[i] as XmlSchemaChoice; XmlSchemaAll innerAll = choice.Items[i] as XmlSchemaAll; if (childElement != null) { Console.Out.WriteLine(" Element/Type: {0}:{1}", childElement.Name, childElement.SchemaTypeName.Name); } else OutputElements(choice.Items[i] as XmlSchemaParticle); } Console.Out.WriteLine(); } else if (all != null) { Console.Out.WriteLine(" All"); for (int i = 0; i < all.Items.Count; i++) { XmlSchemaElement childElement = all.Items[i] as XmlSchemaElement; XmlSchemaSequence innerSequence = all.Items[i] as XmlSchemaSequence; XmlSchemaChoice innerChoice = all.Items[i] as XmlSchemaChoice; XmlSchemaAll innerAll = all.Items[i] as XmlSchemaAll; if (childElement != null) { Console.Out.WriteLine(" Element/Type: {0}:{1}", childElement.Name, childElement.SchemaTypeName.Name); } else OutputElements(all.Items[i] as XmlSchemaParticle); } Console.Out.WriteLine(); } } }

你想用解析的结果做什么？ 例如，如果要将类型放入内存以便使用它们，可以使用ServiceDescription.Read和导入器来编译程序集。

您可以在此PowerShell脚本中看到此类方法的示例：
