来自WSDL的详细ServiceDescription / Proxy

我使用ServiceDescription / ServiceDescriptionImporter类来动态调用Web服务。我想深入研究WSDL描述并获取

1)每个Web方法的参数信息

2)所有Web方法的每个参数的实际类型/组成(即,如果WebMethod将某些复杂类型作为参数,我需要知道它组成的原语/其他类型,如果可能的话)< / p>

以下是动态调用的代码:

    public static object CallWebService(string webServiceAsmx, string serviceName, string methodName, object[] args = null)
    {
        WebClient client = new WebClient();

        Stream stream = client.OpenRead(webServiceAsmx + "?wsdl");
        ServiceDescription description = ServiceDescription.Read(stream);
        ServiceDescriptionImporter importer = new ServiceDescriptionImporter();

        importer.ProtocolName = "Soap12";
        importer.AddServiceDescription(description, null, null);
        importer.Style = ServiceDescriptionImportStyle.Client;
        importer.CodeGenerationOptions = CodeGenerationOptions.GenerateProperties;

我已经能够找到一些基本信息,如方法名称,参数信息,但我需要更深入的分析。例如,我需要访问Wsdl.exe在代理类中生成的基本上所有信息,但我不想运行Wsdl.exe,只是动态发现信息。对于每个方法,我需要知道它的返回类型是由什么组成的,它的参数是由什么组成的等等。我知道它在WSDL中只是不确定如何以编程方式提取它。以下是我一直在探索的一些课程:

ServiceDescription.Description 
ServiceDescription.Messages
ServiceDescription.Types

看来很多人都空了?

我进一步说,这是我试图遍历的xml架构(WSDL):

- <s:complexType name="Session">
- <s:complexContent mixed="false">
- <s:extension base="tns:EntityObject">
 - <s:sequence>
    <s:element minOccurs="0" maxOccurs="1" name="Name" type="s:string" /> 
    <s:element minOccurs="0" maxOccurs="1" name="Host" type="s:string" /> 
    <s:element minOccurs="0" maxOccurs="1" name="SessionType" type="s:string" /> 
    <s:element minOccurs="1" maxOccurs="1" name="LoginTime" type="s:dateTime" /> 
    <s:element minOccurs="1" maxOccurs="1" name="LogoutTime" type="s:dateTime" /> 
   </s:sequence>
  </s:extension>
 </s:complexContent>
   </s:complexType>

这是遍历的代码:

 foreach (System.Xml.Schema.XmlSchemaComplexType item in xmlSchema.SchemaTypes.Values)
        {
            if (item != null)
            {
                System.Xml.Schema.XmlSchemaParticle particle = item.Particle;
                System.Xml.Schema.XmlSchemaSequence sequence = particle as System.Xml.Schema.XmlSchemaSequence;

                if (sequence != null)
                {
                    foreach (System.Xml.Schema.XmlSchemaElement childElement in sequence.Items)
                    {
                        string name = childElement.Name;
                        string type = childElement.SchemaTypeName.Name;

                        Console.WriteLine(name + " " + type); 
                    }
                }
            }

这让我更进一步,但不是获得ComplexType的complexContent。在控制台中生成以下输出:

如果有人有类似的问题,我就是这样做的:

foreach (System.Xml.Schema.XmlSchemaComplexType item in xmlSchema.SchemaTypes.Values)
        {
            ComplexType cType = new ComplexType(item.Name);

            System.Xml.Schema.XmlSchemaContentModel model = item.ContentModel;
            System.Xml.Schema.XmlSchemaComplexContent complex = model as System.Xml.Schema.XmlSchemaComplexContent;

            if (complex != null)
            {
                System.Xml.Schema.XmlSchemaComplexContentExtension extension = complex.Content as System.Xml.Schema.XmlSchemaComplexContentExtension;
                System.Xml.Schema.XmlSchemaParticle particle = extension.Particle;
                System.Xml.Schema.XmlSchemaSequence sequence = particle as System.Xml.Schema.XmlSchemaSequence;

                if (sequence != null)
                {
                    List<SimpleType> primitives = new List<SimpleType>(); 

                    foreach (System.Xml.Schema.XmlSchemaElement childElement in sequence.Items)
                    {
                        string name = childElement.Name;
                        string type = childElement.SchemaTypeName.Name;
                        cType.Primitives.Add(new SimpleType(name, type));
                    }

                    if (cType.Name == parameter.Type || "ArrayOf" + cType.Name == parameter.Type)
                    {
                        descriptions.Add(new ComplexParameter(cType, item.Name));
                    }
                }
            }
        }

这与你所做的非常相似WebServiceInfo它返回带有信息的自定义对象。 (如果我理解你的问题和博客足够好)
