ServiceContractGenerator Class

The System.ServiceModel.Description.ServiceContractGenerator type generates service contract code and binding configurations from System.ServiceModel.Description.ServiceEndpoint description objects.

System.Object
  System.ServiceModel.Description.ServiceContractGenerator

Namespace:  System.ServiceModel.Description
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public class ServiceContractGenerator

The ServiceContractGenerator type exposes the following members.

  NameDescription
Public methodServiceContractGenerator()Initializes a new instance of the ServiceContractGenerator class with a new System.CodeDom.CodeCompileUnit instance.
Public methodServiceContractGenerator(CodeCompileUnit)Initializes a new instance of the ServiceContractGenerator class with the specified System.CodeDom.CodeCompileUnit instance.
Public methodServiceContractGenerator(Configuration)Initializes a new instance of the ServiceContractGenerator class with the specified System.Configuration.Configuration instance.
Public methodServiceContractGenerator(CodeCompileUnit, Configuration)Initializes a new instance of the ServiceContractGenerator class with the specified System.CodeDom.CodeCompileUnit instance and the specified System.Configuration.Configuration instance.

  NameDescription
Public propertyConfigurationGets the System.Configuration.Configuration instance that contains the generated binding configurations.
Public propertyErrorsGets a collection of System.ServiceModel.Description.MetadataConversionError objects generated when generating service contract code and endpoint configurations.
Public propertyNamespaceMappingsGets a mapping from contract description namespaces to managed namespaces that is used when generating code.
Public propertyOptionsGets or sets options for generating service contract code.
Public propertyReferencedTypesGets a mapping from contract descriptions to referenced contract types.
Public propertyTargetCompileUnitGets the target System.CodeDom.CodeCompileUnit object for generating service contract code.

  NameDescription
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGenerateBindingGenerates a binding configuration for the specified System.ServiceModel.Channels.Binding instance.
Public methodGenerateServiceContractTypeGenerates a service contract type from the specified System.ServiceModel.Description.ContractDescription instance.
Public methodGenerateServiceEndpointGenerates a service contract type and an endpoint configuration from the specified System.ServiceModel.Description.ServiceEndpoint instance.
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Use the ServiceContractGenerator to create tools or to modify the default contract generation process using an System.ServiceModel.Description.IWsdlImportExtension.

The following example shows the use of a ServiceContractGenerator to convert downloaded metadata into code.

		static void GenerateCSCodeForService(EndpointAddress metadataAddress, string outputFile)
		{
      MetadataExchangeClient mexClient = new MetadataExchangeClient(metadataAddress);
      mexClient.ResolveMetadataReferences = true;
      MetadataSet metaDocs = mexClient.GetMetadata();

			WsdlImporter importer = new WsdlImporter(metaDocs);
      ServiceContractGenerator generator = new ServiceContractGenerator();

      // Add our custom DCAnnotationSurrogate  
      // to write XSD annotations into the comments. 
      object dataContractImporter;
      XsdDataContractImporter xsdDCImporter;
      if (!importer.State.TryGetValue(typeof(XsdDataContractImporter), out dataContractImporter))
      {
        Console.WriteLine("Couldn't find the XsdDataContractImporter! Adding custom importer.");
        xsdDCImporter = new XsdDataContractImporter();
        xsdDCImporter.Options = new ImportOptions();
        importer.State.Add(typeof(XsdDataContractImporter), xsdDCImporter);
      }
      else
      {
        xsdDCImporter = (XsdDataContractImporter)dataContractImporter;
        if (xsdDCImporter.Options == null)
        {
          Console.WriteLine("There were no ImportOptions on the importer.");
          xsdDCImporter.Options = new ImportOptions();
        }
      }
      xsdDCImporter.Options.DataContractSurrogate = new DCAnnotationSurrogate();

      // Uncomment the following code if you are going to do your work programmatically rather than add  
      // the WsdlDocumentationImporters through a configuration file.  
      /*
      // The following code inserts a custom WsdlImporter without removing the other 
      // importers already in the collection.
      System.Collections.Generic.IEnumerable<IWsdlImportExtension> exts = importer.WsdlImportExtensions;
      System.Collections.Generic.List<IWsdlImportExtension> newExts 
        = new System.Collections.Generic.List<IWsdlImportExtension>();
      foreach (IWsdlImportExtension ext in exts)
      {
        Console.WriteLine("Default WSDL import extensions: {0}", ext.GetType().Name);
        newExts.Add(ext);
      }
      newExts.Add(new WsdlDocumentationImporter());
      System.Collections.Generic.IEnumerable<IPolicyImportExtension> polExts = importer.PolicyImportExtensions;
      importer = new WsdlImporter(metaDocs, polExts, newExts);
      */

      System.Collections.ObjectModel.Collection<ContractDescription> contracts 
        = importer.ImportAllContracts();
      importer.ImportAllEndpoints();
			foreach (ContractDescription contract in contracts)
			{
				generator.GenerateServiceContractType(contract);
			}
      if (generator.Errors.Count != 0)
        throw new Exception("There were errors during code compilation.");

      // Write the code dom
      System.CodeDom.Compiler.CodeGeneratorOptions options 
        = new System.CodeDom.Compiler.CodeGeneratorOptions();
			options.BracingStyle = "C";
			System.CodeDom.Compiler.CodeDomProvider codeDomProvider 
        = System.CodeDom.Compiler.CodeDomProvider.CreateProvider("C#");
			System.CodeDom.Compiler.IndentedTextWriter textWriter 
        = new System.CodeDom.Compiler.IndentedTextWriter(new System.IO.StreamWriter(outputFile));
			codeDomProvider.GenerateCodeFromCompileUnit(
        generator.TargetCompileUnit, textWriter, options
      );
			textWriter.Close();
		}
