IWsdlImportExtension.ImportContract Method

  • Reference

Definition

Namespace:
System.ServiceModel.Description
Assembly:
System.ServiceModel.dll

Called when importing a contract.

public:
 void ImportContract(System::ServiceModel::Description::WsdlImporter ^ importer, System::ServiceModel::Description::WsdlContractConversionContext ^ context);
public void ImportContract (System.ServiceModel.Description.WsdlImporter importer, System.ServiceModel.Description.WsdlContractConversionContext context);
abstract member ImportContract : System.ServiceModel.Description.WsdlImporter * System.ServiceModel.Description.WsdlContractConversionContext -> unit
Public Sub ImportContract (importer As WsdlImporter, context As WsdlContractConversionContext)

Parameters

importer
WsdlImporter

The importer.

context
WsdlContractConversionContext

The import context to be modified.

Examples

The following code example shows the use of IWsdlImportExtension to add an System.ServiceModel.Description.IServiceContractGenerationExtension and an System.ServiceModel.Description.IOperationContractGenerationExtension (the WsdlDocumentationImporter, in this case) to modify generated WCF client code at the interface and operation level.

  public void ImportContract(WsdlImporter importer, WsdlContractConversionContext context)
  {
Console.Write("ImportContract");
      // Contract Documentation
      if (context.WsdlPortType.Documentation != null)
      {
  context.Contract.Behaviors.Add(new WsdlDocumentationImporter(context.WsdlPortType.Documentation));
      }
      // Operation Documentation
      foreach (Operation operation in context.WsdlPortType.Operations)
      {
          if (operation.Documentation != null)
          {
              OperationDescription operationDescription = context.Contract.Operations.Find(operation.Name);
              if (operationDescription != null)
              {
      operationDescription.Behaviors.Add(new WsdlDocumentationImporter(operation.Documentation));
              }
          }
      }
  }

The following code example shows how to configure the client metadata system to use the custom IWsdlImportExtension from an application configuration file.

<system.serviceModel>
    <client>
      <endpoint 
        address="http://localhost:8000/Fibonacci" 
        binding="wsHttpBinding"
        contract="IFibonacci"
      />
      <metadata>
        <wsdlImporters>
          <extension type="Microsoft.WCF.Documentation.WsdlDocumentationImporter, WsdlDocumentation, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
        </wsdlImporters>
      </metadata>
    </client>
  </system.serviceModel>

Remarks

The ImportContract method is called when a contract is being imported. You can modify the contract or insert other exporting behaviors such as System.ServiceModel.Description.IServiceContractGenerationExtension and an System.ServiceModel.Description.IOperationContractGenerationExtension objects to modify the code that is generated for the contract.
