IWsdlImportExtension.ImportContract Method
Called when importing a contract.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Parameters
- importer
- Type: System.ServiceModel.Description.WsdlImporter
The importer.
- context
- Type: System.ServiceModel.Description.WsdlContractConversionContext
The import context to be modified.
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.
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.
