WsdlExporter Class

Converts service, contract, and endpoint information into metadata documents.

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

public class WsdlExporter : MetadataExporter

Use the WsdlExporter class to transform ContractDescription or ServiceEndpoint objects into metadata represented by MetadataSection objects.

The WsdlExporter is used in a three-step process.

  1. Call the ExportContract, ExportEndpoint, or ExportEndpoints method, passing the appropriate parameters.

  2. Determine whether there are any export errors by checking the base Errors property.

  3. If there are no errors, use the GetGeneratedMetadata to get a collection of MetadataSection objects or get more specific versions of the metadata using the GeneratedWsdlDocuments or GeneratedXmlSchemas properties.

You can support exporting custom WSDL extensions by implementing the IWsdlExportExtension interface and custom policy assertions by implementing the IPolicyExportExtension interface. For details, see the documentation for those interfaces.

NoteNote:

The WsdlExporter can only be used to export metadata from ContractDescription instances that contain Common Language Runtime (CLR) type information, such as a ContractDescription instance created using the ContractDescription.GetContract method or created as part of the ServiceDescription for a ServiceHost instance. You cannot use the WsdlExporter to export metadata from ContractDescription instances imported from service metadata or constructed without type information.

The following code example shows how to use the ExportEndpoint method to generate a set of MetadataSection objects from the endpoints in a collection of ServiceEndpoint objects called myServiceEndpoints.

using System;
using System.ServiceModel;
using System.ServiceModel.Description;

namespace WsdlExporterSample
{
    class Program
    {
        static void Main(string[] args)
        {
            WsdlExporter exporter = new WsdlExporter();
            exporter.PolicyVersion = PolicyVersion.Policy15;

            ServiceEndpoint [] myServiceEndpoints = new ServiceEndpoint[2];
            ContractDescription myDescription = new ContractDescription ("myContract");
            myServiceEndpoints[0] = new ServiceEndpoint(myDescription,new BasicHttpBinding(),new EndpointAddress("http://localhost/myservice"));
            myServiceEndpoints[1] = new ServiceEndpoint(myDescription,new BasicHttpBinding(),new EndpointAddress("http://localhost/myservice"));

            // Export all endpoints for each endpoint in collection. 
            foreach (ServiceEndpoint endpoint in myServiceEndpoints)
            {
                exporter.ExportEndpoint(endpoint);
            }
            // If there are no errors, get the documents.
            MetadataSet metadataDocs = null;
            if (exporter.Errors.Count != 0)
            {
                metadataDocs = exporter.GetGeneratedMetadata();
            }
        }
    }
}
