How to: Export Metadata from Service Endpoints

1. Create a new Visual Studio Console App Project. Add the code shown in the following steps in the generated Program.cs file within the main() method.

2. Create a WsdlExporter.

   C#

   VB

   Copy

   WsdlExporter exporter = new WsdlExporter();
   
   

3. Set the PolicyVersion property to one of the values from the PolicyVersion enumeration. This sample sets the value to Policy15 which corresponds to WS-Policy 1.5.

   C#

   VB

   Copy

   exporter.PolicyVersion = PolicyVersion.Policy15;
   
   

4. Create an array of ServiceEndpoint objects.

   C#

   VB

   Copy

   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"));
   
   

5. Export metadata for each service endpoint.

   C#

   VB

   Copy

   // Export all endpoints for each endpoint in collection.
   foreach (ServiceEndpoint endpoint in myServiceEndpoints)
   {
       exporter.ExportEndpoint(endpoint);
   }
   
   

6. Check to make sure no errors occurred during the export process and retrieve the metadata.

   C#

   VB

   Copy

   // If there are no errors, get the documents.
   MetadataSet metadataDocs = null;
   if (exporter.Errors.Count != 0)
   {
       metadataDocs = exporter.GetGeneratedMetadata();
   }
   
   

7. You can now use the metadata, such as write it to a file by calling the WriteTo method.

The following is the full code listing for this example.

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();
            }
        }
    }
}

When compiling Program.cs reference System.ServiceModel.dll.
