Writes custom Web Services Description Language (WSDL) elements into the generated WSDL for an endpoint.

public:
 void ExportEndpoint(System::ServiceModel::Description::WsdlExporter ^ exporter, System::ServiceModel::Description::WsdlEndpointConversionContext ^ context);

public void ExportEndpoint (System.ServiceModel.Description.WsdlExporter exporter, System.ServiceModel.Description.WsdlEndpointConversionContext context);

abstract member ExportEndpoint : System.ServiceModel.Description.WsdlExporter * System.ServiceModel.Description.WsdlEndpointConversionContext -> unit

Public Sub ExportEndpoint (exporter As WsdlExporter, context As WsdlEndpointConversionContext)

Parameters

exporter: WsdlExporter

The WsdlExporter that exports the endpoint information.

context: WsdlEndpointConversionContext

Provides mappings from exported WSDL elements to the endpoint description.

Examples

The following code example shows an IWsdlExportExtension that adds custom documentation attributes to the WSDL file as WSDL annotations.

public void ExportContract(WsdlExporter exporter, WsdlContractConversionContext context)
{

Console.WriteLine("Inside ExportContract");
if (context.Contract != null)
{
    // Inside this block it is the contract-level comment attribute.
    // This.Text returns the string for the contract attribute.
    // Set the doc element; if this isn't done first, there is no XmlElement in the
    // DocumentElement property.
    context.WsdlPortType.Documentation = string.Empty;
    // Contract comments.
    XmlDocument owner = context.WsdlPortType.DocumentationElement.OwnerDocument;
    XmlElement summaryElement = Formatter.CreateSummaryElement(owner, this.Text);
    context.WsdlPortType.DocumentationElement.AppendChild(summaryElement);

    foreach (OperationDescription op in context.Contract.Operations)
    {
        Operation operation = context.GetOperation(op);
        object[] opAttrs = op.SyncMethod.GetCustomAttributes(typeof(WsdlDocumentationAttribute), false);
        if (opAttrs.Length == 1)
        {
            string opComment = ((WsdlDocumentationAttribute)opAttrs[0]).Text;

            // This.Text returns the string for the operation-level attributes.
            // Set the doc element; if this isn't done first, there is no XmlElement in the
            // DocumentElement property.
            operation.Documentation = String.Empty;

            // Operation C# triple comments.
            XmlDocument opOwner = operation.DocumentationElement.OwnerDocument;
            XmlElement newSummaryElement = Formatter.CreateSummaryElement(opOwner, opComment);
            operation.DocumentationElement.AppendChild(newSummaryElement);

            // Get returns information
            ParameterInfo returnValue = op.SyncMethod.ReturnParameter;
            object[] returnAttrs = returnValue.GetCustomAttributes(typeof(WsdlParameterDocumentationAttribute), false);
            if (returnAttrs.Length == 1)
            {
                // <returns>text.</returns>
                XmlElement returnsElement =
                  Formatter.CreateReturnsElement(
                    opOwner,
                    ((WsdlParameterDocumentationAttribute)returnAttrs[0]).ParamComment
                  );
                operation.DocumentationElement.AppendChild(returnsElement);
            }

            // Get parameter information.
            ParameterInfo[] args = op.SyncMethod.GetParameters();
            for (int i = 0; i < args.Length; i++)
            {
                object[] docAttrs
                  = args[i].GetCustomAttributes(typeof(WsdlParameterDocumentationAttribute), false);
                if (docAttrs.Length != 0)
                {
                    // <param name="Int1">Text.</param>
                    XmlElement newParamElement = opOwner.CreateElement("param");
                    XmlAttribute paramName = opOwner.CreateAttribute("name");
                    paramName.Value = args[i].Name;
                    newParamElement.InnerText
                      = ((WsdlParameterDocumentationAttribute)docAttrs[0]).ParamComment;
                    newParamElement.Attributes.Append(paramName);
                    operation.DocumentationElement.AppendChild(newParamElement);
                }
            }
        }
    }
}

Remarks

Implement the ExportEndpoint method to modify the WSDL exported for an endpoint. This method is called after the contract has been exported by ExportContract.
