System.ServiceModel.dll

Skriver anpassade WSDL-element (Web Services Description Language) till den genererade WSDL:n för ett kontrakt.

public:
 void ExportContract(System::ServiceModel::Description::WsdlExporter ^ exporter, System::ServiceModel::Description::WsdlContractConversionContext ^ context);
public void ExportContract(System.ServiceModel.Description.WsdlExporter exporter, System.ServiceModel.Description.WsdlContractConversionContext context);
abstract member ExportContract : System.ServiceModel.Description.WsdlExporter * System.ServiceModel.Description.WsdlContractConversionContext -> unit
Public Sub ExportContract (exporter As WsdlExporter, context As WsdlContractConversionContext)

Parametrar

exporter
WsdlExporter

Den WsdlExporter som exporterar kontraktsinformationen.

context
WsdlContractConversionContext

Innehåller mappningar från exporterade WSDL-element till kontraktsbeskrivningen.

Exempel

I följande kodexempel visas ett IWsdlExportExtension som lägger till anpassade dokumentationsattribut i WSDL-filen som WSDL-anteckningar.

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);
                }
            }
        }
    }
}

Kommentarer

Metoden ExportContract anropas när metadataexportsystemet exporterar kontraktet. Endast kontrakts- och åtgärdsbeteenden som implementerar IWsdlExportExtension anropet ExportContract . Alla beteenden som implementerar IWsdlExportExtension hämtar anropet ExportEndpoint .

Använd parametern context för att ändra WSDL som ska exporteras. Ett exempel finns i avsnittet Exempel.
