IWsdlExportExtension.ExportEndpoint 方法

定義

命名空間:

System.ServiceModel.Description

組件:

System.ServiceModel.dll

將自訂的 Web 服務描述語言 (WSDL) 項目寫入為端點產生的 WSDL。

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)

參數

exporter

WsdlExporter

WsdlExporter，可匯出端點資訊。

context

WsdlEndpointConversionContext

提供從匯出的 WSDL 項目到端點描述之間的對應。

範例

下列程式碼範例將示範 IWsdlExportExtension，它會將自訂文件屬性當做 WSDL 附註加入至 WSDL 檔案中。

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);
                }
            }
        }
    }
}

備註

實作 ExportEndpoint 方法以修改為端點匯出的 WSDL。 這個方法會在 ExportContract 匯出合約後呼叫。
