WsdlExporter.GetGeneratedMetadata 方法

定义

命名空间:

System.ServiceModel.Description

程序集:

System.ServiceModel.dll

返回所生成的 MetadataSection 对象的可枚举集合。

public:
 override System::ServiceModel::Description::MetadataSet ^ GetGeneratedMetadata();

public override System.ServiceModel.Description.MetadataSet GetGeneratedMetadata ();

override this.GetGeneratedMetadata : unit -> System.ServiceModel.Description.MetadataSet

Public Overrides Function GetGeneratedMetadata () As MetadataSet

返回

MetadataSet

所生成的 MetadataSection 对象的可枚举集合，表示生成为调用 ExportContract(ContractDescription)、ExportEndpoint(ServiceEndpoint) 或 ExportEndpoints(IEnumerable<ServiceEndpoint>, XmlQualifiedName) 的结果的元数据。

示例

下面的代码示例演示了如何使用 ExportEndpoint 方法，从 MetadataSection 所调用的 ServiceEndpoint 对象集合中的终结点生成一组 myServiceEndpoints 对象。

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();
            }
        }
    }
}

Imports System.ServiceModel
Imports System.ServiceModel.Description

Module Module1

    Sub Main()
        Dim exporter As New WsdlExporter()
        exporter.PolicyVersion = PolicyVersion.Policy15

        Dim myServiceEndpoints() As ServiceEndpoint = New ServiceEndpoint(1) {}
        Dim myDescription As 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.
        For Each endpoint As ServiceEndpoint In myServiceEndpoints
            exporter.ExportEndpoint(endpoint)
        Next

        'If there are no errors, get the documents.
        Dim metadataDocs As MetadataSet
        metadataDocs = Nothing

        If (exporter.Errors.Count = 0) Then
            metadataDocs = exporter.GetGeneratedMetadata()
        End If
    End Sub

End Module

注解

对于为所有 GetGeneratedMetadata、ExportContract 或 ExportEndpoint 调用所生成的结果，使用 ExportEndpoints 属性可获取这些结果的全部元数据的集合。

建议您在检索元数据前，先检查基本 Errors 属性，以确定是否有错误发生。
