为 GetProperties 方法设置项命名空间

可以根据两个不同的项标识符在 Reporting Services 中使用 ItemNamespaceHeader SOAP 标头：项的完整路径或项的 ID。

当您调用 GetProperties 方法时，通常将要检索其属性的项的完整路径作为参数传递。 使用 ItemNamespaceHeader，您可以为方法调用设置 SOAP 标头，以便通过将项的 ID 作为标识符传递来使用 GetProperties。

以下代码示例根据项的 ID 检索项属性的值。

注意
默认情况下，如果您将完整路径名称作为项标识符传递到 GetProperties 方法，则不需要为 ItemNamespaceHeader 设置值。

Imports System
Imports System.Collections


Class Sample
   Sub Main()
      Dim rs As New ReportingService2010()
      rs.Credentials = System.Net.CredentialCache.DefaultCredentials
      rs.Url = "http://<Server Name>/reportserver/ReportService2010.asmx"

      Dim items() As CatalogItem

      Try
         ' Need the ID property of items. Normally, you would already have 
         ' this stored somewhere.
         items = rs.ListChildren("/AdventureWorks Sample Reports", False)

         ' Set the item namespace header to be GUID-based
         rs.ItemNamespaceHeaderValue = New ItemNamespaceHeader()
         rs.ItemNamespaceHeaderValue.ItemNamespace = ItemNamespaceEnum.GUIDBased

         ' Call GetProperties with item ID.
         If Not (items Is Nothing) Then
            Dim item As CatalogItem
            For Each item In  items
               Dim properties As [Property]() = rs.GetProperties(item.ID, Nothing)
               Dim property As [Property]
               For Each property In  properties
                  Console.WriteLine(([property].Name + ": " + [property].Value))
               Next property
               Console.WriteLine()
            Next item
         End If

      Catch e As Exception
         Console.WriteLine((e.Message + ": " + e.StackTrace))
      End Try
   End Sub 'Main
End Class 'Sample

         rs.ItemNamespaceHeaderValue.ItemNamespace = ItemNamespaceEnum.GUIDBased;

         // Call GetProperties with item ID.
         if (items != null)
         {
            foreach( CatalogItem item in items)
            {
               Property[] properties = rs.GetProperties(item.ID, null);
               foreach (Property property in properties)
               {
                  Console.WriteLine(property.Name + ": " + property.Value);
               }
               Console.WriteLine();
            }
         }
