Замечания

You can use the BatchHeaderValue property in the SOAP header for Web service calls that you want to batch.

To execute a batch, set the BatchHeaderValue property of the Report Server Web service to a value that is equal to the batch ID generated when the batch was created. For example, the following C# code sets the BatchHeaderValue of the Report Server Web service to a value that is equal to a previously created batch ID and then executes the batch:

rs.BatchHeaderValue = bh;
rs.ExecuteBatch();

For more information about creating a batch ID, see CreateBatch method.

Пример

To compile the following code example, you must reference the Reporting Services WSDL and import certain namespaces. For more information, see Компиляция и запуск примеров кода. The following code example retrieves a list of items in a user's My Reports folder and then deletes the items using a batch operation:

Imports System
Imports System.Web.Services.Protocols

Class Sample
   Public Shared Sub Main()
      Dim rs As New ReportingService2005()
      rs.Credentials = System.Net.CredentialCache.DefaultCredentials

      ' Return all items in the My Reports folder.
      Dim items As CatalogItem() = rs.ListChildren("/My Reports", False)

      Dim bh As New BatchHeader()
      bh.BatchID = rs.CreateBatch()
      rs.BatchHeaderValue = bh

      Dim item As CatalogItem
      For Each item In  items
         Console.WriteLine((item.Path + " found."))
         rs.DeleteItem(item.Path)
         Console.WriteLine((item.Path + " deleted."))
      Next item

      Try
         rs.ExecuteBatch()
      Catch ex As SoapException
         Console.WriteLine(ex.Message)
      Finally
         rs.BatchHeaderValue = Nothing
      End Try
   End Sub 'Main
End Class 'Sample

using System;
using System.Web.Services.Protocols;

class Sample
{
   public static void Main()
   {
      ReportingService2005 rs = new ReportingService2005();
      rs.Credentials = System.Net.CredentialCache.DefaultCredentials;

      // Return all items in the My Reports folder.
      CatalogItem[] items = rs.ListChildren("/My Reports", false);

      BatchHeader bh = new BatchHeader();
      bh.BatchID = rs.CreateBatch();
      rs.BatchHeaderValue = bh;

      foreach (CatalogItem item in items)
      {
         Console.WriteLine(item.Path + " found.");
         rs.DeleteItem(item.Path);
         Console.WriteLine(item.Path + " deleted.");
      }

      try
      {
         rs.ExecuteBatch();
      }
      catch (SoapException ex)
      {
         Console.WriteLine(ex.Message);
      }
      finally
      {
         rs.BatchHeaderValue = null;
      }
   }
}
