範例

要編譯以下程式碼範例，您必須參考 Reporting Services WSDL 並匯入特定命名空間。 欲了解更多資訊，請參閱編 譯與執行程式碼範例。 以下程式碼範例會取得使用者「我的報告」資料夾中的項目清單，然後透過批次操作刪除這些項目：

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;  
      }  
   }  
}  

備註

你可以在 SOAP 標頭中使用這個 BatchHeaderValue 屬性來處理你想要批次處理的 Web 服務呼叫。

執行批次時，請將報表伺服器網路服務的屬性設定 BatchHeaderValue 為與批次建立時產生的批次 ID 相等的值。 例如，以下 C# 程式碼將報表伺服器網路服務的值設 BatchHeaderValue 為等於先前建立的批次 ID，然後執行批次：

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

欲了解更多關於建立批次 ID 的資訊，請參閱 CreateBatch 方法。
