ReportingService2005.CreateBatch 方法

定义

命名空间:

ReportService2005

程序集:

ReportService2005.dll

创建在单个事务内执行多个方法的批处理。

public:
 System::String ^ CreateBatch();

public string CreateBatch ();

member this.CreateBatch : unit -> string

Public Function CreateBatch () As String

返回

String

一个唯一标识批处理操作的String。

示例

若要编译此代码示例，必须引用 Reporting Services WSDL 并导入某些命名空间。 有关详细信息，请参阅 编译和运行代码示例。 下面的代码示例为两批 Web 服务方法调用创建批处理 ID，并执行批处理：

Imports System  
Imports System.Web.Services.Protocols  

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

      Dim bh1 As New BatchHeader()  
      Dim bh2 As New BatchHeader()  

      bh1.BatchID = rs.CreateBatch()  
      rs.BatchHeaderValue = bh1  
      rs.CreateFolder("New Folder1", "/", Nothing)  
      rs.CreateFolder("New Folder2", "/", Nothing)  
      rs.CreateFolder("New Folder3", "/", Nothing)  

      bh2.BatchID = rs.CreateBatch()  
      rs.BatchHeaderValue = bh2  
      rs.DeleteItem("/New Folder1")  
      rs.DeleteItem("/New Folder2")  
      rs.DeleteItem("/New Folder3")  

      rs.BatchHeaderValue = bh1  

      ' Create folders using a batch header 1.  
      Try  
         rs.ExecuteBatch()  
         Console.WriteLine("Folders created successfully.")  

      Catch e As SoapException  
         Console.WriteLine(e.Detail.InnerXml.ToString())  
      End Try  

      rs.BatchHeaderValue = bh2  

      ' Delete folders using batch header 2.  
      Try  
         rs.ExecuteBatch()  
         Console.WriteLine("Folders deleted successfully.")  

      Catch e As SoapException  
         Console.WriteLine(e.Detail.InnerXml.ToString())  

      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;  

      BatchHeader bh1 = new BatchHeader();  
      BatchHeader bh2 = new BatchHeader();  

      bh1.BatchID = rs.CreateBatch();  
      rs.BatchHeaderValue = bh1;  
      rs.CreateFolder("New Folder1", "/", null);  
      rs.CreateFolder("New Folder2", "/", null);  
      rs.CreateFolder("New Folder3", "/", null);  

      bh2.BatchID = rs.CreateBatch();  
      rs.BatchHeaderValue = bh2;  
      rs.DeleteItem("/New Folder1");  
      rs.DeleteItem("/New Folder2");  
      rs.DeleteItem("/New Folder3");  

      rs.BatchHeaderValue = bh1;  

      // Create folders using a batch header 1.  
      try  
      {  
         rs.ExecuteBatch();  
         Console.WriteLine("Folders created successfully.");  
      }  

      catch (SoapException e)  
      {  
         Console.WriteLine(e.Detail.InnerXml.ToString());  
      }  

      rs.BatchHeaderValue = bh2;  

      // Delete folders using batch header 2.  
      try  
      {  
         rs.ExecuteBatch();  
         Console.WriteLine("Folders deleted successfully.");  
      }  

      catch (SoapException e)  
      {  
         Console.WriteLine(e.Detail.InnerXml.ToString());  
      }  

      finally  
      {  
         rs.BatchHeaderValue = null;  
      }  
   }  
}  

注解

下表显示了有关此操作的标头和权限信息。

SOAP 标头	(Out) ServerInfoHeaderValue
所需的权限	用户必须是数据库管理员或配置为无人参与执行帐户的用户。 有关详细信息，请参阅 执行帐户 (SSRS 本机模式) 。

方法返回的 CreateBatch ID 用于对后续 Web 服务方法调用进行分组或批处理。 批处理中包含的每个方法都必须在 SOAP 标头中指定批 ID。 若要使用 Microsoft .NET Framework批处理方法调用，必须先将报表服务器 Web 服务代理类的 属性设置为BatchHeaderValue等于BatchHeader包含以前创建的批 ID 的对象的值。
