VB RS.exe - 未定义数据源

Question

我有这段代码可以以编程方式将报告导出为 PDF。

Public Sub Main()

TRY

 DIM historyID as string = Nothing
 DIM deviceInfo as string = Nothing
 DIM extension as string = Nothing
 DIM encoding as string
 DIM mimeType as string = "application/Excel"
 DIM warnings() AS Warning = Nothing
 DIM streamIDs() as string = Nothing
 DIM results() as Byte


 rs.Credentials = System.Net.CredentialCache.DefaultCredentials
 Dim dataSources() As DataSource = rs.GetItemDataSources("foldername/reportname")

 rs.LoadReport(REPORTSERVER_FOLDER, historyID)

 results = rs.Render(FORMAT, deviceInfo, extension, mimeType, encoding, warnings, streamIDs)

 DIM stream As FileStream = File.OpenWrite(FILENAME)
 stream.Write(results, 0, results.Length)
 stream.Close()

Catch e As IOException
  Console.WriteLine(e.Message)
End Try

End Sub

当我运行时，我收到一条错误消息：

error BC30002: Type 'DataSource' is not defined.

 Dim dataSources() As DataSource = rs.GetItemDataSources("foldername/reportname")
                      ~~~~~~~~~~

我是不是忘记导入什么东西了？如果我删除该行它工作正常（除此之外它需要添加一个数据源）。预先添加数据源不是一个选项。

Answer 1

所以我想出了答案。我正在使用 Exec2005（执行端点），它不包括 DataSource 的定义。我应该改为使用默认端点 (Mgmt2005)，但这会导致代码中出现其他问题。

无论如何，这个问题的答案是不使用-e Exec2005。
