範例

要編譯此程式碼範例，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。 以下程式碼範例使用此 GetItemParameters 方法，取得報告的參數元資料清單，並顯示每個參數的名稱：

Imports System  
Imports System.Web.Services.Protocols  

Class Sample  
   Public Shared Sub Main()  
      Dim rs As New ReportingService2010()  
      rs.Credentials = System.Net.CredentialCache.DefaultCredentials  

      Dim report As String = "/SampleReports/Employee Sales Summary"  
      Dim forRendering As Boolean = False  
      Dim historyID As String = Nothing  
      Dim values As ParameterValue() = Nothing  
      Dim credentials As DataSourceCredentials() = Nothing  
      Dim parameters As ItemParameter() = Nothing  

      Try  
         parameters = rs.GetItemParameters(report, historyID, forRendering, values, credentials)  

         If Not (parameters Is Nothing) Then  
            Dim rp As ItemParameter  
            For Each rp In parameters  
               Console.WriteLine("Name: {0}", rp.Name)

備註

下表顯示此操作的標頭與權限資訊。

如果項目的執行設定為 Snapshot，回傳的參數元資料就是建立項目歷史快照時所使用的資料。 若項目的執行設定為 Live，回傳的參數元資料代表與指定項目相關的參數資料。

如果你為該參數提供一個值 HistoryID ，並將參數值設 ForRendering 為 ，true回傳的參數元資料代表在建立物品歷史快照時所使用的參數資料。 若 ForRendering 設定為 false，則忽略 的值HistoryID。若ForRendering為 ，false則回傳的參數元資料代表目前與指定項目相關聯的參數資料。

如果任何參數值是基於查詢，且你想回傳查詢參數的有效值清單，請設 ForRendering 為 true。 此外，基於查詢的參數，你必須傳遞所有憑證資訊以回傳查詢參數。

使用 GetItemParameters 該方法驗證參數時，必須有參數 Values 。

若該項目不存在參數，則回傳一個空 ItemParameter 陣列。
