透過 ReportObjects 集合的Item 屬性依索引或名稱來擷取 ReportObject 物件，並轉換 ReportObject 為 PictureObject。

範例

下列範例會傳回 PictureObject 物件。

[Visual Basic]

Private Function GetPictureObject _ 
(ByVal reportObjectName As String) As PictureObject
   Dim picture As PictureObject

   ' 依名稱取得 ReportObject，將之轉換為 PictureObject，
   '  然後將它傳回來。
   If TypeOf _
   (Report.ReportDefinition.ReportObjects. _ 
   Item(reportObjectName)) Is PictureObject Then
      picture = _ 
      Report.ReportDefinition.ReportObjects. _ 
      Item(reportObjectName)
      GetPictureObject = picture
   Else : GetPictureObject = Nothing
   End If
End Function

[C#]

private PictureObject GetPictureObject
(string reportObjectName)
{
   PictureObject picture;

   // 依名稱取得 ReportObject，將之轉換為 PictureObject，
   //  然後將它傳回來。
   picture = 
   Report.ReportDefinition.ReportObjects[reportObjectName] 
   as PictureObject;
   if (picture!= null) return picture;
   else return null;
}

[C++]

PictureObject* GetPictureObject(String* reportObjectName)
{
   PictureObject* picture;

   // 依名稱取得 ReportObject，將之轉換為 PictureObject，
   //  然後將它傳回來。
   try
   {
      picture = __try_cast<PictureObject*>
      (Report->ReportDefinition->
      ReportObjects->Item[reportObjectName]);
      return picture;
   }
   catch(System::InvalidCastException*)
   {
      return 0;
   }
};

[VJ#]

private PictureObject GetPictureObject
(String reportObjectName)
{
   PictureObject picture;

   // 依名稱取得 ReportObject，將之轉換為 PictureObject，
   //  然後將它傳回來。
   picture = (PictureObject)
Report.get_ReportDefinition().get_ReportObjects().get_Item(reportObjectName);
   if (picture!= null) return picture;
   else return null;
}
