Parameter
- ItemPath
Typ: System. . :: . .String
Die vollqualifizierte URL des Elements einschließlich des Dateinamens und (im SharePoint-Modus) der Erweiterung.
- HistoryID
Typ: System. . :: . .String
Die ID der Elementverlaufs-Momentaufnahme. Legen Sie den ForRendering-Parameter auf den Wert true fest, um Parametereigenschaften für eine Elementverlaufs-Momentaufnahme abzurufen. Legen Sie den Wert auf nullNothingnullptrunitein NULL-Verweis (Nothing in Visual Basic) (Nothing in Visual Basic) fest, wenn Sie Parameter für ein Element abrufen, bei dem es sich nicht um eine Elementverlaufs-Momentaufnahme handelt.
- ForRendering
Typ: System. . :: . .Boolean
Ein Boolean-Ausdruck, der angibt, wie die Parameterwerte verwendet werden sollen. Wenn true festgelegt wurde, basieren die zurückgegebenen Parametereigenschaften auf den Parameterdaten, die während der Ausführung des Elements verwendet wurden.
- Values
Typ: array<ReportService2010. . :: . .ParameterValue> [] () [] []
Die Parameterwerte (ParameterValue-Objekte), die für die Parameter eines Elements, das vom Berichtsserver verwaltet wird, validiert werden können.
- Credentials
Typ: array<ReportService2010. . :: . .DataSourceCredentials> [] () [] []
Die Anmeldeinformationen für die Datenquelle (DataSourceCredentials-Objekte), mit denen Abfrageparameter validiert werden können.
Rückgabewert
Typ: array<ReportService2010. . :: . .ItemParameter> [] () [] []
Ein Array von ItemParameter-Objekten, das die Parameter für das Element aufführt.

If the execution setting for the item is Snapshot, the parameter metadata that is returned is the data that was used when the item history snapshot was created. If the execution setting for the item is Live, the parameter metadata returned represents the parameter data that is associated with the specified item.
If you provide a value for the HistoryID parameter and set the ForRendering parameter value to true, the parameter metadata returned represents the parameter data that was used when the item history snapshot was created. The value supplied for HistoryID is ignored if ForRendering is set to false.If ForRendering is false, the parameter metadata returned represents the parameter data that is currently associated with the specified item.
If any parameters values are based on a query and you are interested in returning the query-based parameters' valid values list, set ForRendering to true. In addition, for query-based parameters, you must pass in all of the credential information required to return the query parameters.
When using the GetItemParameters method to validate parameters, the Values parameter is required.
If parameters do not exist for the given item, an empty ItemParameter array is returned.
Beispiele
To compile this code example, you must reference the Reporting Services WSDL and import certain namespaces. For more information, see Compiling and Running Code Examples. The following code example uses the GetItemParameters method to retrieve a list of parameter metadata for a report and then displays the name of each parameter:
