Metodo GetItemParameters
Restituisce le proprietà del parametro per un elemento specificato. Questo metodo può essere utilizzato anche per convalidare i valori dei parametri rispetto ai parametri di un elemento specificato.

Parametri
- ItemPath
Tipo: System. . :: . .String
URL completo dell'elemento, inclusi il nome file e, in modalità SharePoint, l'estensione.
- HistoryID
Tipo: System. . :: . .String
ID dello snapshot della cronologia dell'elemento. Impostare il parametro ForRendering sul valore true per recuperare le proprietà dei parametri per uno snapshot della cronologia dell'elemento. Impostare il valore su nullNothingnullptrunitriferimento Null (Nothing in Visual Basic). (Nothing in Visual Basic) se si recuperano parametri per un elemento che non rappresenta uno snapshot della cronologia dell'elemento.
- ForRendering
Tipo: System. . :: . .Boolean
Espressione booleana che indica come devono essere utilizzati i valori del parametro. Se impostata sul valore true, le proprietà restituite dei parametri si basano sui dati dei parametri utilizzati durante l'esecuzione dell'elemento.
- Values
Tipo: array<ReportService2010. . :: . .ParameterValue> [] () [] []
Valori dei parametri (oggetti ParameterValue) che possono essere convalidati rispetto ai parametri di un elemento gestito dal server di report.
- Credentials
Tipo: array<ReportService2010. . :: . .DataSourceCredentials> [] () [] []
Credenziali per l'origine dati (oggetti DataSourceCredentials) che possono essere utilizzate per convalidare i parametri delle query.
Valore restituito
Tipo: array<ReportService2010. . :: . .ItemParameter> [] () [] []
Matrice di oggetti ItemParameter in cui sono elencati i parametri per l'elemento.

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.
Esempi
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:
