Parâmetros
- Report
Tipo: System.String
The full path name of the report.
- HistoryID
Tipo: System.String
The ID of the report history snapshot. Set the ForRendering parameter to a value of true in order to retrieve parameter properties for a report history snapshot. Set the value to nulluma referência nula (Nothing no Visual Basic) (Nothing in Visual Basic) if you are retrieving parameters for a report that is not a report history snapshot.
- ForRendering
Tipo: System.Boolean
A Boolean expression that indicates how the parameter values are to be used. If set to a value of true, parameter properties that are returned are based on the parameter data that was used during the execution of the report.
- Values
Tipo: array<ReportService2005.ParameterValue[]
The parameter values (ParameterValue objects) that can be validated against the parameters of a report that is managed by the report server.
- Credentials
Tipo: array<ReportService2005.DataSourceCredentials[]
The data source credentials (DataSourceCredentials objects) that can be used to validate query parameters.
Valor de retorno
Tipo: array<ReportService2005.ReportParameter[]
An array of ReportParameter objects that lists the parameters for the report.

If the execution setting for the report is Snapshot, the parameter metadata that is returned is the data that was used when the report history snapshot was created. If the execution setting for the report is Live, the parameter metadata returned represents the parameter data that is associated with the specified report.
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 report 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 report.
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 GetReportParameters method to validate parameters, the Values parameter is required.
If report parameters do not exist for the given report, an empty ReportParameter array is returned.
Exemplos
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 GetReportParameters method to retrieve a list of parameter metadata for a report and then displays the name of each parameter:
