GetReportParameters 方法

傳回指定之報表的報表參數屬性。GetReportParameters(String, String, Boolean, array<ParameterValue>[]()[][], array<DataSourceCredentials>[]()[][]) 方法也可用來根據指定之報表的參數來驗證參數值。

命名空間：  ReportService2006
組件：  ReportService2006 (在 ReportService2006.dll 中)

參數

  • HistoryID
    型別：System. . :: . .String
    報表記錄快照集的識別碼。將 ForRendering 參數設定為 true 的值，以便為報表記錄快照集擷取參數屬性。如果為非報表記錄快照集的報表擷取參數，則將值設定為 nullNothingnullptrunitnull 參考 (在 Visual Basic 中為 Nothing) (Visual Basic 中則為 Nothing )。

傳回值

型別：array<ReportService2006. . :: . .ReportParameter> [] () [] []
ReportParameter 物件的陣列，會列出報表的參數清單。

ViewListItems()()()()

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 the credential information that is required to return the query parameters.

When using the GetReportParameters(String, String, Boolean, array<ParameterValue>[]()[][], array<DataSourceCredentials>[]()[][]) 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.
