Remarks
An InvalidDataSourceReference object is used with the DataSource.Item property as output by the ReportingService.GetReportDataSources method.
In most cases, an InvalidDataSourceReference object is returned when a shared data source has been deleted.
To evaluate whether a data source reference is valid, use the is keyword in C# (TypeOf/Is in Visual Basic) to determine the type of object returned by the DataSource.Item property, as shown in the following C# code:
DataSource[] dataSource;
dataSource = service.GetReportDataSources( "/MyReport" );
foreach ( DataSource ds in dataSource )
{
if ( ds.Item is InvalidDataSourceReference )
{
// Code to handle a corrupt or missing data source reference goes here...
}
}
