Remarks
An InvalidDataSourceReference object is used with the Item property as output by GetItemDataSources 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 Item property of the DataSource class, 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...
}
}
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
