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...  
    }  
}
