Remarks

If a given property is not contained in the current data source information instance (i.e., the method returns false), it delegates to the ADO.NET DataSourceInformation property's data table.

It is recommended that clients call this method before actually retrieving a value, as this may save retrieval of a value until it is actually needed.
