Property Value

true if the field's DataType is numeric and the underlying field increments automatically as new rows are added; otherwise, false.

For a DataColumn object, the Identity property corresponds to the AutoIncrement property. In SQL Server, an Identity column is a numerical column that automatically increments with each added record, thereby ensuring that the value uniquely identifies that record.
