Property Value

Type: System::Boolean

true if the property is in the primary key of the data store; otherwise, false.

Set the PrimaryKey property to true when the DataObjectFieldAttribute attribute is applied to a property that represents the primary key value of the underlying data. The primary key is typically used by the underlying data store to uniquely identify an entity in the data store, and often is, but is not required to be, a data store identity field.

Set the PrimaryKey property with one of the DataObjectFieldAttribute constructors.
