Specifies the type of objects to be looked for.
A type of the objects to be tested.
By default, this property is set to the attribute's target class.
When defining the RuleObjectExistsAttribute in code, the value for the LooksFor property is passed as a named parameter. This means that you do not have to specify it. However, when specifying, use the following format: LooksFor = typeof(Person) (LooksFor := TypeOf(Person), in Visual Basic).
