help me understand the method Validator.TryValidateObject()

Question

this is the method definition:

public static bool TryValidateObject(
Object instance,
ValidationContext validationContext,
ICollection<ValidationResult> validationResults,
bool validateAllProperties

)

what i am confused is the validateAllProperties parameter, I understand when it is true-validate all properties.

What about when it is false, not validate all properties, but which property will be validated?

See here for a good answer:

It seems that when validateAllProperties is set to false that only the RequiredAttribute is validated.
