- instance
- Object
The object to validate.
- validationContext
- ValidationContext
The context that describes the object to validate.
- validationResults
- ICollection<ValidationResult>
A collection to hold each failed validation.
Returns
true if the object validates; otherwise, false.
Exceptions
instance is null.
instance doesn't match the ObjectInstanceon validationContext.
Remarks
This method evaluates each ValidationAttribute instance that is attached to the object type. It also checks whether each property that is marked with RequiredAttribute is provided. It does not recursively validate the property values of the object.

- instance
- Object
The object to validate.
- validationContext
- ValidationContext
The context that describes the object to validate.
- validationResults
- ICollection<ValidationResult>
A collection to hold each failed validation.
- validateAllProperties
- Boolean
true to validate all properties; if false, only required attributes are validated.
Returns
true if the object validates; otherwise, false.
Exceptions
instance is null.
instance doesn't match theObjectInstanceon validationContext.
Remarks
This method evaluates each ValidationAttribute instance that is attached to the object type. It also checks whether each property that is marked with RequiredAttribute is provided. It validates the property values of the object if validateAllProperties is true but does not recursively validate properties of the objects returned by the properties.
