Microsoft Silverlight will reach end of support after October 2021. Learn more.

Determines whether the specified object is valid and, if requested, whether all of the properties on the object are valid, and throws a ValidationException if the object is not valid.

Namespace:  System.ComponentModel.DataAnnotations
Assembly:  System.ComponentModel.DataAnnotations (in System.ComponentModel.DataAnnotations.dll)

Syntax

'Declaration
Public Shared Sub ValidateObject ( _
    instance As Object, _
    validationContext As ValidationContext, _
    validateAllProperties As Boolean _
)

public static void ValidateObject(
    Object instance,
    ValidationContext validationContext,
    bool validateAllProperties
)

Parameters

  • validateAllProperties
    Type: System.Boolean
    A value that indicates whether all immediate properties of the object are validated.

Exceptions

Exception Condition
ArgumentNullException

instance is null.

-or-

validationContext is null.
ArgumentException

instance does not equal the ObjectInstance on validationContext.
ValidationException

instance or at least one of its properties is not valid.

Remarks

The ValidateObject method evaluates each ValidationAttribute attribute that is associated with the object type. If validateAllProperties is set to true, the method validates the property values of the object. Class-level validation attributes are evaluated only if the property-level attributes are valid.
