Parameters
- value
- Type: System.Object
The value to validate.
- validationContext
- Type: System.ComponentModel.DataAnnotations.ValidationContext
The context that describes the object to validate.

A collection to hold failed validations.
- validationAttributes
- Type: System.Collections.Generic.IEnumerable<ValidationAttribute>
The validation attributes.
This method tests each validation attribute in the validationAttributes parameter against the value parameter. If the validationResults parameter is not null, this method adds a ValidationResult object for each validation failure to the validation results collection. If the validationResults parameter is null, this method does not add a ValidationResult object to the collection. If a RequiredAttribute attribute is included in the validationAttributes parameter, the RequiredAttribute attribute is evaluated first.
