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

Syntax

    validationContext As ValidationContext _
) As ValidationResult

public ValidationResult GetValidationResult(
    Object value,
    ValidationContext validationContext
)

Parameters

Type: System.ComponentModel.DataAnnotations.ValidationResult
Success if the value is valid; otherwise, an instance of the ValidationResult class with the error message.

Exceptions

Remarks

When you create a class that derives from the ValidationAttribute class, override the IsValid method to provide the customized validation logic. The GetValidationResult method calls the IsValid method to determine if the value is valid.
