Public Shared Sub ValidateObject (instance As Object, validationContext As ValidationContext)

参数

instance: Object

要验证的对象。

validationContext: ValidationContext

描述要验证的对象的上下文。

属性: RequiresUnreferencedCodeAttribute

例外

ValidationException

对象无效。

ArgumentNullException

instance 是 null。

ArgumentException

instance与 on ObjectInstance不匹配validationContext。

注解

此方法评估附加到对象类型的每个 ValidationAttribute 实例。
