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

參數

instance: Object

要驗證的對象。

validationContext: ValidationContext

描述物件的上下文需要驗證。

屬性: RequiresUnreferencedCodeAttribute

例外狀況

ValidationException

這個物件本身並不有效。

ArgumentNullException

instance 是 null。

ArgumentException

instance與 on ObjectInstance不符validationContext。

備註

此方法評估每個 ValidationAttribute 附加於物件型別的實例。
