Menentukan apakah objek yang ditentukan valid.

Overload

Nama	Deskripsi
TryValidateObject(Object, ValidationContext, ICollection<ValidationResult>)	Menentukan apakah objek yang ditentukan valid menggunakan konteks validasi dan pengumpulan hasil validasi.
TryValidateObject(Object, ValidationContext, ICollection<ValidationResult>, Boolean)	Menentukan apakah objek yang ditentukan valid menggunakan konteks validasi, pengumpulan hasil validasi, dan nilai yang menentukan apakah akan memvalidasi semua properti.

Public Shared Function TryValidateObject (instance As Object, validationContext As ValidationContext, validationResults As ICollection(Of ValidationResult)) As Boolean

Parameter

instance: Object

Objek yang akan divalidasi.

validationContext: ValidationContext

Konteks yang menjelaskan objek untuk divalidasi.

validationResults: ICollection<ValidationResult>

Koleksi untuk menyimpan setiap validasi yang gagal.

Mengembalikan

Boolean

true jika objek memvalidasi; jika tidak, false.

Atribut: RequiresUnreferencedCodeAttribute

Pengecualian

ArgumentNullException

instance adalah null.

ArgumentException

instancetidak cocok dengan pada ObjectInstancevalidationContext.

Keterangan

Metode ini mengevaluasi setiap ValidationAttribute instans yang dilampirkan ke jenis objek. Ini juga memeriksa apakah setiap properti yang ditandai dengan RequiredAttribute disediakan. Ini tidak memvalidasi nilai properti objek secara rekursif.

Public Shared Function TryValidateObject (instance As Object, validationContext As ValidationContext, validationResults As ICollection(Of ValidationResult), validateAllProperties As Boolean) As Boolean

Parameter

instance: Object

Objek yang akan divalidasi.

validationContext: ValidationContext

Konteks yang menjelaskan objek untuk divalidasi.

validationResults: ICollection<ValidationResult>

Koleksi untuk menyimpan setiap validasi yang gagal.

validateAllProperties: Boolean

true untuk memvalidasi semua properti; jika false, hanya atribut yang diperlukan yang divalidasi.

Mengembalikan

Boolean

true jika objek memvalidasi; jika tidak, false.

Atribut: RequiresUnreferencedCodeAttribute

Pengecualian

ArgumentNullException

instance adalah null.

ArgumentException

Keterangan

Metode ini mengevaluasi setiap ValidationAttribute instans yang dilampirkan ke jenis objek. Ini juga memeriksa apakah setiap properti yang ditandai dengan RequiredAttribute disediakan. Ini memvalidasi nilai properti objek jika validateAllProperties tetapi true tidak memvalidasi properti objek yang dikembalikan oleh properti secara rekursif.
