ConstructorInfo

Objekt, který představuje konstruktor, který by inicializoval vlastní atribut reprezentovaný aktuální instancí CustomAttributeData třídy.

Atributy: ComVisibleAttribute

Příklady

Následující příklad definuje vlastní atribut se čtyřmi konstruktory a čtyřmi vlastnostmi. Dvě z vlastností jsou jen pro čtení a jsou nastaveny pomocí pozičních parametrů konstruktorů. Další dvě vlastnosti jsou čtení/zápis a lze je nastavit pouze pomocí pojmenovaných argumentů. Jedna poziční vlastnost je pole řetězců a jedna pojmenovaná vlastnost je pole celých čísel.

Atribut se použije na sestavení, na typ deklarovaný v sestavení, na metodu typu a na parametr metody metody. V těchto případech se používají různé konstruktory. Při spuštění se sestavení načte do kontextu jen pro reflexi a zobrazí vlastní atributy.

Atribut, který se použije na typ, ukazuje vlastnosti pole s pozičními i pojmenovanými argumenty.

Vlastnost Constructor se používá v ShowAttributeData metodě, která zobrazuje data vlastních atributů. V tomto příkladu ConstructorInfo kódu se vlastnost vrácená touto vlastností používá k zobrazení textového řetězce, který popisuje konstruktor, což demonstruje, že vlastnost vrací konstruktor, který by inicializoval atribut.
