Exemples

L’exemple de code suivant illustre l’utilisation de cette propriété.

public static void ShowRequestProperties1 (HttpListenerRequest request)

    string[] types = request.AcceptTypes;
    if (types != null)

Remarques

L’en-tête Accept est une chaîne de noms de types MIME (Multipurpose Internet Mail Extensions) séparés par l’espace (par exemple), image/jpegqui indiquent les types MIME que le client est prêt à accepter et à traiter dans une réponse. L’entrée */* indique que le client accepte n’importe quel type MIME. Pour obtenir une description détaillée de l’en-tête Accept , consultez RFC 2616, disponible à l’adresse https://www.rfc-editor.org.

Pour obtenir la liste complète des en-têtes de requête, consultez l’énumération HttpRequestHeader .
