public virtual Azure.Pageable<BinaryData> GetDevices (string filter = default, Azure.RequestContext context = default);

abstract member GetDevices : string * Azure.RequestContext -> Azure.Pageable<BinaryData>
override this.GetDevices : string * Azure.RequestContext -> Azure.Pageable<BinaryData>

Public Overridable Function GetDevices (Optional filter As String = Nothing, Optional context As RequestContext = Nothing) As Pageable(Of BinaryData)

Paramètres

filter: String

Restreint l’ensemble des appareils retournés. Vous pouvez filtrer sur GroupId, DeviceClassId ou GroupId et DeploymentStatus. Utilisez DeploymentStatus eq null pour interroger les appareils sans status de déploiement (qui n’ont jamais été déployés sur).

context: RequestContext

Contexte de la demande, qui peut remplacer les comportements par défaut du pipeline client par appel.

Retours

Pageable<BinaryData>

du Pageable<T> service contenant une liste d’objets BinaryData . Les détails du schéma de corps pour chaque élément de la collection sont décrits dans la section Remarques ci-dessous.

Exceptions

RequestFailedException

Le service a retourné un code de status non réussi.

Exemples

Cet exemple montre comment appeler GetDevices et analyser le résultat.

var credential = new DefaultAzureCredential();
var endpoint = new Uri("<https://my-service.azure.com>");
var client = new DeviceManagementClient(endpoint, "<instanceId>", credential);

foreach (var data in client.GetDevices())
{
    JsonElement result = JsonDocument.Parse(data.ToStream()).RootElement;
    Console.WriteLine(result.GetProperty("deviceId").ToString());
    Console.WriteLine(result.GetProperty("deviceClassId").ToString());
    Console.WriteLine(result.GetProperty("onLatestUpdate").ToString());
}
