Parâmetros

filter

String

Restringe o conjunto de dispositivos retornados. Você pode filtrar GroupId, DeviceClassId ou GroupId e DeploymentStatus. Use DeploymentStatus eq null para consultar dispositivos sem status de implantação (que nunca foram implantados).

context

RequestContext

O contexto de solicitação, que pode substituir os comportamentos padrão do pipeline do cliente por chamada.

Retornos

Pageable<BinaryData>

O Pageable<T> do serviço que contém uma lista de BinaryData objetos. Os detalhes do esquema do corpo de cada item na coleção estão na seção Comentários abaixo.

Exceções

RequestFailedException

O serviço retornou um código de status sem êxito.

Exemplos

Este exemplo mostra como chamar GetDevices e analisar o resultado.

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());
}
