Beispiele

In diesem Beispiel wird gezeigt, wie Sie GetDeviceAsync mit den erforderlichen Parametern aufrufen und das Ergebnis analysieren.

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

Response response = await client.GetDeviceAsync("<deviceId>");

JsonElement result = JsonDocument.Parse(response.ContentStream).RootElement;
Console.WriteLine(result.GetProperty("deviceId").ToString());
Console.WriteLine(result.GetProperty("moduleId").ToString());
Console.WriteLine(result.GetProperty("deviceClassId").ToString());
Console.WriteLine(result.GetProperty("groupId").ToString());
Console.WriteLine(result.GetProperty("lastAttemptedUpdate").GetProperty("updateId").GetProperty("provider").ToString());
Console.WriteLine(result.GetProperty("lastAttemptedUpdate").GetProperty("updateId").GetProperty("name").ToString());
Console.WriteLine(result.GetProperty("lastAttemptedUpdate").GetProperty("updateId").GetProperty("version").ToString());
Console.WriteLine(result.GetProperty("lastAttemptedUpdate").GetProperty("description").ToString());
