Exemples

Cet exemple montre comment appeler GetUpdateAsync avec les paramètres requis et analyser le résultat.

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

Response response = await client.GetUpdateAsync("<provider>", "<name>", "<version>");

JsonElement result = JsonDocument.Parse(response.ContentStream).RootElement;
Console.WriteLine(result.GetProperty("updateId").GetProperty("provider").ToString());
