例

このサンプルでは、GetUpdatesAsync を呼び出して結果を解析する方法を示します。

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

await foreach (var data in client.GetUpdatesAsync())
{
    JsonElement result = JsonDocument.Parse(data.ToStream()).RootElement;
    Console.WriteLine(result.GetProperty("updateId").GetProperty("provider").ToString());
    Console.WriteLine(result.GetProperty("updateId").GetProperty("name").ToString());
    Console.WriteLine(result.GetProperty("updateId").GetProperty("version").ToString());
    Console.WriteLine(result.GetProperty("compatibility")[0].GetProperty("<test>").ToString());
    Console.WriteLine(result.GetProperty("manifestVersion").ToString());
    Console.WriteLine(result.GetProperty("importedDateTime").ToString());
    Console.WriteLine(result.GetProperty("createdDateTime").ToString());
}
