Examples

This sample shows how to call GetGroups and parse the result.

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.GetGroups())
{
    JsonElement result = JsonDocument.Parse(data.ToStream()).RootElement;
    Console.WriteLine(result.GetProperty("groupId").ToString());
    Console.WriteLine(result.GetProperty("groupType").ToString());
    Console.WriteLine(result.GetProperty("createdDateTime").ToString());
}
