示例

此示例演示如何使用所需参数调用 GetGroup 并分析结果。

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

Response response = client.GetGroup("<groupId>");

JsonElement result = JsonDocument.Parse(response.ContentStream).RootElement;
Console.WriteLine(result.GetProperty("groupId").ToString());
Console.WriteLine(result.GetProperty("groupType").ToString());
Console.WriteLine(result.GetProperty("createdDateTime").ToString());
Console.WriteLine(result.GetProperty("deviceCount").ToString());
Console.WriteLine(result.GetProperty("subgroupsWithNewUpdatesAvailableCount").ToString());
Console.WriteLine(result.GetProperty("subgroupsWithUpdatesInProgressCount").ToString());
Console.WriteLine(result.GetProperty("subgroupsWithOnLatestUpdateCount").ToString());
Console.WriteLine(result.GetProperty("deployments")[0].ToString());
