Microsoft Graph：无法更新事件的开始或结束日期

Question

我正在使用 Microsoft Graph .NET SDK to update outlook events. Following code successfully updates the Subject, and Body attributes of an event. But when I try to update the Start and/or End dates of the the event (that are of the dateTimeTimeZone 类型）我收到如下所示的错误：

问题: 错误的原因可能是什么，我们该如何解决？请注意，该活动的有效本地开始日期和结束日期分别为 8/21/2020 11:00AM 和 8/21/2020 11:30AM。实际上，在调试模式下，VS2019 显示：Start.get returns null

错误截图:

代码:

如果我取消注释下面的 Start = { DateTime = "2020-08-20T08:30:00.0000000", TimeZone = "UTC" } 行，就会出现上述错误。
authProvider 和 "{id}" 变量的值与错误无关，因为具有实际值的代码在没有代码行 Start =.... 的情况下工作正常。

...

GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var @event = new Event
{
    Subject = "Test subject",
    Body= new ItemBody { Content = "Test body content"}
    //Start = { DateTime = "2020-08-20T08:30:00.0000000", TimeZone = "UTC" }
};

await graphClient.Me.Events["{id}"]
    .Request()
    .UpdateAsync(@event);

Answer 1

你需要这样的东西，因为属性

中使用了对象类型

            var @event = new Event
        {
            Subject = "Test subject",
            Body = new ItemBody { Content = "Test body content" },
            Start = new DateTimeTimeZone {  DateTime = "2020-08-20T08:30:00.0000000", TimeZone = "UTC" } 
        };

Answer 2

您需要按照以下格式添加日期。希望它能解决您的问题。

var @event = new Event
    {
        Subject = "Test subject",
        Body = new ItemBody { Content = "Test body content" },
        Start = new DateTimeTimeZone {  DateTime = "2020-08-20T08:30:00.0000000", TimeZone = "GMT Standard Time" } 
    };
