Google Calendar API，只需知道他们的电子邮件地址即可向某人的日历添加活动

我已经下载了Google.Apis名称空间：

using Google.Apis.Auth.OAuth2; using Google.Apis.Calendar.v3; using Google.Apis.Calendar.v3.Data; using Google.Apis.Services; 

我花了一整天的时间在网上查看.NET示例，了解如何通过了解他们的电子邮件地址将事件添加到某人日历中。

我尝试了下面的代码，但它带来了错误，很明显它不会起作用：

 Public void Method(string email, string text) { UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync( new ClientSecrets { ClientId = "CLIENTID", ClientSecret = "CLIENTSECRET", }, new[] { CalendarService.Scope.Calendar }, "user", CancellationToken.None).Result; // Create the service. var service = new CalendarService(new BaseClientService.Initializer() { HttpClientInitializer = credential, ApplicationName = "Calendar API Sample", }); Event event1 = new Event() { Summary = "Something", Location = "Somewhere", Start = new EventDateTime() { DateTime = DateTime.Now, TimeZone = "America/Los_Angeles" }, End = new EventDateTime() { DateTime = DateTime.Now, TimeZone = "America/Los_Angeles" }, Attendees = new List() { new EventAttendee() { Email: email } //bringing up an error "Syntax ',' expected } }; Event thisevent = service.Events.Insert(event1, "primary").Fetch(); // Another error. "Does not contain a definition for Fetch" } 

任何帮助表示赞赏！ 甚至其他代码的样本:)

Answer 1

在您创建事件并插入事件的部分中存在语法错误。 以下是一个具有Google API .NET库正确语法的代码段：

 Event myEvent = new Event { Summary = "Appointment", Location = "Somewhere", Start = new EventDateTime() { DateTime = new DateTime(2014, 6, 2, 10, 0, 0), TimeZone = "America/Los_Angeles" }, End = new EventDateTime() { DateTime = new DateTime(2014, 6, 2, 10, 30, 0), TimeZone = "America/Los_Angeles" }, Recurrence = new String[] { "RRULE:FREQ=WEEKLY;BYDAY=MO" }, Attendees = new List() { new EventAttendee() { Email = "[e-mail]" } } }; Event recurringEvent = service.Events.Insert(myEvent, "primary").Execute();
