[英]How to create an event in Google Calendar using c# and Google API?
UPDATE: I solved this problem and posted the solution as an answer below!更新:我解决了这个问题并在下面发布了解决方案作为答案! ;) ;)
I need to create an event and add it to Google Calendar using Google API.我需要创建一个事件并使用 Google API 将其添加到 Google 日历。
For now I only know how to get all the events I have from Google Calendar.目前我只知道如何从 Google 日历中获取我拥有的所有活动。 This is what I've got so far:这是我到目前为止所得到的:
using Google.Apis.Auth.OAuth2;
using Google.Apis.Calendar.v3;
using Google.Apis.Calendar.v3.Data;
using Google.Apis.Services;
using Google.Apis.Util.Store;
namespace CalendarQuickstart
{
class Program
{
// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/calendar-dotnet-quickstart.json
static string[] Scopes = { CalendarService.Scope.CalendarReadonly };
static string ApplicationName = "Google Calendar API .NET Quickstart";
static void Main(string[] args)
{
UserCredential credential;
using (var stream =
new FileStream("credentials.json", FileMode.Open, FileAccess.Read))
{
// The file token.json stores the user's access and refresh tokens, and is created
// automatically when the authorization flow completes for the first time.
string credPath = "token.json";
credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
GoogleClientSecrets.Load(stream).Secrets,
Scopes,
"user",
CancellationToken.None,
new FileDataStore(credPath, true)).Result;
Console.WriteLine("Credential file saved to: " + credPath);
}
// Create Google Calendar API service.
var service = new CalendarService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = ApplicationName,
});
// Define parameters of request.
EventsResource.ListRequest request = service.Events.List("primary");
request.TimeMin = DateTime.Now;
request.ShowDeleted = false;
request.SingleEvents = true;
request.MaxResults = 10;
request.OrderBy = EventsResource.ListRequest.OrderByEnum.StartTime;
// List events.
Events events = request.Execute();
Console.WriteLine("Upcoming events:");
if (events.Items != null && events.Items.Count > 0)
{
foreach (var eventItem in events.Items)
{
string when = eventItem.Start.DateTime.ToString();
if (String.IsNullOrEmpty(when))
{
when = eventItem.Start.Date;
}
Console.WriteLine("{0} ({1})", eventItem.Summary, when);
}
}
else
{
Console.WriteLine("No upcoming events found.");
}
Console.Read();
}
}
}
What I am trying to do must be looking something like this:我正在尝试做的必须看起来像这样:
var ev = new Event();
EventDateTime start = new EventDateTime();
start.DateTime = new DateTime(2019, 3, 11, 10, 0, 0);
EventDateTime end = new EventDateTime();
end.DateTime = new DateTime(2019, 3, 11, 10, 30, 0);
ev.Start = start;
ev.End = end;
ev.Description = "Description...";
events.Items.Insert(0, ev);
I've spent the entire day searching any .NET samples but got nothing.我花了一整天的时间搜索任何 .NET 示例,但一无所获。 Any help appreciated!任何帮助表示赞赏! ;) ;)
I've solved this problem!我已经解决了这个问题! So before building the project change所以在构建项目之前改变
static string[] Scopes = { CalendarService.Scope.CalendarReadonly };
to到
static string[] Scopes = { CalendarService.Scope.Calendar };
If you already built the solution then delete credentials.json file and then reload it.如果您已经构建了解决方案,则删除凭据.json文件,然后重新加载它。 The code for adding an event is here:添加事件的代码在这里:
var ev = new Event();
EventDateTime start = new EventDateTime();
start.DateTime = new DateTime(2019, 3, 11, 10, 0, 0);
EventDateTime end = new EventDateTime();
end.DateTime = new DateTime(2019, 3, 11, 10, 30, 0);
ev.Start = start;
ev.End = end;
ev.Summary = "New Event";
ev.Description = "Description...";
var calendarId = "primary";
Event recurringEvent = service.Events.Insert(ev, calendarId).Execute();
Console.WriteLine("Event created: %s\n", e.HtmlLink);
This is my first try with Google API so don't judge me ;) Hope it helps somebody one day!这是我第一次尝试使用 Google API,所以不要评判我 ;) 希望有一天能对某人有所帮助!
Note : You also need to remove the 'token.json' folder from \\bin\\debug folder注意:您还需要从 \\bin\\debug 文件夹中删除“token.json”文件夹
I try to do the same thing in this days I used your same code, but just in the first part (reading events) the system arise me an exception "System.InvalidOperationException: 'At least one client secrets (Installed or Web) should be set'" calling the method credential = GoogleWebAuthorizationBroker.AuthorizeAsync这几天我尝试做同样的事情,我使用了相同的代码,但就在第一部分(读取事件)中,系统出现了一个异常“System.InvalidOperationException:'至少一个客户端机密(已安装或 Web)应该是set'" 调用方法 credential = GoogleWebAuthorizationBroker.AuthorizeAsync
Have somebody a solution for this issue?有人解决了这个问题吗?
