[英]How to create a Google calendar event with C# and Google calendar API?
[英]How to create an event in Google Calendar using c# and Google API?
更新:我解決了這個問題並在下面發布了解決方案作為答案! ;)
我需要創建一個事件並使用 Google API 將其添加到 Google 日歷。
目前我只知道如何從 Google 日歷中獲取我擁有的所有活動。 這是我到目前為止所得到的:
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();
}
}
}
我正在嘗試做的必須看起來像這樣:
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);
我花了一整天的時間搜索任何 .NET 示例,但一無所獲。 任何幫助表示贊賞! ;)
我已經解決了這個問題! 所以在構建項目之前改變
static string[] Scopes = { CalendarService.Scope.CalendarReadonly };
到
static string[] Scopes = { CalendarService.Scope.Calendar };
如果您已經構建了解決方案,則刪除憑據.json文件,然后重新加載它。 添加事件的代碼在這里:
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);
這是我第一次嘗試使用 Google API,所以不要評判我 ;) 希望有一天能對某人有所幫助!
注意:您還需要從 \\bin\\debug 文件夾中刪除“token.json”文件夾
這幾天我嘗試做同樣的事情,我使用了相同的代碼,但就在第一部分(讀取事件)中,系統出現了一個異常“System.InvalidOperationException:'至少一個客戶端機密(已安裝或 Web)應該是set'" 調用方法 credential = GoogleWebAuthorizationBroker.AuthorizeAsync
有人解決了這個問題嗎?
