The below article will provide you a small snippet of code,that can be used to intgrate the gmail calendar in you asp.net application.Basically,You need to pass the parameters like Username,Password,StartDate,EndDate to retrieve the appointment list.
I have created a custom class"CalendarInfo" to hold the appointment list.
"CalendarInfo" class contains the below properties.
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.Serialization;
[Serializable()]
public class CalendarInfo
{
private string _location;
private DateTime _startTime;
private DateTime _endTime;
private string _subject;
private string _body;
public string Location
{
get { return _location; }
set { _location = value; }
}
public DateTime StartTime
{
get { return _startTime; }
set { _startTime = value; }
}
public DateTime EndTime
{
get { return _endTime; }
set { _endTime = value; }
}
public string Subject
{
get { return _subject; }
set { _subject = value; }
}
public string Body
{
get { return _body; }
set { _body = value; }
}
}
private void GoogleCalendar(string username, string password, DateTime startdate, DateTime enddate)
{
List<CalendarInfo> _calendarEvents = new List<CalendarInfo>();
//pass logged in user credentials
CalendarService service = new CalendarService("exampleCo-exampleApp-1");
service.setUserCredentials(username, password);
EventQuery query = new EventQuery();
query.Uri = new Uri("https://www.google.com/calendar/feeds/default/private/full");
query.SortOrder = CalendarSortOrder.ascending;
try
{
EventFeed events = service.Query(query);
int n = events.Entries.Count;
if (events.Entries.Count > 0)
{
int x = 0;
string mes = string.Empty;
while (x < n)
{
Google.GData.Calendar.EventEntry entry = (Google.GData.Calendar.EventEntry)events.Entries[x];
if (entry.Times[0].StartTime.Date >= startdate && entry.Times[0].EndTime.Date <= enddate)
{
CalendarInfo objinfo = new CalendarInfo();
objinfo.Subject = entry.Title.Text;
objinfo.Body = entry.Content.Content;
objinfo.StartTime = Convert.ToDateTime(entry.Times[0].StartTime);
objinfo.EndTime = Convert.ToDateTime(entry.Times[0].EndTime);
objinfo.Location = entry.Locations[0].ValueString;
_calendarEvents.Add(objinfo);
}
x = x + 1;
}
}
}
