Get occurrences

The following example shows you how to get all occurrences of a recurring calendar event within a date range.

C# example

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using Independentsoft.Graph;
using Independentsoft.Graph.Calendars;

namespace Sample
{
    class Program
    {
        static async Task Main(string[] args)
        {
            try
            {
                GraphClient client = new GraphClient();

                client.ClientId = "63333333-209e-454e-b7bd-55a4d201270f";
                client.Tenant = "independentsoft.onmicrosoft.com";
                client.ClientSecret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

                DateTime start = DateTime.Now;
                DateTime end = start.AddMonths(3);

                IList<Event> occurrences = await client.GetOccurrences("recurring-event-id-123", start, end);

                for (int i = 0; i < occurrences.Count; i++)
                {
                    Console.WriteLine("Subject = " + occurrences[i].Subject);
                    Console.WriteLine("Start = " + occurrences[i].Start?.DateTime);
                    Console.WriteLine("");
                }

                Console.Read();
            }
            catch (GraphException ex)
            {
                Console.WriteLine("Error: " + ex.Code);
                Console.WriteLine("Message: " + ex.Message);
                Console.Read();
            }
        }
    }
}

VB example

Imports Independentsoft.Graph
Imports Independentsoft.Graph.Calendars

Namespace Sample
    Class Module1
        Shared Sub Main(ByVal args As String())

            Dim task = New Task(AddressOf Run)

            task.Start()
            Console.Read()

        End Sub

        Shared Async Sub Run()
            Try

                Dim client As GraphClient = New GraphClient()

                client.ClientId = "63333333-209e-454e-b7bd-55a4d201270f"
                client.Tenant = "independentsoft.onmicrosoft.com"
                client.ClientSecret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

                Dim start As DateTime = DateTime.Now
                Dim [end] As DateTime = start.AddMonths(3)

                Dim occurrences As IList(Of [Event]) = Await client.GetOccurrences("recurring-event-id-123", start, [end])

                For i As Integer = 0 To occurrences.Count - 1
                    Console.WriteLine("Subject = " & occurrences(i).Subject)
                    Console.WriteLine("Start = " & occurrences(i).Start?.DateTime)
                    Console.WriteLine("")
                Next

            Catch ex As GraphException
                Console.WriteLine("Error: " & ex.Code)
                Console.WriteLine("Error: " & ex.Message)
                Console.Read()
            End Try
        End Sub

    End Class
