Get drive item changes

The following example shows you how to use delta query to track changes to drive items.

C# example

using System;
using System.Threading.Tasks;
using Independentsoft.Graph;
using Independentsoft.Graph.Files;

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";

                DriveItemChanges changes = await client.GetDriveItemChanges();

                for (int i = 0; i < changes.DriveItems.Count; i++)
                {
                    Console.WriteLine("Name = " + changes.DriveItems[i].Name);
                    Console.WriteLine("Id = " + changes.DriveItems[i].Id);
                    Console.WriteLine("");
                }

                Console.WriteLine("DeltaLink = " + changes.DeltaLink);
                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.Files

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 changes As DriveItemChanges = Await client.GetDriveItemChanges()

                For i As Integer = 0 To changes.DriveItems.Count - 1
                    Console.WriteLine("Name = " & changes.DriveItems(i).Name)
                    Console.WriteLine("Id = " & changes.DriveItems(i).Id)
                    Console.WriteLine("")
                Next

                Console.WriteLine("DeltaLink = " & changes.DeltaLink)

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

    End Class
End Namespace
