Find messages by received time

The following example shows you how to use the Query parameter to search for messages. Here we specify condition (Filter) to retreive messages received in the last hour and also with Select we specified which properties we want to retreive for every message.

C# example

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using Independentsoft.Graph;
using Independentsoft.Graph.Mails;
using Independentsoft.Graph.QueryOptions;

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

                client.ClientId = "67cb3333-209e-454e-b7bd-55a4d201270f";
                client.Tenant = "independentsoft.onmicrosoft.com";
                client.Username = "info@independentsoft.onmicrosoft.com";
                client.Password = "password";

                IsGreaterThanOrEqualTo condition = new IsGreaterThanOrEqualTo(MessagePropertyName.ReceivedTime, DateTime.Now.AddHours(-1));
                PropertyOrder orderBy = new PropertyOrder(MessagePropertyName.ReceivedTime, true);

                Query query = new Query();
                query.Select.Add(MessagePropertyName.Id);
                query.Select.Add(MessagePropertyName.Subject);
                query.Select.Add(MessagePropertyName.ReceivedTime);
                query.Select.Add(MessagePropertyName.From);
                query.OrderBy.Add(orderBy);
                query.Filter = condition;
                query.Top = 999;

                IList<Message> messages = await client.GetMessages(query);

                for (int i = 0; i < messages.Count; i++)
                {
                    Console.WriteLine("Id: " + messages[i].Id);
                    Console.WriteLine("Subject: " + messages[i].Subject);
                    Console.WriteLine("ReceivedTime: " + messages[i].ReceivedTime);
                    Console.WriteLine("From: " + messages[i].From.Address);

                    Console.WriteLine("---------------------------------------");
                }

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