如何使用Microsoft Graph或Office 365 REST API从outlook获取所有任务？

using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        string accessToken = "YOUR_ACCESS_TOKEN";
        string graphApiEndpoint = "https://graph.microsoft.com/v1.0/me/tasks";

        using (HttpClient client = new HttpClient())
        {
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);

            HttpResponseMessage response = await client.GetAsync(graphApiEndpoint);
            if (response.IsSuccessStatusCode)
            {
                string responseContent = await response.Content.ReadAsStringAsync();
                // 解析响应内容，处理任务数据
                Console.WriteLine(responseContent);
            }
            else
            {
                Console.WriteLine("请求失败：" + response.ReasonPhrase);
            }
        }
    }
}
