如何在C Sharp中通过Graph API获取Microsoft个人资料图片

using Microsoft.Identity.Client;
using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        string clientId = "YourClientId";
        string clientSecret = "YourClientSecret";
        string tenantId = "YourTenantId";
        string graphApiEndpoint = "https://graph.microsoft.com/v1.0/me/photo/$value";

        var app = ConfidentialClientApplicationBuilder.Create(clientId)
            .WithClientSecret(clientSecret)
            .WithAuthority($"https://login.microsoftonline.com/{tenantId}")
            .Build();

        var scopes = new[] { "User.Read" };

        var result = await app.AcquireTokenForClient(scopes).ExecuteAsync();

        using (var httpClient = new HttpClient())
        {
            httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken);

            var response = await httpClient.GetAsync(graphApiEndpoint);

            if (response.IsSuccessStatusCode)
            {
                // 处理获取到的个人资料图片
                var imageBytes = await response.Content.ReadAsByteArrayAsync();
                // ...
            }
            else
            {
                Console.WriteLine($"请求失败: {response.StatusCode}");
            }
        }
    }
}
