Csharp 从应用程序图API调用访问所有者字段

我有一个名为100的应用程序注册，以下用户为所有者:

在使用服务主体身份验证时，请确保分配Application.Read.All和User.Read.All个Application类型的权限.

在我的例子中，我使用下面的示例代码列出了应用程序所有者及其显示名称，并成功地获得了response个，如下所示:

using System;
using System.Threading.Tasks;
using Azure.Identity;
using Microsoft.Graph;
using Microsoft.Graph.Models;
using Microsoft.Graph.Models.ODataErrors;

class Program
{
    static async Task Main(string[] args)
    {
        var scopes = new[] { "https://graph.microsoft.com/.default" };

        var clientId = "appId";
        var tenantId = "tenantId";
        var clientSecret = "secret";

        var options = new ClientSecretCredentialOptions
        {
            AuthorityHost = AzureAuthorityHosts.AzurePublicCloud,
        };

        var clientSecretCredential = new ClientSecretCredential(
            tenantId, clientId, clientSecret, options);

        var graphServiceClient = new GraphServiceClient(clientSecretCredential, scopes);

        try
        {
            var owners = await graphServiceClient.Applications["appObjId"].Owners.GetAsync(requestConfiguration =>
            {
                requestConfiguration.QueryParameters.Select = new string[] { "id", "displayName", "givenName" };
            });

            foreach (var owner in owners.Value)
            {
                var user = (User)owner;
                Console.WriteLine($"Id: {user.Id}, Display Name: {user.DisplayName}, Given Name: {user.GivenName}");
            }

        }
        catch (ODataError odataError)
        {
            Console.WriteLine(odataError.Error.Code);
            Console.WriteLine(odataError.Error.Message);
        }
    }
}

Response:个

如果您使用委派流，则需要分配Application.Read.All和User.Read.All个Delegated类型的权限.
