Question

以下代码是核心工作人员服务项目，它更新不同租户的用户事件。
我已经使用了Graph服务客户端（Microsoft Graph .NET Client Library）。
更新事件针对不同的租户无限执行。
在那里，我需要避免在更新用户事件时每次以 UpdateMethod1（） 实例化 GraphServiceClient 。我添加了 UpdateMethod2（） 来为每个租户创建 GraphServiceClient 并将其存储在字典中。
是好的方法还是更好的解决方案？

public class Worker : BackgroundService
    { 
        ConcurrentDictionary<string, GraphServiceClient> graphServiceClientDictionary = new ConcurrentDictionary<string, GraphServiceClient>();
        private IConfidentialClientApplication _confidentialClientApp = ConfidentialClientApplicationBuilder.Create("XXXX-XXX-XXXX-XXXX-XXXXXXXXXX")
                                                                        .WithAuthority(AzureCloudInstance.AzurePublic, AadAuthorityAudience.AzureAdMultipleOrgs)
                                                                        .WithClientSecret("XXXX-XXXX")
                                                                        .Build();  

        protected override async Task ExecuteAsync(CancellationToken stoppingToken)
        {
            while (!stoppingToken.IsCancellationRequested)
            {
                _logger.LogInformation("Worker running Execute every 10 seconds", DateTimeOffset.Now);
                foreach (var message in GetMessagesFromDB())
                {
                    //await UpdateEvent1(message.tenantId, message.userId);
                    await UpdateEvent2(message.tenantId, message.userId);
                }               
                await Task.Delay(10000, stoppingToken);
            }
        } 

        private async Task UpdateEvent1(string tenantId, string userId)
        {
            GraphServiceClient graphClient = new GraphServiceClient(GetClientCredentialAuthProviderForTenant(tenantId, userId));
            var @event = await graphClient.Me.Events[userId]
                                .Request()
                                .UpdateAsync({ Body = DateTime.Now.ToString()});
        }

        private async Task UpdateEvent2(string tenantId, string userId)
        {
            GraphServiceClient graphClient;
            bool isClientExist = graphServiceClientDictionary.TryGetValue(tenantId, out graphClient);
            if (!isClientExist)
            {
                graphClient = new GraphServiceClient(GetClientCredentialAuthProviderForTenant(tenantId, userId));
                graphServiceClientDictionary.TryAdd(tenantId, graphClient);
            }
            var @event = await graphClient.Me.Events[userId]
                                .Request()
                                .UpdateAsync({ Body =  DateTime.Now.ToString()});
        }

        private IAuthenticationProvider GetClientCredentialAuthProviderForTenant(string tenantId, string userId)
        {
            return new  CustomClientCredentialProvider(_confidentialClientApp, tenantId);
        }
    }

重用GraphServiceClient实例
