如何使用 Graph SDK 获取用户的邮箱设置

Question

我在尝试使用此处的 Graph 客户端库获取此数据时遇到问题：https://www.nuget.org/packages/Microsoft.Graph in my c# application. I'm aware that the data is available using this REST API call。

我已经创建了我的 Azure 应用程序并提供了应用程序 "Read all user mailbox settings" 权限并单击 "grant permissions" 以应用它们。问题不在于我的身份验证。我能够检索数据。

MicrosoftAuthenticationProvider authProvider = 
    new MicrosoftAuthenticationProvider(applicationID, applicationSecret, microsoftURL);
GraphServiceClient graphClient = new GraphServiceClient(authProvider);
IGraphServiceUsersCollectionPage users = await graphClient.Users.Request().GetAsync();
foreach (User user in users)
{
    //user.MailboxSettings
    //returns null, but through intellisense, I can obtain it's attributes
    //Microsoft.Graph.MailboxSettings is available in the library's object browser

    //graphClient.Users[user.UserPrincipalName].MailboxSettings.Request().GetAsync() 
    //User.MailboxSettings is not available
}

作为最后的手段，我将使用 REST API，但如果可以的话，我只想使用库。

只需将 Select("MailboxSettings") 添加到您的查询中即可。

根据您的代码获取用户的邮箱设置

                IGraphServiceUsersCollectionPage users = await 
                    graphClient.Users.Request().GetAsync();

                foreach (User user in users)
                {
                    User fullUser = await graphClient.Users[user.UserPrincipalName].Request().Select("MailboxSettings").GetAsync();

                    MailboxSettings mailboxSettings1 = fullUser.MailboxSettings;                     
                }
