Question

我创建了一个Azure活动目录用户，并将用户添加到了app角色。现在我正在检索此用户并尝试将其添加到更多应用程序角色。

var activeDirectoryUser = client.Users.Where(u => u.UserPrincipalName == user.UserName).ExecuteSingleAsync().Result as User;

作为预防措施，我想在添加之前首先检查用户是否已经处于app角色，但问题是ApproleAssignments对象上的User字段始终为空。即使您用户具有应用程序角色分配，如果我尝试将用户添加到相同的应用程序角色，我也会收到错误。

创建新的应用角色分配。

var appRoleAssignment = new AppRoleAssignment
{
    Id = appRole.Id,
    ResourceId = Guid.Parse(servicePrincpal.ObjectId),
    PrincipalType = "User",
    PrincipalId = Guid.Parse(user.ObjectId)
};

if(IsUserInAppRole(user,appRoleAssignment))return;

user.AppRoleAssignments.Add(appRoleAssignment);
user.UpdateAsync().Wait();

检查用户是否处于应用角色。

private bool IsUserInAppRole(User user, AppRoleAssignment appRoleAssignment)
{
    var userInApprole = user.AppRoleAssignments.Where(ara => ara.ObjectId == appRoleAssignment.Id.ToString());
    return userInApprole.Any();
}

我正在使用最新版本的Microsoft.Azure.ActiveDirectory.GraphClient库

对于迟到的回复感到抱歉。以下代码对我有用。不确定是否需要使用IUserFetcher接口，但LINQ查询失败，因为您正在将赋值的objectID与appRole Id进行比较。您需要比较的是作业的ID。

var userFetcher = user as IUserFetcher;
IPagedCollection<IAppRoleAssignment> rawObjects = userFetcher.AppRoleAssignments.ExecuteAsync().Result;

IList<IAppRoleAssignment> assignments = rawObjects.CurrentPage.ToList();
IAppRoleAssignment a = null;
a = assignments.Where(ara => ara.Id.Equals(appRole.Id)).First();
if (a != null) {
    Console.WriteLine("Found assignment {0} for user {1}", appRole.Id, user.DisplayName);
}

希望这会有所帮助......

Answer 2

var userFetcher = user as IUserFetcher; 
IPagedCollection rawObjects = userFetcher.AppRoleAssignments.ExecuteAsync().Result;
IList<IAppRoleAssignment> assignments = rawObjects.CurrentPage.ToList();

上面的代码行导致异常，因为如果将其转换为：

IPagedCollection rawObjects = 
         (IPagedCollection)userFetcher.AppRoleAssignments.ExecuteAsync().Result;

IList<IAppRoleAssignment> assignments = 
         (IList<IAppRoleAssignment>)rawObjects.CurrentPage.ToList();

代码已成功编译，但运行时异常为：

无法将类型'System.Collections.Generic.List'隐式转换为'System.Collections.Generic.IList'。存在显式转换（您是否错过了演员？）

请您指导如何使用这两个陈述？

<强>更新

private static bool IsUserInRole(User user, AppRole appRole, bool roleAlreadyAssigned = false)
        {
        var userFetcher = user as IUserFetcher;
        IPagedCollection rawObjects = (IPagedCollection)userFetcher.AppRoleAssignments.ExecuteAsync().Result;

        foreach (IAppRoleAssignment item in rawObjects.CurrentPage)
            {
            if (item.Id == appRole.Id)
                {
                roleAlreadyAssigned = true; break;
                }

            }
        return roleAlreadyAssigned;
        }

以上代码对我有用。试试这个，希望这会有所帮助：）
