C# 我可以从一个DataContext调用另一个DataContext中的方法吗？

我有下面的LINQ问题，我想补充一下护士的名字。不幸的是，它们存储在一个单独的数据库中，因此是一个单独的DataContext

如何从使用

cmodatacontext

的查询中调用

aspnetdbcontext

中的方法

这是aspnetdb中获取护士姓名的方法：

    internal static AspnetdbDataContext context = new AspnetdbDataContext();

    public static IList WorkerList(Guid userID)
    {
        IList theWorkers;
        using (context)
        {
            var workers = from user in context.tblDemographics
                          where user.UserID == userID
                          select new { user.FirstName, user.LastName, user.Phone };
            theWorkers = workers.ToList();
        }
        return theWorkers;
    }

    public static DataTable GetAllMembers(Guid workerID)
    {
        DataTable dataTable;

        using (context)
        {
            var AllEnrollees = from enrollment in context.tblCMOEnrollments
                               where enrollment.CMOSocialWorkerID == workerID || enrollment.CMONurseID == workerID
                               from supportWorker in context.tblSupportWorkers 
                               where supportWorker.SupportWorkerID == enrollment.EconomicSupportWorkerID
                               select
                                   new
                                       {
                                           enrollment.ADRCReferralID,
                                           enrollment.ClientID,
                                           enrollment.CMONurseID,
                                           enrollment.CMOSocialWorkerID,
                                           enrollment.DisenrollmentDate,
                                           enrollment.DisenrollmentReasonID,
                                           supportWorker.FirstName,
                                           supportWorker.LastName,
                                           supportWorker.Phone,
                                           enrollment.EnrollmentDate
                                       };

            dataTable = AllEnrollees.CopyLinqToDataTable();
        }
        return dataTable;
    }

这是我在CMO中调用的绑定到DataGridView的方法：

    internal static AspnetdbDataContext context = new AspnetdbDataContext();

    public static IList WorkerList(Guid userID)
    {
        IList theWorkers;
        using (context)
        {
            var workers = from user in context.tblDemographics
                          where user.UserID == userID
                          select new { user.FirstName, user.LastName, user.Phone };
            theWorkers = workers.ToList();
        }
        return theWorkers;
    }

    public static DataTable GetAllMembers(Guid workerID)
    {
        DataTable dataTable;

        using (context)
        {
            var AllEnrollees = from enrollment in context.tblCMOEnrollments
                               where enrollment.CMOSocialWorkerID == workerID || enrollment.CMONurseID == workerID
                               from supportWorker in context.tblSupportWorkers 
                               where supportWorker.SupportWorkerID == enrollment.EconomicSupportWorkerID
                               select
                                   new
                                       {
                                           enrollment.ADRCReferralID,
                                           enrollment.ClientID,
                                           enrollment.CMONurseID,
                                           enrollment.CMOSocialWorkerID,
                                           enrollment.DisenrollmentDate,
                                           enrollment.DisenrollmentReasonID,
                                           supportWorker.FirstName,
                                           supportWorker.LastName,
                                           supportWorker.Phone,
                                           enrollment.EnrollmentDate
                                       };

            dataTable = AllEnrollees.CopyLinqToDataTable();
        }
        return dataTable;
    }

我怎样才能把两者结合起来呢

谢谢

只需创建两个DataContext对象，在第一个数据上下文中检索对象中的数据，然后将该数据复制到另一个数据上下文中的新对象并提交更改（）
