实体框架存储过程抛出“无法找到源类型'int'的查询模式的实现。'选择'未找到'。错误

Question

我在使用Entity Framework调用存储过程的类中有一个方法，并且它不断抛出错误

  

无法找到源类型“int”的查询模式的实现。 “选择”未找到。

但是，我在另一个类中使用完全相同的方法，并且它根本不会抛出任何错误。

有问题的方法就是这个..

public List<ActiveAdministratorsForUpdate> GetActiveAdministratorByID(int id)
{
    List<ActiveAdministratorsForUpdate> lst = new List<ActiveAdministratorsForUpdate>();
    var query = from a in AAE.usp_GetActiveAdministratorsByID(id)
                select a;

    foreach (var b in query)
    {
        lst.Add(new ActiveAdministratorsForUpdate
                    {
                       administratorID = b.AdministratorID,
                       administratorName = b.AdministratorName,
                       administratorPassword = b.UserPassword,
                       administratorEmail = b.AdministratorEmail,
                       administratorRole = b.RoleName,
                       administratorRoleID = b.RoleID });
    }

    return lst;
}

我正在做的是移动一些代码来处理我添加到项目中的另一个数据库。

public virtual int usp_GetActiveAdministratorsByID(Nullable<int> administratorID)
    {
        var administratorIDParameter = administratorID.HasValue ?
            new ObjectParameter("AdministratorID", administratorID) :
            new ObjectParameter("AdministratorID", typeof(int));

        return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction("usp_GetActiveAdministratorsByID", administratorIDParameter);
    }

这是存储过程
