任何人都可以解释这行代码吗？

bool status = datacontext.tblTransactionDetails.Where(x => x.AdvertID == app.AdvertID && x.IsActive == true).FirstOrDefault() == null ? false : true;

foreach (var app in allList)
{
    int?[] ids = Context.tblTransactionDetails
        .Where(x => x.IsActive == true)
        .Select(x => x.AdvertID);
}
