Question

我如何得到這個正常工作不工作？我想order by duedate desc, type

我目前有：

billSummaryRepository.GetBillSummaries(logIn.CustomerNumber) 
    .OrderByDescending(o => o.DueDate) 
    .OrderBy(o => o.Type) 

這工作：

BillSummaries = billSummaryRepository.GetBillSummaries(logIn.CustomerNumber) 
    .OrderBy(o => o.Type) 
    .OrderByDescending(o => o.DueDate) 

而且是多麼危險？它會起作用嗎？

Answer 1

BillSummaries = billSummaryRepository 
    .GetBillSummaries(logIn.CustomerNumber) 
    .OrderByDescending(o => o.DueDate) 
    .ThenBy(o => o.Type);
