Question

我已经咨询了Warning in Resharper "Return value of pure method is not used"帖子但未找到解决方案

看看我的代码

var listDetail = (from p in Expense.GetAll()
    where p.Group == "001"
    select new ExpenseViewModel()
    {
        ExpenseC = p.ExpenseC,
        Group = p.Group,
        Cost = p.Cost,
    }).ToList();
listDetail.OrderBy(p => p.ContainerSizeI); //warning displayed at OrderBy with content "return value of pure method not used"

因此，listDetail变量没有按照我想要的升序排序

Answer 1

您需要将OrderBy移动到您的方法链中。

var listDetail = (from p in Expense.GetAll()
where p.Group == "001"
select new ExpenseViewModel()
{
    ExpenseC = p.ExpenseC,
    Group = p.Group,
    Cost = p.Cost,
})
.OrderBy(p => p.ContainerSizeI)
.ToList();

排序列表时OrderBy不起作用，Resharper也显示警告“未使用纯方法的返回值”
