Enumerable range in descending order
提问by Pierre-Luc Pineault
I am binding a combobox using enumerable.range()and it works fine.
Now I am trying to display the results in descending order, how can I do that?
我正在使用绑定一个组合框enumerable.range()，它工作正常。现在我试图以降序显示结果，我该怎么做？
cboYearList.ItemsSource = Enumerable.Range( DateTime.Today.Year,1950).ToList().OrderByDescending();
回答by Pierre-Luc Pineault
You can Reversethe list after creating it with Enumerable.Range:
您可以使用Reverse以下命令创建列表Enumerable.Range：
cboYearList.ItemsSource = Enumerable.Range(DateTime.Today.Year, 1950).Reverse().ToList();
Or if you want to keep your OrderByDescending, you need to pass a key selector (the i => iat the end):
或者如果你想保留你的OrderByDescending，你需要传递一个键选择器（i => i在最后）：
cboYearList.ItemsSource = Enumerable.Range( DateTime.Today.Year,1950).OrderByDescending(i => i).ToList();
