c# - 用于对集合列表进行排序的 Lambda 表达式

Question

我的输入在xml文件下面

<Employees>
  <Department Position="9">
   <Employee No="7" Status="True" />
   <Employee No="6" Status="True" />
   <Employee No="8" Status="True" />
</Department>
<Department Position="4">
  <Employee No="7" Status="True" />
  <Employee No="8" Status="True" />
  <Employee No="6" Status="True" />
</Department>
</Employees>

Out put should  be  sorted  by department position  and  employee  "No"


<Employees>
 <Department Position="4">
  <Employee No="6" Status="True" />
  <Employee No="7" Status="True" />
  <Employee No="8" Status="True" />
 </Department>
 <Department Position="9">
   <Employee No="6" Status="True" />
   <Employee No="7" Status="True" />
   <Employee No="8" Status="True" />
 </Department>  

我添加了下面的代码，但它要么返回“position”明智的，要么返回“No”明智的，但不会同时返回两者。

var sortSignalList = new Dictionary<int, List<string>>();

sortSignalList.OrderBy(x => x.Position).OrderBy(x=>x.No).ToList();

Answer 1

sortSignalList.OrderBy(x => x.Position).ThenBy(x=>x.No).ToList();
