如何使用Lambda表达式对对象中的INTEGERS进行排序？ [英] How do I use a Lambda expression to sort INTEGERS inside a object?

问题描述

我有一个对象集合，我知道我可以按NAME（字符串类型）通过

  collEquipment进行排序。 Sort（（x，y）=> string.Compare（x.ItemName，y.ItemName））; 
 
 
 
 
 
 $ b 
按照ID（整数类型）排序，没有Int32.Compare这样的东西
 
 
 
那么我该怎么做呢？这不起作用
  collEquipment.Sort（（x，y）=>（x.ID< y.ID ））; //错误
  
我知道答案会很简单。 Lambda表达式让我困惑。 
解决方案
试试这个
  collEquipment.Sort（（x，y）=> y.ID-x.ID）; 
  
 
I have a collection of objects and I know that I can sort by NAME (string type) by saying
collEquipment.Sort((x, y) => string.Compare(x.ItemName, y.ItemName));
that WORKS.

But I want to sort by a ID (integer type) and there is no such thing as Int32.Compare

So how do I do this?  This doesn't work
collEquipment.Sort((x, y) => (x.ID < y.ID));  //error
I know the answer is going to be really simple. Lambda expressions confuse me. 
解决方案
try this
collEquipment.Sort((x, y) => y.ID - x.ID);
