需求可以抽象为一个小例子，比如现在一个学生是一个对象，它具有学号这个属性，要求按照学号排序。
<p>首先写一个比较器，很简单：</p>
<pre lang="csharp">public class StudentComparer : IComparer
{
//实现按xuehao排序
public int Compare(Student x, Student y)
{
return (x.xuehao.CompareTo(y.xuehao));
}
}</pre>
<p>使用也很简单:</p>
<pre lang="csharp">
List<StuClass> stu = new List<StuClass>();
…………………
stu.Sort(new StudentComparer());
</pre>
</content>
