List<T>类可以使用Sort()方法对元素排序。
Sort()方法定义了几个重载方法,分别是
public void List<T>.Sort(),不带有任何参数的Sort方法
public void List<T>.Sort(Comparison<T>),带有比较代理方法参数的Sort方法
public void List<T>.Sort(IComparer<T>), 带有比较器参数的Sort方法
public void List<T>.Sort(Int32,Int32,IComparer<T>),带有比较起参数,可以指定排序范围的Sort方法
第一种方法必须继承IComparable<>接口,下面是示例代码:
