关于.Net 排序

 

好久不碰這個了，僅此記錄下

1. 通過Lambda表達式

   Class Temp
   {
   Public int AA;
   }
   Temp t  as new Temp;
    t.Sort((a, b) => { return a.AA.CompareTo(b.AA); });

   Class Temp
   {
   Public int AA;
   }
   Temp t  as new Temp;
    t.Sort((a, b) => { return a.AA.CompareTo(b.AA); });

   //惡心的匿名方法
   t.AA.Sort(delegate(Temp a, Temp b)
   {
       return a.AA.CompareTo(b.AA);
   });

   //惡心的匿名方法
   t.AA.Sort(delegate(Temp a, Temp b)
   {
       return a.AA.CompareTo(b.AA);
   });
2. 使用IComparer接口

   public class TempComparison : IComparer<TEMP>
   {
       public int Compare(Temp x, Temp y)
       {
           return x.AA.CompareTo(y.AA);
       }
   }
   
   t.AA.Sort(new TempComparison().Compare);

   public class TempComparison : IComparer<TEMP>
   {
       public int Compare(Temp x, Temp y)
       {
           return x.AA.CompareTo(y.AA);
       }
   }
   
   t.AA.Sort(new TempComparison().Compare);
3. 使用LINQ

   var list = from c in t
              orderby c.AA ascending
              select c;

   var list = from c in t
              orderby c.AA ascending
              select c;
4. 当然可以通过实现IComparable 这种笨方法
