C#实现Ruby的负数索引器
public class InvertibleList<T> : List<T>
{
public new T this[int index]
{
get
{
if (index >= 0) return base[index];
if (Count + index < 0)
throw new IndexOutOfRangeException();
return this[Count + index];
}
set
{
if (index >= 0)
base[index] = value;
else
{
if (Count + index < 0)
throw new IndexOutOfRangeException();
this[Count + index] = value;
}
}
}
}
</div>
使用方法:
InvertibleList<string> list=new InvertibleList<string>
{
"1",
"2",
"3",
"4",
"5",
};
list[-2] = "asd";
list.ForEach(Console.WriteLine);
</div>
代码很简单,使用也很方便,希望对大家学习C#能够有所帮助
</div>
