4.System.Collections命名空间中的列表接口（IList）
***field: bool IsFixedSize{get;}
***field: bool IsReadOnly{get;}
***indexer: object this[int index]{get;set;}//索引器
(indexer)是这样一个成员：它支持按照索引数组的方法来索引对象。索引器的声明与属性类似，不同的是该成员的名称是this，后跟一个位于定界符[和]之间的参数列表。在索引器的访问器中可以使用这些参数。与属性类似，索引器可以是读写、只读和只写的，并且索引器的访问器可以是虚的。
***interface method: int Add(object value);
***interface method: void Clear();
***interface method: bool Contains(object value);
***interface method: int IndexOf(object value);
