Ienumrator with example

IEnumerator是一个接口，在实现时允许您遍历控件列表.要实现它，您需要提供两种方法-重置以返回到列表的开头，移动下一步以向前移动，以及当前以获取当前项目. MSDN在此处提供了一个示例: http://msdn.microsoft.com/en-us/library/system.collections.ienumerator.aspx [ ^ ]
一旦为类实现了IEnumerable，它就可以成为foreach循环的目标.

IEnumerator is an interface, which when implemented allows you to iterate through the list of controls. To implement it requires that you provide two methods - Reset to go back to the beginning of the list, and MoveNext to move forward, and Current to get the current item. MSDN provides an example here: http://msdn.microsoft.com/en-us/library/system.collections.ienumerator.aspx[^]
Once you have implemented IEnumerable for your class, it can become the target of a foreach loop, among other things.

简单来说，Ienumerator是对集合的迭代(非-通用的).它是枚举器的基本接口.但是，枚举器可用于读取集合中的数据，而不能用于修改集合中的数据.因此，您可以自己思考并以身作则，以满足上述基本条件.试试看，让我们知道您是否被卡住.

In simple words Ienumerator is an iteration over a collection (non-generic). It is the base interface for enumerators. However, enumerators can be used to read data in a collection, and it cannot be used to modify the data in the collection. So you can think and example yourself to meet the above basic conditions. Give a try, and let us know if you are stuck.
