Interface allows an inheriting class to implement a parameter class , which represents a parameter to a command object 接口允许继承类实现parameter类，表示command对象的参数。
Interface allows an inheriting class to implement a dataadapter class , which represents the bridge between a data source and a 接口允许继承类实现dataadapter类，该类表示数据源与
Interface allows an inheriting class to implement a tablemapping class , which associates a data source column with a 接口允许继承类实现tablemapping类， tablemapping类将数据源列与
When overridden in a derived class , adds the attributes of the inheriting class to the specified list of attributes in the parent class 当在派生类中被重写时，将继承类的属性添加到父类中指定的属性( attribute )列表。
For instance , microsoft compiler uses process - neutral offsets to address base objects for virtually inherited classes : thus , this issue does not arise 例如， microsoft compiler使用进程无关的偏移量来为虚拟继承类指定基对象，因而不存在这个问题。
Can be used to find inherited components , select which ones to ignore , and retrieve the inheritance attribute of each inherited class that is tracked by the service 可用于查找继承的组件、选择要忽略的组件，以及检索该服务跟踪的每个继承类的继承属性。
Interface enables an inheriting class to implement a connection class , which represents a unique session with a data source for example , a network connection to a server 接口允许继承类实现connection类，该类表示与数据源之间的唯一会话（例如，到服务器的一个网络连接） 。
Generic classes that inherit from open constructed types must supply type arguments for any base class type parameters that are not shared by the inheriting class , as demonstrated in the following code 从开放式构造类型继承的泛型类必须为任何未被继承类共享的基类类型参数提供类型变量，如以下代码所示：
In generally , we can say that anytime u redefine an overloading function name from the base class , all of the other versions are automatically hidden in the new class 总结为：继承类把基类的重载函数重定义后，只能调用继承类对象的已重定义的函数，而不是调用基类的那些重载函数（同名函数） ，即在继承类中基类的重载函数被隐藏！
