difference between abstract class and interface in c#

(Source http://hi.baidu.com/dgx_lsyd3/blog/item/8f710ed7ca49badda144dfd0.html) ---------------------------------------------Explanation 1:Abstract class and interface are two mechanisms supported for the definition of abstract classes in Java. It is precisely because of the existence of these two mechanisms that give Java powerful object-oriented capabilities.

deep understanding of these two object-oriented basic content, for the enliven object-oriented abstract programming idea is very important. This article basically outlines the interface and abstract class concepts, similarities and differences and the use of rules, from a learning point of view, I think these summaries are enough to express its core. But with an

called interface pollution.10 try to avoid using inheritance to implement the build function, but instead use black box multiplexing, which is the object combination. Because of the increasing level of inheritance, the most immediate consequence is that when you call one of these classes, you have to load them all into the stack! The consequences are conceivable.11 If an abstract class implements an interf

The door (abstract class) defines what you are, and the interface (lock) specifies what you can do (an interface is best to do only one thi

This will deepen the understanding of knowledge. The interfaces and
