solid design principles c#

successful than before, a large group of eager programmers are waiting for the opportunity to use it. Life is beautiful. An inch in size ...... Good days always go too fast. A few weeks later, the boss came to patronize you that morning. He said: customers sometimes want the copy program to output to the tape piercing machine. Customer! They always destroy your design. Writing software is much easier without customers. Once again, you warn

touch. It is important to note that the design principle is to allow us to choose among the many ideas more in line with our product ideas, rather than let us based on these principles to creative. Using design principles to screen out all kinds of ideas, this method works well. But if you stick to these

in the object-oriented solid principle, which is another way of this principle. There is also a principle called composition over inheritance (like combination rather than inheritance), which is the design principles in the 23 classic design patterns.

doesn't answer the fundamental object-oriented question-Why do we use object-oriented objects. How should we use the three mechanisms to achieve "good object-oriented". What kind of object-oriented principles should we follow? Any serious object-oriented programmer, such as a C # programmer, needs to systematically learn object-oriented knowledge and object-oriented knowledge from programming languages an

As we all know, design principles are the cornerstone of design patterns. When the design principles are followed, the written code becomes very flexible and can cope with changes and be easier to maintain. Of course, it is not so absolute. Next, we will briefly introduce so

deep understanding of the design mode and continue to hone it in practice. The pattern is less important than the OO principle. If you can design a program that basically complies with the above principles, you may have summarized a new pattern, therefore, the learning model aims to deeply understand oo ideas and principles
