The decorator pattern dynamically attaches responsibility to the object. To extend functionality, decorators provide a more flexible alternative than inheritance.
Implementation points
Category: Software Design
Software design is based on the software requirements specification, designing the overall structure of the software system, dividing functional modules, determining the implementation algorithm of each module, and writing specific codes according to the functions determined in the requirements analysis stage to form a specific software design plan. Software design abstracts many things and problems, and abstracts them at different levels and angles. Decomposing a problem or thing and modularizing it makes it easy to solve the problem. The finer the decomposition, the greater the number of modules. Its side effect is to make the designer consider more coupling between modules
Algorithm – The minimum spheres of the triangle in 3D?
First, I think you add the vertex and the scale by 1/3 to find the origin and then the maximum distance from the vertex to the origin. This will produce a sphere containing triangles, but it doesn’

System.net: In addition to NetWorkcredential, is there other classes that inherit from Icredentials?
In addition to NetworkCredential, are there other classes in the standard .Net library that inherit from ICredentials?
Maybe not only in the System.Net namespace.
It seems that the MSDN site
OOP – UML inheritance – Why is the arrow direction from subclass to the parent class?
In the above image, class B inherits class A. If B inherits all methods of A, shouldn’t the arrow go from A to B? In my opinion, if the arrow is from A to B, it will make more sense.
Is there

1. OCP–open close principle is the The cornerstone of “reuse design”. The “open” in the opening and closing principle means that the expansion of the component function is open. When the de
