Any language learning, the first to have an editor or integrated development tools IDE, otherwise the code does not know where to write. For my small white, install an IDE is the best, because C language is also compiled language, after writing code,

First, IntroductionFrom today onwards we begin to talk about "structural" design patterns, "structural" design patterns are as follows: Adapter mode, bridge mode, decorative mode, combination mode, appearance mode, enjoy meta-mode, proxy mode. The

User-defined data type conversionsC # allows you to define your own data types , which means that some tools are required to support data conversion between your own data types . The method is to define a data type conversion as a member operator

The problem arises:When we use the abstract classes and interfaces of C #, we often encounter the following similar problems, broadly summarized as follows:(1) What are the essential differences and connections between abstract classes and
