C # Coding specifications summarized by myself-7. Download and summary of documents, Today, I finally finished writing this series of coding specifications. This coding specification was counted as reading relevant books. It took a whole month before and after that, and it was my painstaking work. I didn't plan to write this series so long, but I searched the relevant online materials during the writing pro

Learning GoalsThe second chapter is to learn character and string processing, in order to better understand the content of this chapter, I added additional auxiliary content: storage mode (big-endian storage and small-end storage), character encoding scheme (see it). The following are the learning objectives of this chapter:1. Big-endian storage and small-end sto

Here is a concrete example to illustrate:usingSystem;namespace teststatic{class statictest{intXStatic intYPublic statictest(int A,int b){x = A; y = b; }Public void simpleprint(){Console.WriteLine ("x="+x+", y="+y); }Public static void staticprint(){Console.WriteLine ("Y={0}", y);//Console.WriteLine ("X={0}", x); Non-static members cannot be used in static methods} }class Test{ static void Main(string[] args){Statictest St =NewSt

Alloc and new use summary 1. New is seldom used in real-world development, generally creating objects we see all [[ClassName alloc] init] But it doesn't mean you won't be exposed to new, and you'll see [ClassName new] in some code,There is also the possibility of being asked this question when you go to an interview. 2. So, what's the difference between them? We look at the source:-------------------------------------------
