C # basic introduction -- C # comments,

Annotation is some "descriptive text" in the code ". Annotations are not involved in program compilation and running, and are only for programmers to read.

 

Comments can be divided into single-line comments, multi-line comments, and document comments.

 

The symbol for a single line comment is two slash "//", and the content on the right of the two slashes is the comment, and the Code on the left is not affected.

 

Multi-line comments start with "/*" and end with "*/". The content between comments can contain multiple rows.

 

A document comment is written before a class, method, or attribute. It is marked with three slash "//".

 

1 namespace Test 2 {3 /// <summary> 4 // This class implements "hello" (document comment) 5 /// <summary> 6 class Program 7 {8 static void Main (string [] args) 9 {10/* 11 * Below is the variable declaration 12 * the second line is the output 13 * (multi-line comment) 14 */15 string name = "Mary "; // name (single line comment) 16 Console. writeLine ("My name is" + name); 17} 18} 19}

 

Note: The Console. WriteLine () in the Code is different from the previous Console. Write (). The latter does not wrap, and the former will wrap after printing.
