#29 – Comments

Comments in a C# program denote text that is ignored by the compiler and therefore has no effect on the behavior of the program.

There are two types of comments in C#:

  • Single line comments:  start with //, extend to end of line
  • Delimited comments:  surrounded by /*  */, can span multiple lines

Examples:

 string s1 = "Hi";        // This is a single-line comment

 /*  Multiple line
  *  comment.  Nice convention to use
  *  asterisk at the start of each line. */

 string s2 = "/* This is a string, rather than a comment */";
 string s3 = "// same here";

 // Nested comments /* ignored */

 //--------------------------------------
 // Even better style for block comment
 //--------------------------------------
