Comments: Annotating the Code
You have already seen single-line comments, so here I'll discuss the second type of inline com-
ments—
delimited comments
—and mention a third type called documentation comments.
Delimited comments
have a start marker and an end marker.
Text between the matching markers is ignored by the compiler.
Delimited comments can span any number of lines.
For example, the following code shows a delimited comment spanning multiple lines.
↓
Beginning of comment spanning multiple lines
/*
This text is ignored by the compiler.
Unlike single-line comments, delimited comments
like this one can span several lines.
*/
↑
End of comment
A delimited comment can also span just part of a line. For example, the following state-
ment shows text commented out of the middle of a line. The result is the declaration of a single
variable,
var2
.
Beginning of comment
↓
int /*var 1,*/ var2;
↑
End of comment
■
Note
Single-line and delimited comments behave in C# just as they do in C and C++.
