While experimenting with code, it can be very useful to comment a block of code temporarily.
To comment a block of code, use select Toggle Line Comment(s) from the context menu, or use the Control-Alt-C keybinding on Windows and Linux. If the current line is commented, it will be uncommented, or if it is not commented, it will be commented. If multiple lines are selected, then if any are not commented, they will all be commented. If all are commented, they will all be uncommented.
For C# files, this feature uses line comments, and if lines that are already commented are commented as part of a larger block, it adds another “level” of line comments onto those lines. This is useful, because it means that a region of code can be commented then uncommented, and actual comments within it will be preserved.
If you prefer to use multiline comments or
#if false directives, you can use
“surround with” templates, which will be covered tomorrow.
