Pankaj Kumar ChoudharyPosted Apr 2, 2015, 11:56 PM
There are 3 different types of comments in c#.
(A) Single Line Comments
Ex.. // use for single line comments in C#.
(B) Multi Line Comments
Ex. /* use multi line comments in c#*/
(C) XML tags Comments
Ex. /// use to specify the XML comments in c#
Note - we can use Ctrl+K, Ctrl+C and Ctrl+K, Ctrl+U to Comment or Uncomment selected lines in C#.
Prem RanjanPosted May 19, 2014, 9:53 AM
1. Single Line Comment
The single line comment is specified using the symbol //
Eg:
// this is a AbundantCode comment
Popular Code Guidelines or Standard Documents for .NET Developers
2. Multi Line Comment
The Multiline comment can be specified using the symbol /* */
Eg:
/* This is a test
3. XML Comment
This is a special kind of comment which is generally used for API documentation. The symbol /// is used to specify the XML comment in C#
balaji badrinathPosted May 17, 2014, 3:54 AM
there are two types of comments in c#..
Single line
i.e // comment single line
and
multiple lines
i.e /* here multiple lines */
