Comment in C# Shortcut

In the C# programming language, comments are used to annotate the code to explain the logic and intention behind certain blocks of code. This is especially useful for documentation purposes and for explaining complex parts of the program to other developers. This article discusses how to use shortcuts for commenting in C# within the Visual Studio IDE.

Types of Comments in C#

C# supports both single-line and multi-line comments:

  • Single-line comments start with //. Everything from // to the end of the line is considered a comment.
  • Multi-line comments start with /* and end with */. Everything between /* and */ is considered a comment.

Using Shortcuts for Commenting

Visual Studio Shortcuts

In Visual Studio, you can quickly comment or uncomment code using the following shortcuts:

  • Commenting a line or selected block: To comment out one or more lines of code, you can use the shortcut Ctrl + K, Ctrl + C.
  • Uncommenting a line or selected block: To remove comments from one or more lines of code, use the shortcut Ctrl + K, Ctrl + U.

Example of Using Shortcuts

Here is how you can use these shortcuts in your coding workflow:

  1. Select the code: Use your mouse or keyboard to select the lines of code you want to comment or uncomment.
  2. Apply the shortcut:
    • To comment, press Ctrl + K followed by Ctrl + C.
    • To uncomment, press Ctrl + K followed by Ctrl + U.

Benefits of Using Shortcuts

Using keyboard shortcuts for commenting in Visual Studio offers several benefits:

  • Efficiency: Quickly toggle comments without removing your hands from the keyboard.
  • Cleaner code: Easily manage code readability and debugging by commenting out code blocks that are not needed or are under testing.


Mastering the use of shortcuts for commenting in C# can significantly speed up your development process and make code management more efficient. Whether you are debugging or explaining your code, these shortcuts are invaluable tools in any C# developer's arsenal.
