Difference between // and /// in c#

Question

When I type ///, Visual Studio shows me some parameters like this:

/// <summary>
/// 
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>

What is the difference between // and /// in C#?

Answer 1

There is a big difference.

First: XML comments will be shown on tooltips and auto complete. Try writing XML comments and while writing the function notice how what you wrote in XML comments pops out while you type the function.

Second: you can easily use tools to generate complete documentation.

Answer 2

The // comments are normal comments while /// comments are generally called xml comments. They can be utilized to make detailed help document for you classes.
