Question

When I use any .NET methods, there is a little hint (IntelliSense) which explains the methods and their parameters.

How do I achieve the same behaviour for my own methods?

Is there a Visual Studio feature which allows me to add these in?

Answer 1

the “feature” is called XML comments. Just type /// right before your methods and VS will generate some xml tags. These will be used to show the tooltip as well as parameter info aso.

/// <summary>
/// this will be the tooltip
/// </summary>
/// <param name="args">args will be passed when starting this program</param>
static void Main(string[] args)
{

}

Screenshot of my VS2010 when calling method add. As you can see, xml comments are shown.
