Extended class methods

• Create a class named Myhelper that conventions methods in this class are extension methods. Note that this class must be a static class
• The extension method must be a static method
• The first parameter is the type to be expanded, the preceding callout this
• If Myhelper is in a class library, remember to add a reference to it and use the related namespace

Example:

Ways to extend the bool type

Public static string tochineses (this bool helper)
{
return helper? " true ": " false ";
}

< Span style= "color: #800000;" > direct when used: false. Tochineses ()

The Boolean does not have a tochineses () method, and this method is followed by the previous extension.
