Question

The “this” that we use in Form application. What does it correspond to in WPF? Is it MainWindow? I am using a library that is build around Form application and there are alot of “this” and I don’t know how to convert the “this” in WPF

Answer 1

In C#, this is always a reference to the current instance of the class in which it is used.

In fact, to quote from MSDN:

The this keyword refers to the current instance of the class.

The following are common uses of this:

• To qualify members hidden by similar names

• To pass an object as a parameter to other methods

• To declare indexers

Examples can be found following the link above.

There is an exception to this rule when working with extension methods, however, where this is a modifier to the type of object by which the extension method is to be exposed.
