You can use a fifth (optional) argument for the PreProcess and PostProcess pragmas. If specified, this argument specifies which code regions the pragma must be applied to. This features adds greater precision and a lot of flexibility to these already powerful pragmas.
For example, let’s suppose that you have a Sub method named DoSomething and two Function methods named GetSomething and TestSomething. These three methods contain a local variable named “i” and you want to make the VB.NET code more readable by renaming this variable as “index”. You can achieve this by means of a single PostProcess pragma:
Unfortunately, this approach doesn't work well when converting to C#, because C# methods are closed by a generic curly brace rather than a more descriptive End Sub or End Function keyword.
