C#: Selecting currently active file

Question

So I'm trying to create an add-in for Visual Studio 2012 and I'm stuck. So here's where I'm stuck.

Let's say in Visual Studio I'm working on a file. Assume it's called Default.aspx . My add-in works like this: When you press the button on the toolbar, it will copy everything on the file to a string variable and do some stuff with it.

So which function can I use to find the path of the current open file? I could have 4-5 tabs open in visual studio but I only want to find the path of the file which is currently being worked on which would be Default.aspx in this context. Is there a way to do this?

If you are using Desktop application you can try
var lstFormCollection = Application.OpenForms;--Will return all active page

In web
string currentPageFileName = new FileInfo(this.Request.Url.LocalPath).Name;
----Will return current page only

You want to use the application parameter, cast as an _DTE class:

C#

applicationObject = (_DTE)application;

You can then use the ActiveDocument[^] Property.

"Couldn't really understand your answer could you elaborate?"

When you write an addin, VS calls your method, and provides a number of parameters: one of these is the application as an object.
(see this, it might help: How to Create a Visual Studio Add-in that Launches from the Project Window[^])

You need to cast that object to a _DTE, and you can then access the ActiveDocument property - should give you access to your Default.aspx file.
