如何欺骗Windows浏览对话框？

Question

I have an application where i use the windows browse dialog to select a file from the file system. The application is written in C#, silverlight. My requirement is that when i select any particular file from this dialog, the user should be restricted to selecting only a set of files with a particular extension. I have achieved this and the dialog only lists those files with the extension i permit. I am trying to break this by somehow letting the user select a file with a different extension from what is permitted. Is there a way to select a file from this dialog other than the one which is permitted ? Any user hacks ?

PS: i dont want to change any code. I need this only for testing purpose with an intention to break the functionality.

有一个非常简单的方法：用户只需在文件名框中键入*.* ，他就会看到所有文件。
