I want to remove special characters from File name without affecting extension in c#

I have a file name let's say o example - Hello%@Im&an#Full-Stack+.Developer.pdf

I want to replace all the special characters from the file name with underscore _ and the result should be something like that.

Hello__Im_an_Full_Stack_Developer.pdf

Can anyone help me in making the regex for this task, my current regex is this [^\.\w]
