I'm going to change my comment to the correct answer, because after a quick game, what I suggested does exactly what you want.
Download the free version of Reflector from here , unzip it and run it. Drag the compiled version of your assembly onto it, and next to the Name tag in the information section at the bottom of the dialog box will be its full name, ready for you to simply copy and paste from there.
Please note that all the necessary information is also available by right-clicking on the compiled file, select Properties , then go to the Details tab, although you cannot just copy / paste from there.
