Post your code inside your question, not as a comment. Also, the error means what it says. Given the vast difference between the two types you mention, I suspect you're doing something insane in your code. Use your debugger. Read the code. Check the methods you're calling and their parameter types and return types. When the IDE tells you what line is blowing up, read that line, and TELL US WHAT IT IS if you need to ask for help.

I'd say this is the error:

DirectoryInfo dir = (DirectoryInfo)folderlist.SelectedItems;

Your selected items may be a collection of DirectoryInfo items, but they are a collection, not one object. The SelectedItem property might work here.

This is basic coding 101, I would suggest it's insane you're using paid for tools when you have no idea about basic programming. You should buy some basic books and read them.
