Given path not supported exception occured in file.copy method

Question

I've tried to copy the mainlist xml file to bin\Debug folder. But It throws exception. I've passed argument in console application like "C:\Users\gio.frog\Desktop\mainlist.xml" and used file.copy method like follows:

File.Copy(args[0], AppDomain.CurrentDomain.BaseDirectory + "sublist.xml",true);

I've seen some same exception example in stackoverflow but can't get the correct reason. How to copy to bin/debug folder.?

Try `Path.Combine(AppDomain.CurrentDomain.BaseDirectory + "sublist.xml");` — vendettamit, Mar 22 '16 at 13:32
You're assuming `AppDomain.CurrentDomain.BaseDirectory` ends with a \ which it may not, use `Path.Combine()`. — Lloyd, Mar 22 '16 at 13:33

The AppDomain.CurrentDomain.BaseDirectory returns path without \ at the end. When you combine it with a trying it will concatenate with directory name.

E.g. "c:\projects\Debug\bin" + "sublist.xml" will result in "c:\projects\Debug\binsublist.xml"

Use

Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "sublist.xml");
