Yes, GetTempPath() should return a temporary file path, and the code you have posted should work. http://msdn.microsoft.com/en-us/library/system.io.path.gettemppath.aspx has more information about how GetTempPath() get's the path.

Though, it does not verify if the Temp Path directory exists, or is writeable by the application. I haven't run into a situation where GetTempPath() does return an inaccessible path. You'd probably want to account for this in your application to handle this situation.

Also be mindful, this is very possibly C:\Windows\Temp. It could have limited disk space, or deleted at any time by someone else when disk space is needed. You may want to create a temp path within your application, and delete it when you no longer need it.
