No, but there are at least a couple of workarounds:
1. You can always delete the mapping first, that causes no harm if it doesn't exist i.e.
cmd /c net use y: /del
2. In .Net you could check to see if the drive mapping exists e.g. use the DriveInfo class, if it doesn't throw an error trying to get info for Y: then it already exists
