Chaning a file's extension

[mwcapps]

I'm writing an import application that import .csv files into my SQL Server 2005 database. When the import is complete I need to change that files extension from .csv to .imp with the same path. I've tried using the following:

FileSystem.Rena me(fullpathofol dfile, fullpathofnewfi le)
Microsoft.Visua lBasic.Rename(f oldfile, fullpathofnewfi le)
My.Computer.Fil eSystem.RenameF ile(foldfile, fullpathofnewfi le)

All attempts are giving back an error or 'Procedure or argument is invalid'. I have full access and permission to all files in all paths.

Hi, this might not be the most elegant solution, but it sure works:

Dim Path As String = "C:\"
Dim strFileName As String = "test.csv"
strFileName = strFileName.Replace(".csv", "")
My.Computer.FileSystem.RenameFile(Path & strFileName & ".txt", strFileName & ".imp")
