The Name property of the FileInfo class will return the filename and extention withouth the path.

System.String sPathAndFile = "c:\temp\filename.txt";
System.String sJustName;
FileInfo oFileInfo = new FileInfo(cFileName);
sJustName = oFileInfo.Name;

Now this isn't exactly a one-liner but this is: <s>

System.String sPathAndFile = "c:\temp\filename.txt"; System.String sJustName; FileInfo oFileInfo = new FileInfo(cFileName); sJustName = oFileInfo.Name;

Hope this helps
