  • If you want to get the file name extension of a file in UWP, you can use [StorageFile.FileType property](https://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.storagefile.filetype.aspx). – Jay Zuo Jun 03 '16 at 07:50

try this Path.GetExtension Method (String)

string ext = Path.GetExtension("FilePath");

Or you can simply use this 

string PathTofile = @"E:\POSAPP\POS\POS\bin\Debug\kjhs.exe";
string extension = PathTofile.Substring(PathTofile.LastIndexOf('.')+1, PathTofile.Length - PathTofile.LastIndexOf('.')-1);
