With the last character search you can get the right result.

string path = "C:\\Program Files\\Program\\fatih.gurdal.docx";
string fileName = path.Substring(path.LastIndexOf(((char)92))+ 1);
int index = fileName.LastIndexOf('.');
string onyName= fileName.Substring(0, index);
string fileExtension = fileName.Substring(index + 1);
Console.WriteLine("Full File Name: "+fileName);
Console.WriteLine("Full File Ony Name: "+onyName);
Console.WriteLine("Full File Extension: "+fileExtension);

Output:

Full File Name: fatih.gurdal.docx

Full File Ony Name: fatih.gurdal

Full File Extension: docx
