C# ignore windows string path only get filename

Question

how to copy the same string and ignore the file directory path?

Like Below:

  "C:\\Desktop\\Username\\filename\\filename"
  "D:\\Username\\filename\\filename\\filename"
  "E:\\Filename\\filename\\filename\\filename"

The Example:

string file = dialog.FileName;
string getfile = file;

if(file.Contains("Dangerous"))  // Check the file Contains these word
{
    string getfilename = file.Substring(3);   //with this only available ignore C:\\ or D:\\
}

Output:

Dangerous_2018_09_10_1.csv

Please share any clue with me, Thanks.

If you mean "drop all of the directory parts", then [Path.GetFileName](https://learn.microsoft.com/en-us/dotnet/api/system.io.path.getfilename) ? — Rup, Oct 08 '18 at 09:34
@Victor which means you want the *file name*. Use `Path.GetFileName`. There's no `file import path`, that's the directory path. — Panagiotis Kanavos, Oct 08 '18 at 09:38
@PanagiotisKanavos yes is directory path i update the question, thank you for your remind. — Comsphere, Oct 08 '18 at 09:40

Updated after the comment of @PanagiotisKanavos. This is probably the best way.

var fileName = File.GetFileName(file);

It could also be achieved this way, but use above if your only intention is to get the filename.

var myFileInfo = new FileInfo(file);
var fileName = myFileInfo.Name;

@Victor not really, unless you really need a `FileInfo` object. `Path.GetFileName` works without allocating an extra object – Panagiotis Kanavos Oct 08 '18 at 09:46
@PanagiotisKanavos: agreed, `Path.GetFileName()` is a better and shorter way to do this. – Sander Declerck Oct 08 '18 at 09:47
@ Panagiotis Kanavos use path.GetFileName will solve it too, thanks for the sharing. – Comsphere Oct 08 '18 at 09:48
