How can I substract the last element of a path in c#?

Question

I need to obtain in a new string the last element of a path. For ex, for the path

"C:\Users\MEDIACENTER\Desktop\Resurse_C#\Resurse\Imagini\Cluj1.txt"

I want to obtain "Cluj1.txt". Because I need a general method because I am working with a DataBase. The character '\' is the one that I have trouble with, because the C# syntax will not let me use it on the 3rd line of code:

01.    while (dr.Read()) // in dr[0] contains the jpg path
02.    {
02.           string v = dr[0].ToString();
03.           char c = '\'; 
04.           string[] s = v.Split(c);            
05.    }

Is this what you're looking for? `string filename = Path.GetFilename(dr[0]);` — Lasse V. Karlsen, Mar 02 '20 at 10:18
Note that `Path.GetFilename` can also be used to get the name of the last folder in a path that references a folder. Basically, `Path.GetFilename` does exactly what you're looking for, it is not limited to files, it will use the position of the last path separator and return everything after it. — Lasse V.

the '\' character is the escape character - if you want to specify the backslash character you need to use '\\'. For more info see [How do I write the escape character to code](https://stackoverflow.com/questions/15748040/how-do-i-write-the-escape-char-to-code) — Ian, Mar 02 '20 at 10:23
Thank you a lot for all of the information, the escape character made me a lot of problems and now I finally understood it! — Alex Lazar, Mar 02 '20 at 10:30

Have you tried Path.GetFileName

var filename = Path.GetFileName(@"C:\Users\MEDIACENTER\Desktop\Resurse_C#\Resurse\Imagini\Cluj1.txt");
