How to get file name from a path in c#

Question

I want to extract the filename from a file path in C#.

For example:

textBox1.Text = "C:\Users\Elias\Desktop\image.png"

I want to copy the file name: "image.png" to the textBox2

How can i do that?

No i didn't. I don't know what is "string api"! Because i'm new to C# — ilyas elouazzani, Mar 12 '17 at 01:05

Use the static Path.GetFileName method in System.IO:

Path.GetFileName(@"C:\Users\Elias\Desktop\image.png"); // --> image.png

regarding your example:

textBox2.Text = Path.GetFileName(textBox1.Text);

@ilyaselouazzani don't just say it didn't work, say what happened: Was there an error or just not the text you were expecting? – weston Mar 12 '17 at 01:29
Maybe it threw an error because the path was not formated properly – CaptainHere Mar 12 '17 at 01:58

System.IO.FileInfo class can help with parsing that information:

textBox2.Text = new FileInfo(textBox1.Text).Name;
