{simple} Extracting Substrings from textbox

[Guest]

I've been looking at .substring and .trim methods and I still have a question about extracting substrings from a textbox. Basically the textbox contains the full path to a file ... for example C:\testfile.txt or ... C:\download\temp\dlls\testfile.dll
I want to be able to extract the file name from this textbox (and put it in a string) when I click a button. Can someone illustrate how to write this line of code?

War Eagle,

It's simple. Use the static GetFileName method on the Path class in the
System.IO namespace, like this:

// Get the filename.
string pstrFileName = System.IO.Path.GetFileName(textbox.Text);

Hope this helps.

This will work too.

FileInfo fInfo = new FileInfo(txtBox.text);
string fileName = fInfo.Name;
