c# - Splitting a string from a specific point in C#

Question

I have looked at the split string methods in C#, such as:

string[] lines = Regex.Split(value, "\");

Although I have come across the situation where I need to extract a file name from a file path, so I dont want to have to split the string on all occurrences of "\" e.g.:

C:\Windows\System32\calc.exe

Expected output:

calc.exe

Answer 1

new FileInfo(@"C:\Windows\System32\calc.exe").Name

Answer 2

Let the framework take the strain. Use the Path.GetFilename method.
