Question

I need to extract the path info using Path.GetFileName(), and this function doesn’t work when the last character of the input string is DirectorySeparatorChar(‘/’ or ‘\’).

I came up with this code, but it’s too lengthy. Is there a better way to go?

string lastCharString = fullPath.Substring (fullPath.Length-1);
char lastChar = lastCharString[0];

if (lastChar == Path.DirectorySeparatorChar) {
    fullPath = fullPath.Substring(0, fullPath.Length-1);
}

Answer 1

fullPath = fullPath.TrimEnd(Path.DirectorySeparatorChar);
