How do I get the last four characters from a string in C#?

Question

Suppose I have a string:

"34234234d124"

I want to get the last four characters of this string which is "d124". I can use SubString, but it needs a couple of lines of code, including naming a variable.

Is it possible to get this result in one expression with C#?

Answer 1

mystring.Substring(Math.Max(0, mystring.Length - 4)); //how many lines is this?

If you're positive the length of your string is at least 4, then it's even shorter:

mystring.Substring(mystring.Length - 4);
