Get value after some specific character in C#

Question

So I want to extract the value from a string the value will place at the right after my specific character in this case my specific character is - and will place at the right.

The string will look like this:

TEST-QWE-1
TEST/QWE-22
TEST@QWE-3
TEST-QWE-ASD-4

And from that string I want to extract

1
22
3
4

How I do that in C#? Thanks in advance

Answer 1

mystring.Substring(mystring.IndexOf("-") + 1)

Or use LastIndexOf in case there are other dashes before the last part:

mystring.Substring(mystring.LastIndexOf("-") + 1)
