Get everything before dot or comma c#

Cieja Published in 2017-12-07 21:13:09Z

how can I get a substring of everything before dot or comma?

For example:

    string input = "2.1";
int charLocation = text.IndexOf(".", StringComparison.Ordinal);
    string test = input.Substring(0, charLocation );

but what if I have an input = "2,1" ?

I would like to do it in one method, not using twice a substring (once for dot and once for comma)?

string test = input.Split(new Char[] { ',', '.' })[0];

This will split the string for either comma or period...

Use the IndexOfAny function. It allows you to specify a list of characters to look for, rather than just a single character. You could then make a substring up to the return value of that function.


char[] chars = { '.', ',' }
String out = s.Substring(0,s.IndexOfAny(chars));
