I have a string with two or more numbers. Here are a few examples:
"(1920x1080)"
" 1920 by 1080"
"16 : 9"
How can I extract separate numbers like "1920" and "1080" from it, assuming they will just be separated by one or more non-numeric character(s)?
The basic regular expression would be:
[0-9]+
You will need to use the library to go over all matches and get their values.
var matches = Regex.Matches(myString, "[0-9]+");
foreach(var march in matches)
{
// match.Value will contain one of the matches
}
You can get the string by following
MatchCollection v = Regex.Matches(input, "[0-9]+");
foreach (Match s in v)
{
// output is s.Value
}
RegexOptions.IgnoreCase is not needed. Roman numerals don't have upper/lower cases.(\d+)\D+(\d+)
After that, customize this regex to match the flavour of the language you'll be using.
\d will contain all digits, not only roman numerals, depending on regex library and platform.
\d matches [0-9]. Period.
I, II, ... VII etc. Aren't 0-9 Arabic?you can use
string[] input = {"(1920x1080)"," 1920 by 1080","16 : 9"};
foreach (var item in input)
{
var numbers = Regex.Split(item, @"\D+").Where(s => s != String.Empty).ToArray();
Console.WriteLine("{0},{1}", numbers[0], numbers[1]);
}
OUTPUT:
1920,1080
1920,1080
16,9
