Anyone keen to show me how to get the integer part from this string using c#?
string url = "/{localLink:1301}";
I've been into using something like this but didn't get it to work properly
var getNumeric = new Regex(".*([0-9]+)");

Your expression could be as simple as \d+, given the assumption that there will be only one number in your input. Still under that assumption, using ToString on the resulting Match will give you what you are looking for.
var regex = Regex.Match("/{localLink:1301}", @"\d+");
var result = regex.ToString();

Your .* is greedy. you either need .*? or [^\d]*
new Regex( ".*?(\d+)" );

Why shouldn't the match be greedy? You want to capture all of the numbers, not just the first one.

@vcjones, you want the numeric part to be greedy, not the part leading up to the numeric part. the
.* before the [0-9]+ was matching the first 3 numeric digits since . matches any character.you can try this....
string output = new string(input.ToCharArray().Where(c => char.IsDigit(c)).ToArray());
