Question

I need to parse the following format @[Alphanumeric1](Alphanumeric2:Alphanumeric3) from a long string. Below is my string:

This is a long text 
@[Alphanumeric1](Alphanumeric2:Alphanumeric3) again long text 
@[Alphanumeric11](Alphanumeric22:Alphanumeric33) again long text
@[Alphanumeric111](Alphanumeric222:Alphanumeric333) 

I need all the occurence of(@[Alphanumeric1](Alphanumeric2:Alphanumeric3)) to be replaced by value which is coming after colon(:) i.e I want the output as

This is a long text 
Alphanumeric3 again long text 
Alphanumeric33 again long text
Alphanumeric333 

Answer 1

This should do the trick:

class Program
{
    static void Main(string[] args)
    {
        string data = @"This is a long text 
@[Alphanumeric1](Alphanumeric2:Alphanumeric3) again long text 
@[Alphanumeric11](Alphanumeric22:Alphanumeric33) again long text
@[Alphanumeric111](Alphanumeric222:Alphanumeric333)";

        Debug.WriteLine(ReplaceData(data));
    }

    private static string ReplaceData(string data)
    {
        return Regex.Replace(data, @"@\[.+?\]\(.*?:(.*?)\)", match => match.Groups[1].ToString());
    }
}
