New Methods for existing types?

OOP way to augment functionality is inheritance, but no luck this time: String class is sealed. :)

Of course there are ways, evil, but you have to ask the devil. :-D

check out extension methods

betonglasermur.FeedDwarf(pur_is, 17);
ProcessStartupInfo.AintNotCreateNoWindow = (false && !true) != (true || false) ? false == true ? true : false : (true != false && false);

there is a way, using extension methods. but this requires c# 3.0 .. Extension methods are static methods that can be invoked using instance method syntax. In effect, extension methods make it possible to extend existing types and constructed types with additional methods.

VICTORY!!!

using System;

class String
{
    public string RemoveFirst(string num)
    {
        //num = num.Remove(num);
        string toReturn = num.Remove(0, 1);
        return toReturn;
        //Console.WriteLine("Hackz0red!");
    }
}

class ExtMethodDemo
{
    static void Main(string\[\] args)
    {
        String r1 = new String();
        string r2 = r1.RemoveFirst("12345");
        Console.WriteLine(r2);
        Console.ReadLine();
    }
}

Thanks laserbaronen!!! :D

hmm o_o

public static class ExtMethods
{
public static string RemoveFirst(this string str)
{
return str.Remove(0,1);
}
}
class ExtMethodDemo
{
static void Main(string[] args)
{
string r1 = "12345".RemoveFirst();
Console.WriteLine(r1);
Console.ReadLine();
}
}

was thinking something like this

make it appear possible, when in fact it isn't. :-D

that's just what c# 3.0 specification says.
