you can use Extension Methods
For example
static class MyExtensions
{
public static void showInfo(this User user)
{
Console.WriteLine("Name :{0}\nAge :{1}",user.Name,user.Age);
}
public ststic void TellType(this string str)
{
Console.WriteLine("I am string:{0}",str);
}
}

public staic void main()
{
User user=new User{Name="Emma" ,Age=26};
//use the extension methods
user.showInfo();
string str="123abc";
str.TellType();
}
}
