Calling a constructor from another constructor

Question

I want to do something like this

public class Class1
    {
       public Class1()
       {

       }
       public Class1(int a)
       {

       }
    }
   public class Class2 :Class1
    {
       public Class2(int a)
       {

       }
       public Class2(): base(2)
       {
         this(2);   // new Class2(2);
       }

    }

I know this cannot be achieved in Java (you can use one of (super or this) in the first line)

But for some reason I need such work, how to do it? A tool that calls the constructor with the parameterized and derived classes of the base class in the default constructor of the derived class.

Answer 1

The MSDN article on designers is pretty good. Here are a few relevant bits:

base .
....
, . , , , .

:

public class Class1
{
   public Class1()
   {

   }
   public Class1(int a)
   {

   }
}
public class Class2 :Class1
{
   public Class2(int a) : base(a)
   {

   }
   public Class2(): this(2)
   {
   }

}
