Can I call constructor from another constructor (as a regular method)?

Question

Let's say I have 2 constructors.

public class MyClass
{
   public MyClass()
   {
     int id = 0;
     //Same behaviour
   }
   Public MyClass(int id)
   {
     //Same behaviour
   }
}

Both constructions implement the same behavior. The only difference is that, if the first constructor is called and the value of id = 0;

My question is to know if I can call the second constructor, instead of implemetanting the same behavior? If that's possible, do I do it?

Answer 1

You can do this:

public class MyClass {
    public MyClass() : this(0) {
    }
    public MyClass(int id) {
    }
}

Here's Microsoft's documentation on it. (you have to scroll down a bit; try searching for : this)

Answer 2

public class MyClass
{
   public MyClass() : this(0)
   {
   }
   public MyClass(int id)
   {
     //Same behaviour
   }
}
