Question

Let say I have this example:

class A : SomeAbstractClassWithProperties
{
  public A(string id, int size)
  {
    this.Name = "Name1";
    this.Something = new SomethingElse(id, size);
  }

  //...some stuff
}

class B : A
{
  public B(string id, int size)
  {
    this.Name = "Name2";
    this.Something = new SomethingElse(id, size);
  }
}

Ok this is not gonna work:

Inconsistent accessibility: base class A is less accessible than class 'B'
'A' does not contain a constructor that takes 0 arguments

But as we see the constructor of Class A and Class B are almost the same. Just this.Name is different. How could I rewrite class B? Any suggestions? Thank you

Please update your code

class B : A
{
  public class B(string id, int size) : base(id, size) 
  { 
     this.Name = "Name2";
  }
}

The case is you B constructor tries to call A() default constructor which desn’t exists.
