Can I call an overloaded constructor from another constructor of the same class in C

Question

User · Answer

If you mean if you can do ctor chaining in C#, the answer is yes. The question has already been asked.

However it seems from the comments, it seems what you really intend to ask is 'Can I call an overloaded constructor from within another constructor with pre/post processing?'
Although C# doesn't have the syntax to do this, you could do this with a common initialization function (like you would do in C++ which doesn't support ctor chaining)

class A
{
  //ctor chaining
  public A() : this(0)
  {  
      Console.WriteLine("default ctor"); 
  }

  public A(int i)
  {  
      Init(i); 
  }

  // what you want
  public A(string s)
  {  
      Console.WriteLine("string ctor overload" );
      Console.WriteLine("pre-processing" );
      Init(Int32.Parse(s));
      Console.WriteLine("post-processing" );
  }

   private void Init(int i)
   {
      Console.WriteLine("int ctor {0}", i);
   }
}

In C  it is not possible to call another constructor from inside the method body  You can call a base constructor this way  foo args  base   as pointed out yourself  You can also call another constructor in the same class  foo args  this     When you want to do something before calling a base constructor  it seems the construction of the base is class is dependant of some external things  If so  you should through arguments of the base constructor  not by setting properties of the base class or something like that

No  You can t do that  the only place you can call the constructor from another constructor in C  is immediately after     after the constructor  for example  class foo       public foo         public foo string s           public foo  string s1  string s2    this s1
