Can we have the body for the default constructor in C # at run time?

Question

There will be a constructor in the class. If the programmer determines that then definitely he will have a body. But if we do not define it, will this constructor have a default body in it?

Answer 1

If you leave the default constructor implementation to the compiler (what happens if you do not define it), the constructor will initialize all the default fields For example.

class With<T>
{
  T field;
  string str;
  With()
  {
    field = default(T);
    str = "";
  }
}

class WithOut<T>
{
  T field;
  string str = "";
}

from the functional point of view will have the same default constructor

Answer 2

If you have the following class:

class A { }

, . , :

class A 
{ 
    private string someField = "some text";
}

... .

Answer 6

, , object. ...

public object()
{
}

, :

public sealed class Person
{
    public string Name = string.Empty;
    public string Firstname = string.Empty;
    public string Middlename = string.Empty;

    public string Fullname
    {
        get { return string.Concat(Name, Firstname, Middlename); }
    }

}

:

public Person()
{
    this.Name = string.Empty;
    this.Firstname = string.Empty;
    this.Middlename = string.Empty;
}

EDIT: if you use the .NET Reflector, you can parse the assemblies to see what is really happening.
