Hi everyone!

Every class will have a constructor.If programmer defines that contructor then it will have a body.

But for default constructor which was not defined by a programmer can it have a body?

hi laxmi_hemu,

I am not sure I fully understand the question, but in C# if you don't define a default constructor a default constructor will be implicitly defined for you in the class. It initialises the member variables to their default values.

So even if you have a class without a constructor defined, you can still fo something like

MyClass myClass = new MyClass();

This link from MSDN should give you more insight. MSDN: Constructors[^]

Hope this helps :)

"in C# if you don't define a default constructor a default constructor will be implicitly defined for you in the class" - This is valid only for non-static classes. :)

The constructor which takes no argument is called default constructor.And it wil contains some coding part in it, which depends on the requirement of the application.

Even generated from compiler the default constructor has a body.
Here is an example for a default constructor generated by the compiler (I've used ildasm[^] to get the IL code):

MSIL

.method public hidebysig specialname rtspecialname instance void .ctor() cil managed
{
    .maxstack 8
    L_0000: ldarg.0
    L_0001: call instance void [mscorlib]System.Object::.ctor()
    L_0006: ret
}

From the IL code above you can easily spot the call to the default constructor of the base class (in our case System.Object).
Additionally if your class is static no constructors will be generated.
