What is base. ctor (); In C #?

I am disassembling some C # applications and I am trying to reconstruct the source code. I am disassembling the application along with the required DLLs.
I keep coming across this line base..ctor(); which gives me an error. The line occurs in some voids with in some subclasses of Stream and Exception .

Does anyone has any idea what the code should is? I am thinking the disassembler messed it up some what and it is clearly invalid code. So does anyone know what's it is meant to mean and how can I change the line so it works?

Here is the code of the one of the subclasses. Occurs in:

 [Guid (    ]  public  class   zlibexception:exception{ public   Zlibexception () { base  .        ctor ();     return  ;  public  zlibexception (string  Span style= "color: #000000;" > s) { base  .        ctor ();     return  ; }}

It should be:

[Guid ("ebc25cf6-9120-4283-b972-0e5520d0000e")]  Public class zlibexception:exception{    publicbase()    {        return ;    }      Public Zlibexception (stringbase()    {        return;    }}

Which calls the constructor with that signature on the base implementation of this class.

But by default the. NET CLR calls the base, blank constructor for your, so you don ' t actually need the: base()
