An explanation about base..ctor()

Question

I'm getting an application from my friends to develop. Then in the code I got confusing code like this:

public someNameHere()
{
   base..ctor();
} 

Well I've never had an application like this. I need an explanation for this

base..ctor();

I've googling and can't find answer that satisfy me. I appreciate for any help you give me.

Answer 1

.ctor() is the internal name used by constructors. It is not used that way in C#, and does not compile. More typically, base..ctor() is only used by the compiler when doing things like:

public class Foo : Bar {
    public Foo(string s) : base(s) {...} 
    public Foo() {...} // has an implicit :base()
}

The only times I've seen that done differently is when decompiling (via reflector etc) some non-C# IL that does the construction code in a different sequence to how the C# compiler does it, which is therefore not expressable in "pure" C#. In raw IL (and from C++ etc) you can call the base-constructor at any point in the constructor - not just at the start.

Answer 2

Should be the default parameterless constructor of your base class. Elaborating, .ctor() is the alias for constructor automatically generated compiling C#. So Writing base..ctor() is referencing the .ctor() method in the base class.
