Hi,

I heard in some webinar that it was possible to initialize several
properties using only the default ctor provided the properties had public
getters/setters. Something like:

Instead of this:
Person p = new Person;
p.Name = "Juan";
p.LastName = "Dent";

This:

Person p =new Person( Name = "Juan", LastName = "Dent");

I know i saw it, but how is this possible?

Signature

Thanks in advance,

Juan Dent, M.Sc.

I think you're talking about object initialization:

Hi Juan,

As Alex mentioned, the properites initliazation syntax you mentioned is of
the C# 3.0 feature(in .NET 3.5):

#C# 3.0 Features: Object Initializers
