The Java Set Interface is not strongly-typed either. In fact, it can contain
any combination of data in it, not just one type. See
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Set.html. I saw quite a
number of other C# Set Class implementations (see
http://www.google.com/search?hl=en&q=C%23+Set+Class), but the one that I
pointed you to was the closest one to the Java Set Interface, which I
thought was what you were looking for.

In any case, you are free to create your own Collection classes, derive from
any existing Collection class, and implement whatever functionality you
desire. Perhaps, considering your desire for strong typing, you might want
to start from one of the System.Collections.ObjectModel
(http://msdn2.microsoft.com/en-us/library/system.collections.objectmodel.aspx)
or System.Collections.Generic
(http://msdn2.microsoft.com/en-us/library/system.collections.generic.aspx)
namespace classes.

Dear all,

I'm familiar with the Set Class in C++ and Java; however, i have
been
searching in C# for a similar container as in c++ or collection as
in
java, but couldn't find one.
Could some one tell me about the the Set implementation inside .NET?

Best regards


I believe the Set.cs link http://www.devhood.com/tools/myDownload is
broken


My bad, my mozilla firefox prevented the scripts for the page, so i
couldn't download it! :-)

That is not true at all,

Since JDK 1.5 Update 2, Java came up with alot of stong typed generics
including the vector , set, ...etc. classes.
Earlier you could not for instance use a statement in Java like this:
java.util.Vector <SomeClass> v; It took every thing as object and u
needed to cast. However, as from Update 2 i guess of 1.5 jdk, they
adapted the STL implementation of strong typing.
