I've created a quick reference comparison of C# and
VB.NET that you might find useful. I couldn't find
anything like it on the web and so I made my own.

rison.html

It doesn't cover every area of the languages, just those
features most frequently used.

I also created a Java and C# comparison:

ison.html

I'd be thankful for any suggestions you may have on ways
to improve the comparisons.

Thanks,
Frank

You've fallen into the "objects are passed by reference" trap for Java
and C#. Please read
http://www.pobox.com/~skeet/csharp/parameters.html
I can't remember offhand whether or not Java is getting variable
parameter lengths in 1.5, but it may well be.

Picky things:

o Constants in Java are usually declared to be static. (It's implicit
in C#)

o Under enumerations, I believe the preferred order for modifiers is
"public static final int", although it doesn't matter too much. It
might also be worth mentioning that Java is getting enumerations in
1.5.

o Under arrays, in Java you can write:
int[][] x = new int[5][3];
but you can't do the same thing (with jagged arrays) in C#.

o Under foreach, it may be worth mentioning that Java is getting
foreach (in the form "for x : collection") in 1.5. The usual equivalent
of foreach would be done using an Iterator though.

o Under "choices", your code would give a warning under Java 1.4 (due
to the fallthrough).

o Under exception handling, not only is the argument itself entirely
optional in C#, but you can also get rid of *just* the variable name.
It would also be worth mentioning that C# (and .NET in general) doesn't
have checked exceptions.

o Under namespaces, your import statement is incorrect in Java - it
should either be "import Harding.Compsci.Graphics.*;" or
"import Harding.Compsci.Graphics.ClassName;". You might also want to
change the package name to "harding.compsci.graphics" to follow Java
conventions for the Java version.
 
Jon-

Thanks for your input. I will make some updates to the
Java/C# comparison soon.
