C# to JAVA converter? - C# / C Sharp

asj

just read about a person who did work in C# then decided to switch to
java (because he wanted to run his apps in multiple platforms, inc
linux). he mentioned that someone should market a c# to Java converter.

is there any such thing today?

there is almost surely no market for it right now (since there are not
that many mature c# projects around yet), but it might be something to
look at in the medium term future when movements from c# to java
accelerate.

This would be a tall order. The Java base classes are totally different
than the .NET ones in terms of heirarchy and use.
is there any such thing today?

If there is, it most likely produces poor code. Converting Java to C# using
an automated tool, for the reasons noted above, would most likely lead to a
bloated mess. Converting by hand by a skilled coder (i.e. knows both Java
and C# well) is probably currently the best method for conversion. Such a
tool might be viable after a few generations of releases, but I doubt it
could rival hand conversion.

Just my $.02...

Did you try it? I wonder if it can handle unsafe code.

There's a MSIL to Java source code convertor:

``The language module takes the .Net application's IL (intermediate
language) code and converts it to the Java source code. This module can
be run as a plug-in for Visual Studio.NET, or as a command line
executable. The runtime module replicates the functionality provided by
the .NET class libraries. All the libraries that come with .NET
(including classes such as ADO.NET, XML, SOAP) have been developed
using the Java language.''

Unsafe code really ought to be turned into C (JNI), but that's
somewhat more complicated. :)

LOL! their license even notes that they could radically change the thing
AT ANY TIME if microsoft suddenly PULLS THE RUG from under them with its
patents on .net....what idiot would base their work on a foundation as
legally creaky as that?

microsoft's cash cow is windows and ms office - it would make absolutely
no sense for them to give their developers the freedom to use linux, and
you can bet they'll jerk the noose when the time comes and (1) they
realize most developers aren't going to be fooled by mono; (2) mono
starts cutting into their bottom line - selling new windows server
licenses.

microsoft's relationship with open source is frigid at best....

on the other hand, Java is dominated nowadays by links to open
source...there are literally TONS of open source java implementations
(including tools like IDEs, APIs, libraries, etc), and apache (the open
source organization behind the dominant web server, apache) just
announced it would create the world's second open source j2ee
application server (after JBOSS).

there are even pressures to open source the ENTIRE standard j2se!

not that java and open source always stand eye to eye.

i happened upon this really HILARIOUS javablog about yesterday's
decision by apache to create a new open source j2ee app server (which
had previously had only 1 open source example, JBOSS).

the title, appropriately enough, is:

There are probably no such products on the market today. Most C#
projects I know of are either "evaluation " ones or are very recent in
terms of finalization. I will agree though that the market for such
might expand when C# projects are more prevalent. On the other hand,
the recent job postings seems to indicate the time when this happens
might be quite far off...the vast majority of .NET projects are
actually ASP.NET or VB.NET...perhap s someone should concentrate on
getting automated converters for these?

agreed. it will take a while (if ever) for c# to accumulate enough
market to even consider such a project, but it's getting there:
