.Net dll from Java

Hi,

I found numerous links about how C++ / Win32 dll s can be called from Java. Some useful links are given below.

http://sourceforge.net/projects/jawinproject/
https://www.experts-exchange.com/questions/23025774/Java-and-DLLs.html?sfQueryTermInfo=1+10+30+dll+java

etc. etc.

Now my question is can I use .Net dlls from java? If it is possible then how it is possible? I repeat, I am not asking about COM dll, but asking about .Net dlls. Which may be heavily dependent on Framework.

Is it possible? I have not any fair idea about CORBA / JNI. Is this possible in those?

Yes, those r nice links which is telling that .Net dlls can be used from Java by JNI. Thanx for that. I really appreciate for those links.

But is there any sample code which demonstrates how to use C# 2008 dll from Java? I am not finding any links, all those are available which are demonstration of how to call C/C++ dlls from java. Please help

is it? there is no diffrence between C/C++ dll and those dlls generated in C# by "Class Library" type project selection? If I add following two lines in that C# dll

using system.windows.forms;

public void SayHello()
{
MessageBox.Show("Hello", "Test", MessageBoxButton.OK, MessageBoxIcon.Information);
}

compile that in dll, and try to call it from Java, should it work?

Thanx

OK, searching in net I have found a usefull (for me atleast) link at the following:

http://www.codeproject.com/KB/java/DebugJavaJNIApplication.aspx

Now as I proceed believing C# dll will work with JNI same as the C++ do, I have stuck out in the following codes of the above link !

#include "NativeAdd.h"

jdouble JNICALL Java_nativegui_NativeAdd_add
(JNIEnv *env, jclass cls, jdouble n1, jdouble n2)
{
return n1 + n2;
}

No place to write those lines in C# !! Please help, how this can be done in C#?

Thanx
