convert jar to apk using c # app

1.      Hello everyone,

I  want to make app in c # , That can convert jar to apk. please give me some idea about.

i don't have any idea about how i convert it.

Note:

  The porting tool searches for the jad/jar files located in the

   application folder structure i.e. it searches in Test\Bin and once found porting commences

  and the final apk file is created after porting. End Result should be Android_Version_Test.apk i.e.

  Android_1.6_Test.apk depending on the version of Android selected. If multiple versions of Android 

are selected then the tool should give out multiple versions and save them in the application folder i.e.

Test\Android\Version1.5, Version1.6, etc depending on the version or versions selected.

Please help me!
