Convert Python to C# help.

[toanmh]

I have code to unwrap package. But i don'nt know python language. Please help me to convert this code to C# or Java. Thanks for help.!

Just call this code from you Java/C is surely the easiest way?

Just call this code from you Java/C is surely the easiest way?

I tried calling from C # but can not be executed due to lack some Base64 and zlib libraries. If rewritten in languages other languages (C #, Java) will be more easily modified for applications.

You might get more help on the C# or Java forums? But installing new packages for python shouldn't be very difficult.

I wrote a Python-based application framework. Net. IDE is sharpdeverlop3. 0 (enclosed in the path) you could help me fix it?.

I don't think I have the knowledge. Sorry.

hello, I have almost, use IronPython, the only problem I have I can not import the zlib library, did you resolve this in any way?

[cr4sh]

call the function using JSL. might be of some help.

JSL = Java Script library??
how?
