I have 2 files writen in java, if someone can please covert them in C# and give it.

The problem is with type of variables and operators, many operators are not overloaded like in java, idk what to say...

This one will not work in C# as integer

result |= _decrypt[_off++] << 0x18 & 0xff000000;

i change it to long, but i get "Warnings" in smallers

Also, here get error with << operator

result |= (_decrypt[_off++] & 0xffl) << 8l;

Um I thought writing code for someone isn't allowd here....

Writing the code for someone is not the problem.
Doing someone's homework with no effort from them is a problem.

... im newbie in C#, ...

I'm glad you're trying to do this.
It would be much better for you to figure out this one by yourself as it will teach you more than you could learn from someone else writing it.

The upper code is just conversion from java, http://svn.l2jserver.com/trunk/L2J_Server/java/com/l2jserver/util/network/

Im trying to convert everything in C# in my free time, you will say me " why you do that, C# is same sh1t with java.."

I do it just to learn from it, i want to learn work with bytes/sockets/threads/fileIO...
this project i think is good deal for me, if i done it in about 4-5 Month i will be glad :D

looks like a private server of mmo to me am i right?
