I was recently in a position where I needed to find a fast streamable compression solution. The great source by Markus Oberhumer provided the answer. After using the C code for a while, I realized C#/.NET lacked a similar library, short of one I found which was commercial.
As a result, I decided to attempt a minimalistic port of MiniLZO compression and decompression into pure C#. At this point, the code uses unsafe/fixed blocks to best mimic the original minilzo implementation. A pure managed solution may be soon to follow (at the cost of speed).
The code has not been unit tested 100%, but all initial tests have been successful. If anyone finds any bugs, please report them so I may fix it. I also have not done any profiling of the speed yet, if anyone feels upto the task of comparing it against the C implementation.
Use of the code is relatively simple, here is a quick example.
byte original = File.ReadAllBytes("...");
MiniLZO.Compress(original, out destination);
byte destination = ...;
byte original = new byte[x];
Note that with compression, the destination buffer will be assigned and trimmed to the correct size. With decompression, the "original" buffer must be preallocated with the correct original size. Also note that my implementation removed all use of
goto from the original source, and replaces certain uses with
