Looking for a compression library that gets around? LZO is a fast compression library that was actually uses on the NASA rovers Spirit and Opportunity. Michael Link created a .NET wrapper class so using it is a breeze. The following is the sample application listed on the LZO.NET home page:
// Create the compressor object
LZOCompressor lzo = newLZOCompressor();
// Build a quite redundant string
StringBuilder sb = newStringBuilder();
for (int i = 0; i < 10000; i++)
{
sb.Append("LZO.NET");
}
string str = sb.ToString();
Console.WriteLine("Original-Length: " + str.Length);
// Now compress the 70000 byte string to something much smaller
byte[] compressed = lzo.Compress(Encoding.Default.GetBytes(str));
Console.WriteLine("Compressed-Length: " + compressed.Length);
// Decompress the string to its original content
string str2 = Encoding.Default.GetString(lzo.Decompress(compressed));
Console.WriteLine("Decompressed-Length: " + str2.Length);
Console.WriteLine("Equality: " + str.Equals(str2));
Even though no mention is made of .NET 2.0 it still works just as advertised.
