dotnet compress Stream or file using lz4net

LZ4, a lossless compression algorithm, can be used in dotnet. The compression rate of this compression algorithm is not high but the speed is very fast.This library supports running on .NET Standard 1.6 .NET Core .NET Framework Mono Xamarin and UWP

The original code of the compression algorithm LZ4 is written in C, please see CodeK4os.Compression.LZ4 is written in C#, and there are also versions using C++ code

Because most of the time, Stream is compressed, so I will tell you how to compress Stream

Note that this compression algorithm is not zip or rar compression, that is, the compressed file cannot be opened with the current zip compression software, and the compressed content is not a file

Install using NuGetK4os.Compression.LZ4.Streams Simple to use LZ4 compression

If I need to compress a string to a file

using K4os.Compression.LZ4.Streams;using (var stream = LZ4Stream.Encode(File.Create("1.lz4"))){using (var sw = new StreamWriter(stream)){sw.WriteLine("Lin Dexi is funny");}}

Copy

This compresses the string into the file

Calling LZ4Stream.Encode to pass in stream and writing to the returned stream will be compressed to the incoming stream as above

The decompression is the LZ4Stream.Decode method, such as decompressing the above file

 using (var stream = new StreamReader(LZ4Stream.Decode(File.Open("1.lz4", FileMode.Open)))){Console.WriteLine(stream.ReadLine());}

Copy

Run the code and you can find that the output is funny. This is the simple use of LZ4, in fact, the complex use is similar to the simple one

Parameters can also be passed in Encode and Decode to configure higher performance compression
