.NET FW4.6.2.NET FW4.7.NET FW4.7.1.NET FW4.7.2
A NuGet package for C# that wraps libzstd.dll for compression and decompression using Zstandard.
Get Started
$ dotnet add package Zstd.NetFrameworkReadme
Zstd.NetFramework
This is a Wrappers based on P/Invoke implementations.
Functions implemented by calling facebook/zstd(dev).

Demo
using CN.Lalaki.Zstd;
using System.IO;
using System;
// ...sample code
using (var cstream = File.OpenRead("path\\of\\example.zst"))
{
MemoryStream destream = new MemoryStream();
// Decompress Stream
Zstd.DecompressStream(cstream, destream);
var c2stream = new MemoryStream();
destream.Seek(0, SeekOrigin.Begin);
// Compress Stream
Zstd.CompressStream(destream, c2stream, 3);
// Decompress Byte Array
const int bufferSize = 1024 * 1024 * 20; // if 20MB, must be larger than original file size
var ddata = Zstd.Decompress(c2stream.ToArray(), bufferSize);
Console.WriteLine("Decompress Size: {0}", ddata.Length);
// Compress Byte Array
var cdata = Zstd.Compress(ddata, 3);
Console.WriteLine("Compress Size {0}", cdata.Length);
