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);
