# Zstd.NetFramework

[![Available on NuGet https://www.nuget.org/packages?q=Zstd.NetFramework](https://img.shields.io/nuget/v/Zstd.NetFramework.svg?style=flat-square)](https://www.nuget.org/packages?q=Zstd.NetFramework)

This is a Wrappers based on P/Invoke implementations.

Functions implemented by calling [facebook/zstd](https://github.com/facebook/zstd)(dev).

## API

```cs

Zstd.Compress(byte[] src, int level)

Zstd.Decompress(byte[] src, int dstCapacity)

Zstd.CompressStream(Stream src, Stream dst, int level)

Zstd.DecompressStream(Stream src, Stream dst)

Zstd.CompressStream2SimpleArgs(Stream src, Stream dst, int level)

Zstd.DecompressStreamSimpleArgs(Stream src, Stream dst)

```

## Demo

```cs

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);

}

```
