SharpCifs.Std

Xamarin & .NET Core Ready, SMB/CIFS(Windows shared folder) Access Library.
This is a port of SharpCifs to .NET Standard.

Project Site:
http://sharpcifsstd.dobes.jp/

Xamarin/.NET Core対応のSMB/CIFS(Windows共有)アクセスライブラリです。
SharpCifsを .NET Standard に移植したものです。

Description

You can access the Windows shared folder, NAS by Xamarin, .NET Core.(= without mpr.dll, Netapi32.dll)
It's a rework of SharpCifs, and The origin is JCIFS.

Windowsの共有フォルダやNASへ、Xamarin/.NET Coreアプリからアクセス出来ます。
JCIFSのWindows Phone 8.1移植版だったSharpCifsを、.NET Standardで動作するように修正しました。

Supports .NET Standard 1.3 (= Xamarin.Android/iOS1.0, .NET Core1.0, .NET Framework 4.6)

Requirement

System.Console (>= 4.3.0)
System.Net.NameResolution (>= 4.3.0)
System.Net.NetworkInformation (>= 4.3.0)
System.Net.Sockets (>= 4.3.0)
System.Security.Cryptography.Algorithms (>= 4.3.0)
System.Security.Cryptography.Primitives (>= 4.3.0)
System.Threading.Tasks (>=4.3.0)
~~System.Threading.Thread (>= 4.3.0)~~ <-removed

Usage

Add NuGet Package to your project, or download this and add ref SharpCifs.STD1.3/SharpCifs.STD1.3.csproj
setting, ussage are same as JCIFS.

for installation details, Go to the Project Site - Installation. *

プロジェクトにNuGetパッケージを追加するか、
　もしくはこのソースをダウンロードの上 SharpCifs.STD1.3/SharpCifs.STD1.3.csproj をプロジェクト参照してください。
設定や使い方は、JCIFSに準じます。

インストール手順詳細は、プロジェクトページ - Installation を参照ください。 *

Get items in shared folder:

//using System;
//using SharpCifs.Smb;

//Get SmbFile-Object of a folder.
var folder = new SmbFile("smb://UserName:Password@ServerIP/ShareName/FolderName/");

//UnixTime
var epocDate = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);

//List items
foreach (SmbFile item in folder.ListFiles())
{
    var lastModDate = epocDate.AddMilliseconds(item.LastModified())
                              .ToLocalTime();

    var name = item.GetName();
    var type = item.IsDirectory() ? "dir" : "file";
    var date = lastModDate.ToString("yyyy-MM-dd HH:mm:ss");
    var msg = $"{name} ({type}) - LastMod: {date}";
    Console.WriteLine(msg);
}

Read a File:

//using System;
//using System.IO;
//using System.Text;
//using SharpCifs.Smb;

//Get target's SmbFile.
var file = new SmbFile("smb://UserName:Password@ServerIP/ShareName/Folder/FileName.txt");

//Get readable stream.
var readStream = file.GetInputStream();

//Create reading buffer.
var memStream = new MemoryStream();

//Get bytes.
((Stream)readStream).CopyTo(memStream);

//Dispose readable stream.
readStream.Dispose();

Console.WriteLine(Encoding.UTF8.GetString(memStream.ToArray()));

Create a new File:

//using System.Text;
//using SharpCifs.Smb;

//Get the SmbFile specifying the file name to be created.
var file = new SmbFile("smb://UserName:Password@ServerIP/ShareName/Folder/NewFileName.txt");

//Create file.
file.CreateNewFile();

//Get writable stream.
var writeStream = file.GetOutputStream();

//Write bytes.
writeStream.Write(Encoding.UTF8.GetBytes("Hello!"));

//Dispose writable stream.
writeStream.Dispose();

Scan Servers & Shares on LAN:

//using System;
//using SharpCifs.Smb;

//When using the host name when connecting,
//When using the host name when connecting,
//Change default local port(137) to a value larger than 1024.
//In many cases, use of the well-known port is restricted.
//
// ** If possible, using IP addresses instead of host names 
// ** to get better performance.
//
SharpCifs.Config.SetProperty("jcifs.smb.client.lport", "8137");

//Get local workgroups.
var lan = new SmbFile("smb://", "");
var workgroups = lan.ListFiles();

foreach (var workgroup in workgroups)
{
    Console.WriteLine($"Workgroup Name = {workgroup.GetName()}");

    try
    {
        //Get servers in workgroup.
        var servers = workgroup.ListFiles();
        foreach (var server in servers)
        {
            Console.WriteLine($"{workgroup.GetName()} - Server Name = {server.GetName()}");

            try
            {
                //Get shared folders in server.
                var shares = server.ListFiles();

                foreach (var share in shares)
                {
                    Console.WriteLine($"{workgroup.GetName()}{server.GetName()} - Share Name = {share.GetName()}");
                }
            }
            catch (Exception)
            {
                Console.WriteLine($"{workgroup.GetName()}{server.GetName()} - Access Denied");
            }
        }
    }
    catch (Exception)
    {
        Console.WriteLine($"{workgroup.GetName()} - Access Denied");
    }
}
