本文会介绍几种访问共享目录的几种方式（Windows和Linux）
第一种是通过命令连接到共享目录后再进行读写操作，第二种通过WebClient的方式连接目录后进行读写；
第三种SSH的方式进行读写（.net core 的Linux环境下访问共享目录）
1、命令方式连接后读写
连接：
/// <summary>
/// 连接远程共享文件夹
/// </summary>
/// <param name="path">远程共享文件夹的路径</param>
/// <param name="userName">用户名</param>
/// <param name="passWord">密码</param>
/// <returns></returns>
public static bool connectState(string path, string userName, string passWord)
{
bool Flag = false;
Process proc = new Process();
try
{
proc.StartInfo.FileName = "cmd.exe";
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardInput = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.CreateNoWindow = true;
proc.Start();
string dosLine = "net use " + path + " " + passWord + " /user:" + userName;
proc.StandardInput.WriteLine(dosLine);
proc.StandardInput.WriteLine("exit");
while (!proc.HasExited)
{
proc.WaitForExit(1000);
}
string errormsg = proc.StandardError.ReadToEnd();
proc.StandardError.Close();
if (string.IsNullOrEmpty(errormsg))
{
Flag = true;
}
else
{
throw new Exception(errormsg);
}
}
catch (Exception ex)
{
throw ex;
}
finally
{
proc.Close();
proc.Dispose();
}
return Flag;
}
下载：
/// <summary>
/// 从远程服务器下载文件到本地
/// </summary>
/// <param name="src">下载到本地后的文件路径，包含文件的扩展名</param>
/// <param name="dst">远程服务器路径（共享文件夹路径）</param>
/// <param name="fileName">远程服务器（共享文件夹）中的文件名称，包含扩展名</param>
public static void TransportRemoteToLocal(string src, string dst, string fileName) //src：下载到本地后的文件路径 dst：远程服务器路径 fileName:远程服务器dst路径下的文件名
{
if (!Directory.Exists(dst))
{
Directory.CreateDirectory(dst);
}
dst = dst + fileName;
FileStream inFileStream = new FileStream(dst, FileMode.Open); //远程服务器文件 此处假定远程服务器共享文件夹下确实包含本文件，否则程序报错
FileStream outFileStream = new FileStream(src, FileMode.OpenOrCreate); //从远程服务器下载到本地的文件
byte[] buf = new byte[inFileStream.Length];
int byteCount;
while ((byteCount = inFileStream.Read(buf, 0, buf.Length)) > 0)
{
outFileStream.Write(buf, 0, byteCount);
}
inFileStream.Flush();
inFileStream.Close();
outFileStream.Flush();
outFileStream.Close();
}上传：
/// <summary>
/// 将本地文件上传到远程服务器共享目录
/// </summary>
/// <param name="src">本地文件的绝对路径，包含扩展名</param>
/// <param name="dst">远程服务器共享文件路径，不包含文件扩展名</param>
/// <param name="fileName">上传到远程服务器后的文件扩展名</param>
public static void TransportLocalToRemote(string src, string dst, string fileName) //src
{
FileStream inFileStream = new FileStream(src, FileMode.Open); //此处假定本地文件存在，不然程序会报错
if (!Directory.Exists(dst)) //判断上传到的远程服务器路径是否存在
{
Directory.CreateDirectory(dst);
}
dst = dst + fileName; //上传到远程服务器共享文件夹后文件的绝对路径
FileStream outFileStream = new FileStream(dst, FileMode.OpenOrCreate);
byte[] buf = new byte[inFileStream.Length];
int byteCount;
while ((byteCount = inFileStream.Read(buf, 0, buf.Length)) > 0)
{
outFileStream.Write(buf, 0, byteCount);
}
inFileStream.Flush();
inFileStream.Close();
outFileStream.Flush();
outFileStream.Close();
}使用：
bool status = false;
//连接
status = connectState(@"\\10.0.xx.xxx\ctec2", "waveaccess", "waveaccessxxx");
if (status)
{
//共享文件夹的目录
DirectoryInfo theFolder = new DirectoryInfo(@"\\10.0.xx.xxx\ctec2\");
string filename = theFolder.ToString();
//执行方法，方法一，读写时会有访问共享目录权限问题
TransportLocalToRemote(@"D:\readme1.txt", filename, "readme1.txt"); //实现将本地文件写入到远程服务器
TransportRemoteToLocal(@"D:\readme.txt", filename, "readme.txt"); //实现将远程服务器文件写入到本地
//执行方法，方法二，同一局域网时还有更简单的方式，连接后直接copy即可，且没有权限问题
File.Copy(@"D:\readme.txt", filename+"readme.txt", true);
}
else
{
Console.WriteLine("未能连接！");
}
Console.WriteLine("成功");2、WebClient的方式
上传：
/// <summary>
/// WebClient上传文件至服务器
/// </summary>
/// <param name="fileNamePath">文件名，全路径格式</param>
/// <param name="uriString">服务器文件夹路径</param>
/// <param name="IsAutoRename">是否自动按照时间重命名</param>
public static void UpLoadFile(string fileNamePath, string uriString)
{
string fileName = fileNamePath.Substring(fileNamePath.LastIndexOf("\\") + 1);
string NewFileName = fileName;
string fileNameExt = fileName.Substring(fileName.LastIndexOf(".") + 1);
if (uriString.EndsWith("/") == false) uriString = uriString + "/";
uriString = uriString + Path.GetFileName(fileNamePath);
/// 创建WebClient实例
System.Net.WebClient myWebClient = new WebClient();
myWebClient.Credentials = new NetworkCredential("user", "password");//指定用户名和密码
myWebClient.Credentials = CredentialCache.DefaultCredentials;
// 要上传的文件
FileStream fs = new FileStream(fileNamePath, FileMode.Open, FileAccess.Read);
BinaryReader r = new BinaryReader(fs);
byte[] postArray = r.ReadBytes((int)fs.Length);
Stream postStream = myWebClient.OpenWrite(uriString);//, "PUT"
try
{
//使用UploadFile方法可以用下面的格式
if (postStream.CanWrite)
{
postStream.Write(postArray, 0, postArray.Length);
postStream.Close();
fs.Dispose();
}
else
{
postStream.Close();
fs.Dispose();
}
}
catch (Exception err)
{
postStream.Close();
fs.Dispose();
throw err;
}
finally
{
postStream.Close();
fs.Dispose();
}
}下载：
//下载文件
public static void DownLoadFile(string URL, string DIR)
{
WebClient client = new WebClient();
string FileName = URL.Substring(URL.LastIndexOf("/") + 1);
string PATH = DIR + "\\"+FileName;
try
{
WebRequest SC = WebRequest.Create(URL);
client.DownloadFile(URL, PATH);
}
catch
{
}
}使用：
string uriString = "//192.168.1.40/shared/";
string fileNamePath = Environment.CurrentDirectory + "\\11111.zip";
UpLoadFile(fileNamePath, uriString);
DownLoadFile("//192.168.1.40/shared/11111.zip", Environment.CurrentDirectory);3、ssh的方式
使用了SSH.NET库，添加引用dll至项目
using Renci.SshNet; private static void SFTPtest()
{
try
{
string ip = "192.168.1.40";
//用户名和密码是访问该机器的用户名和密码
string user = "root";
string pass = "123456";
SftpClient sftp = new SftpClient(ip, user, pass);
sftp.Connect();
//上传
FileInfo fi = new FileInfo(Environment.CurrentDirectory + "\\111.txt");
var allLength = fi.Length;
sftp.UploadFile(new System.IO.FileStream(fi.FullName, System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.ReadWrite, System.IO.FileShare.ReadWrite), "/home/shared/黑龙江,哈尔滨市,阿城区县在线资源目录/采伐数据/采伐参考_20200722142705.zdb", (pro) => { Console.WriteLine((pro * 1.0d / allLength * 1.0d).ToString("P")); });
//下载
if (sftp.Exists("/home/shared/test/111.txt"))
{
using (var stream = File.Open(Environment.CurrentDirectory + "\\111.txt", FileMode.OpenOrCreate))
{
sftp.DownloadFile("/home/shared/test/111.txt", stream);
}
}
Console.WriteLine("finished.");
sftp.Disconnect();
}
catch (Exception ex)
{
}
}
