C# 使用WinSCP方法 類庫、腳本

官網下載：http://winscp.net/eng/docs/lang:chs

官網C#示例：http://winscp.net/eng/docs/library#csharp （全程英文，其他內容建議在園內搜索，其他地方好多沒有用的內容浪費時間）

引用類庫：WinSCPnet.dll

執行程序：WinSCP.exe  （放在項目根目錄中，沒有此文件類庫無法獨立運行）

難點： SshHostKeyFingerprint =  “ 給定的密鑰” 如果你不知道密鑰沒有關系，使用WinSCP.exe 程序，添加一個連接方式並登錄。 登錄后在Session選項中 選擇 Generate Session URL/Code .查詢軟件生成的代碼即可獲取 密鑰。

不同的版本密鑰也不一樣。

待解決問題：下載、上傳指定的文件類型 (如果有做完的同學請@我學習一下)

 

方式一 使用類庫操作

下載 PutFiles ， 上傳 PutFiles

        /// <summary>
        /// WinSCP數據傳輸
        /// </summary>
        /// <param name="winscptype">選擇操作方式：上傳、下載</param>
        /// <param name="srcPath">源目錄</param>
        /// <param name="objPath">目標目錄</param>
        /// <param name="hostName">IP地址</param>
        /// <param name="userName">賬戶</param>
        /// <param name="password">密碼</param>
        /// <returns></returns>
        public int WinSCP(WinSCPType winscptype, string srcPath, string objPath, string hostName, string userName, string password, int portNumber, string sshHostKeyFingerprint)
        {
            try
            {
             Setup session options
            SessionOptions sessionOptions = new SessionOptions
            {
                Protocol = Protocol.Sftp,
                HostName = hostName,
                UserName = userName,
                Password = password,
                PortNumber = portNumber,
                SshHostKeyFingerprint = sshHostKeyFingerprint,
                //SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...="
            };

            using (Session session = new Session())
            {
                // Connect
                session.Open(sessionOptions);

                // Upload files
                TransferOptions transferOptions = new TransferOptions();
                transferOptions.TransferMode = TransferMode.Binary;

                TransferOperationResult transferResult;
                switch (winscptype)
                {
                    case WinSCPType.Download:
                        transferResult = session.GetFiles(srcPath, objPath, false, transferOptions);
                        break;
                    case WinSCPType.Upload:
                        transferResult = session.PutFiles(srcPath, objPath, false, transferOptions);
                        break;
                    default:
                        transferResult = session.GetFiles(srcPath, objPath, false, transferOptions);
                        break;
                }

                // Throw on any error
                transferResult.Check();

                // Print results
                foreach (TransferEventArgs transfer in transferResult.Transfers)
                {
                    Console.WriteLine("{1} of {0} succeeded", transfer.FileName, Enum.Parse(typeof(WinSCPType), winscptype.GetHashCode().ToString()).ToString());
                }
            }

            return 0;
            }
            catch (Exception e)
            {
                Console.WriteLine("Error: {0}", e);
                return 1;
            }
        }

　操作枚舉

public enum WinSCPType
{
    Download = 0,
    Upload = 1

}

　

方法二  使用腳本執行操作

     private string winSCPDefaultPath = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase + "WinSCP.exe";

        public string GetWinSCPBackupScript(string name, string pass, string ip, string backup_src, string backup_obj)
        {
            if (!File.Exists(winSCPDefaultPath))
            {
                Console.WriteLine("WinSCP.exe 執行程序不存在. 無法執行");
                return "WinSCP.exe 執行程序不存在. 無法執行";
            }

            StringBuilder sb = new StringBuilder();
            sb.AppendFormat("{0} /console /command", winSCPDefaultPath);
            sb.Append(" \"option batch continue\"");
            sb.Append(" \"option echo on\"");
            sb.Append(" \"option transfer binary\"");
            sb.AppendFormat(" \"open {0}:{1}@{2}\"", name, pass, ip);
            sb.AppendFormat(" \"cd {0}\"", backup_src);
            sb.AppendFormat(" \"lcd {0}\"", backup_obj);
            sb.AppendFormat(" \"get *.dat\"");

            //sb.AppendFormat(" \"get {0}/{2}  {1}\\{2} \"", backup_src, backup_obj, GetWeek() - 1);
            sb.AppendFormat(" \"exit\"");
            return sb.ToString();

        }
