Question

我在我的PC上安装了WinSCP，并希望通过C＃控制台应用程序连接到另一台服务器。

 using WinSCP;
namespace WINSCP_SFTP
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                Console.WriteLine("test");
                SessionOptions sessionOptions = new SessionOptions
                {
                   Protocol = Protocol.Sftp,
                   HostName = "hostname",
                   UserName = "user",
                   Password = "password"
                 };

                 using (Session session = new Session())
                 {
                    session.ExecutablePath = @"C:\Program Files\WinSCP";
                    session.Open(sessionOptions);

                    Console.WriteLine(session.Opened);
                 }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

            Console.ReadLine();
        }
    }
}

但是如果我运行.exe，应用程序甚至会在第一个console.writeline出现之前崩溃..任何想法我做错了什么？

更新：弹出一个警告说：WINSCP_SFTP已停止工作..然后在cmd行中出现一个文本：Unhandled Exception ..我试图围绕我的整个代码进行try..catch，但它也没有捕获错误

发生错误（来自网络的图片，而非我的应用程序的屏幕截图）： enter image description here

Answer 1

尝试更像这样的东西（这来自Windows Web服务）。

winscp.exe必须位于应用程序的根目录中。

编辑：请参阅winscp.net/eng/docs/library_install" WinSCP .NET程序集与WinSCP winscp.exe交互。默认情况下，它会在存储程序集的同一文件夹中查找winscp.exe。因此，您应该将包解压缩到安装/提取WinSCP的同一文件夹中。您还可以将所有二进制文件winscp.exe和winscpnet.dll复制到单独的文件夹中。＆＃34;尝试将.exe放在您的app文件夹中。

要将winSCP dll合并到您的exe中，请阅读Embedding DLLs in a compiled executable

        Protocol = Protocol.Sftp,

        UserName = EdiConfiguration.FtpUserName,
        Password = EdiConfiguration.FtpPassword,
        SshHostKeyFingerprint = EdiConfiguration.SshHostKeyFingerprint,
        PortNumber = EdiConfiguration.FtpPortNumber
    };

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

        TransferOptions transferOptions = new TransferOptions();
        transferOptions.TransferMode = TransferMode.Binary;
        transferOptions.ResumeSupport.State = TransferResumeSupportState.Off;

        // Download the files in the OUT directory.
        TransferOperationResult transferOperationResult = session.GetFiles(EdiConfiguration.FtpDirectory, EdiConfiguration.IncommingFilePath, false, transferOptions);

        // Check and throw if there are any errors with the transfer operation.
        transferOperationResult.Check();

        // Remove files that have been downloaded.
        foreach (TransferEventArgs transfer in transferOperationResult.Transfers)
