WinSCP C# 初次使用

Question

我在我的 PC 上安装了 WinSCP，想通过 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，应用程序甚至在第一个 console.writeline 出现之前就崩溃了。知道我做错了什么吗？

更新：弹出一个警报，上面写着：WINSCP_SFTP 已停止工作.. 然后在 cmd 行中出现一个文本：未处理的异常.. 我尝试尝试 try..catch 我的整个代码但它也没有捕获错误

出现错误（图片来自网络，不是我的应用截图）：

Answer 1

尝试更多类似的东西（这来自 windows 网络服务）。

winscp.exe 必须在应用程序的根目录中。

编辑：查看 winscp。net/eng/docs/library_install "WinSCP .NET assembly interacts with WinSCP winscp.exe. By default it looks for the winscp.exe in the same folder, where the assembly is stored. For that reason, you should extract the package into the same folder, where you have WinSCP installed/extracted. You can also copy all binaries, winscp.exe and winscpnet.dll, into separate folder. " 尝试将 .exe 放入您的应用程序文件夹。

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

using WinSCP;

        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)
