WinSCP C#首次使用

我在电脑上安装了WinSCP，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，提示：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。。我试着做了一次尝试..抓住了我的全部代码，但它也没有抓住错误

出现错误（来自web的图片，而不是我的应用程序的屏幕截图）：

尝试类似的方法（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\u安装“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已安装/解压缩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。“尝试将.exe放入应用程序文件夹中

要将winSCP dll合并到exe中，请读取

请发布有关崩溃的所有相关信息，特别是确切的错误消息。如果可用，回溯也会很有用。崩溃的原因是什么？检查计算机的事件日志，或者在Visual Studio中运行它，看看它说了些什么。这当然对我们来说非常重要，因为我们能够帮助您找出问题所在sue是。弹出一个警告，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。可能是因为在我的本地pc上，我的visual studio带有.dll，但应用程序运行在服务器上？因此，为了澄清：我在服务器上安装了WINSCP，它位于上面的路径中。您需要告诉我们实际异常是为了让我们能够帮助您。并检查Windows日志下的应用程序日志。它可能会列出应用程序异常消息和详细信息。通过更新您的问题向我们提供这些信息。发布调用WinSCP的随机代码如何回答此问题（关于崩溃）？@FrédéricHamidi首先，这不是随机的，我的笨家伙，这是一个工作代码的例子。其次，我从未见过它像OP那样被调用，你像我一样做，就像他们的文档描述的那样，除非你当然是从命令行运行它，而他们不是。我想我的问题是我安装的winscp不正确..但是不要知道W如何正确地安装它。因为你的答案与解决方案无关，所以我否决了。评论在回答时并不重要，因为评论被认为是短暂的，而且如果你反而显示了如何检索异常细节，很多评论是可以避免的。对话已结束。WinScp可以打开1个会话并继续，或者需要打开新会话，就像按按钮一样。文件上载/下载我不确定，我每次都创建了新会话以上载/下载
