使用Session.PutFile函数时，检查文件是否在WinSCP中成功传输

using WinSCP;

class Program
{
    static void Main()
    {
        // 创建一个新的Session实例
        SessionOptions sessionOptions = new SessionOptions
        {
            Protocol = Protocol.Sftp,
            HostName = "example.com",
            UserName = "username",
            Password = "password",
            SshHostKeyFingerprint = "ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx"
        };

        using (Session session = new Session())
        {
            // 连接到远程服务器
            session.Open(sessionOptions);

            // 上传文件
            TransferOperationResult transferResult = session.PutFiles("C:\\local\\file.txt", "/remote/file.txt");

            // 检查传输结果
            if (transferResult.IsSuccess)
            {
                Console.WriteLine("文件传输成功");
            }
            else
            {
                Console.WriteLine("文件传输失败: " + transferResult.Failures[0].Message);
            }
        }
    }
}
