目前，我正在尝试使用WinSCP API将文件上传到服务器。
但是，每次尝试执行此操作时查看日志文件，都会收到错误消息，指出远程文件或其目录不存在。
代码：
Dim objftp As New WinSCP.SessionOptions
objftp.HostName = Server
objftp.PortNumber = Port
objftp.Protocol = Protocol.Sftp
objftp.UserName = User
objftp.Password = Password
objftp.PrivateKeyPassphrase = "passPhrase"
objftp.SshPrivateKeyPath = "\\PathToPrivatekey.ppk"
objftp.GiveUpSecurityAndAcceptAnySshHostKey = True
Dim session As New Session
session.Timeout = System.TimeSpan.FromSeconds(30)
session.SessionLogPath = "C:\Temp\ftpLog\winscp.log"
session.Open(objFTP)
Dim transferOptions As New TransferOptions
transferOptions.TransferMode = TransferMode.Binary
transferOptions.ResumeSupport.State = TransferResumeSupportState.Off
Dim transferResult As TransferOperationResult
strLocalFile = FilePath & FileName
strRemoteFile = FileName
transferResult = session.PutFiles(strLocalFile, "/In/", False, transferOptions)
transferResult.Check()
session.Close()
现在我手动使用连接到服务器的WinSCP，我可以验证/In/目录是否存在。我正在使用Windows操作系统来执行此操作。我没有关于我连接的服务器的完整详细信息，因为它是我发送信息的第三方。
我的代码中是否缺少某些内容？
编辑：根据要求，这是我的日志：

答案 0 :(得分：2)
虽然我无法确定，但由于您没有提供足够的信息，我的猜测是您的真实目标路径应该是/Home/user/In/，而不仅仅是/In/。
从GUI日志中，您的帐户似乎没有被提交，因为主目录是/Home/user/，而不是/。
. 2016-12-23 10:59:14.386 Listing directory "/Home/user".
答案 1 :(得分：0)
Documentation讨论了远程文件的完整路径，而不是文件目录。您可以尝试指定完整路径：
transferResult = session.PutFiles(strLocalFile, "/In/remote_file.ext", False, transferOptions)
