使用 WinSCP .NET 程序集时，无法在此对象上找到属性“PreserveTimestamp”

Question

我收到此错误：

The property 'PreserveTimestamp' cannot be found on this object. Verify that the property exists and can be set.
At path\OSBU_Broker_Extract02.ps1:14 
char:3
+   $session.PreserveTimestamp = $False
+   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : PropertyAssignmentException

If the problem persists, turn off setting permissions or preserving timestamp. Alternatively you can turn on 'Ignore 
permission errors' option.
The server does not support the operation.

我不确定应该在哪里设置变量，请参阅下面的代码：

# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"

# Setup session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = "[server IP]"
    UserName = "[username]"
    Password = ""
    SshHostKeyFingerprint = "ssh-rsa 1024 ...="
}

$session = New-Object WinSCP.Session
$session.PreserveTimestamp = $False

try
{
    # Connect
    $session.Open($sessionOptions)

    # Upload
    $session.PutFiles("filename.xlsx", "/destination/").Check()
}
finally
{
    # Disconnect, clean up
    $session.Dispose()
}

Answer 1

PreserveTimestamp

是

TransferOptions

类的属性，而不是

Session

。

A

TransferOptions

实例应作为

Session.PutFiles

:

的第四个参数传递

# Set up transfer options
$transferOptions = New-Object WinSCP.TransferOptions -Property @{
    PreserveTimestamp = $False
}

# Transfer files
$session.PutFiles("filename.xlsx", "/destination/", $False, $transferOptions).Check()

---

此外，一般来说，路径应该是绝对的（不仅仅是

filename.xlsx

）。
