使用WinSCP .NET程序集时PreserveTimestamp属性找不到问题求助

错误原因 #

你直接在Session对象上设置PreserveTimestamp是错误的——该属性不属于Session类，而是**TransferOptions传输选项类**的属性。同时服务器不支持时间戳保留操作，需要在传输配置中关闭该功能。

正确设置方式及修改后的脚本 #

将PreserveTimestamp设置到TransferOptions实例中，并在调用PutFiles时传入该选项：

# 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 ...="
}

# 若需要忽略权限错误，可添加以下配置
# $sessionOptions.AddRawSettings("IgnorePermissionErrors", "1")

$session = New-Object WinSCP.Session

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

    # 创建传输选项并关闭时间戳保留
    $transferOptions = New-Object WinSCP.TransferOptions
    $transferOptions.PreserveTimestamp = $False

    # 上传时传入传输选项
    $session.PutFiles("filename.xlsx", "/destination/", $False, $transferOptions).Check()
}
finally
{
    # Disconnect, clean up
    $session.Dispose()
}

关键说明 #

• PutFiles方法的第四个参数为TransferOptions实例，必须正确传入才能让配置生效
• 若仍有权限相关错误，可在SessionOptions中添加$sessionOptions.AddRawSettings("IgnorePermissionErrors", "1")开启忽略权限错误选项
