Question

我正在尝试使用PowerShell和WinSCP .NET程序集连接到SFTP服务器。

代码无法打开会话（$session.Open($sessionOptions)）。

在我发现的日志中，

Exception: System.MissingMethodException: Method not found: 'Void System.Threading.EventWaitHandle..ctor(Boolean, System.Threading.EventResetMode, System.String, Boolean ByRef, System.Security.AccessControl.EventWaitHandleSecurity)'. at WinSCP.ExeSessionProcess.TryCreateEvent(String name, EventWaitHandle& ev) at WinSCP.ExeSessionProcess.InitializeConsole() at WinSCP.ExeSessionProcess.Start() at WinSCP.Session.Open(SessionOptions sessionOptions) [2019-03-14 10:59:02.835Z] [0013] Session.Cleanup entering [2019-03-14 10:59:02.835Z] [0013] Terminating process

基本上，它从$session.Open($sessionOptions)跳到$session.Dispose()，并跳过了代码的其他部分。

我试图在WinSCP论坛上找到解决方案，但没有帮助：

try {
    Add-Type -Path "M:\AMA\ztemp_powershell\WinSCPnet.dll" 

    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = "abc.xyz.ca"
        UserName = "abc_abc"
        Password = "*********"
        SshHostKeyFingerprint = "ssh-rsa 2048 **********************"
        PortNumber = 22
    }
    $session = New-Object WinSCP.Session   
    $session.ExecutablePath = "H:\FromLocal\Powershell\WinSCP.exe" 
    $filelist = Get-ChildItem M:\AMA\ztemp_powershell\sample_files

    try {
        # $session.DebugLogPath = "M:\AMA\ztemp_powershell\sftp1.log"
        $session.Open($sessionOptions)

        $transferOptions = New-Object WinSCP.TransferOptions
        $transferOptions.TransferMode = [WinSCP.TransferMode]::Binary

        foreach ($file in $filelist) {
            $transferResult =  $session.PutFiles("M:\AMA\ztemp_powershell\sample_files\$file" , "/outbox/", $false, $transferOptions)

            foreach ($transfer in $transferResult.Transfers) {
                Write-Host "Upload of $($transfer.FileName) succeeded"
            }
        }
    }
    finally {
        $session.Dispose()
    }
    exit 0
}
catch {
    Write-Host "Error: $_"
    exit 1
}

在论坛上，您写道您已经使用WinSCP .NET程序集5.13.8。

您已将查询发布到有关.NET Core 2.0和
缺少的方法是使用EventWaitHandleSecurity，它不是.NET Standard的一部分

基于上述事实，我认为您的项目针对的是.NET Standard，而WinSCP 5.13不支持。在WinSCP论坛上的答复中，我已经建议您升级到支持.NET Standard 2.0的WinSCP 5.14 RC。

使用WinSCP .NET找不到方法异常（EventWaitHandle..ctor）
