.net - 使用 WinSCP .NET 的方法未找到异常 (EventWaitHandle..ctor)

Question

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

代码无法打开 session ( $session.Open($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，它是从 $session.Open($sessionOptions) 跳转的至 $session.Dispose()并跳过代码的其他部分。

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
}

您很可能正在使用 PowerShell 6 或更新版本(又名 PowerShell Core)。这些版本的 PowerShell 使用 .NET (Core)，而不是 .NET Framework。
因此，您必须使用 WinSCP .NET 程序集的 .NET Standard 版本。内 WinSCP-*-Automation.zip package ，查看 netstandard2.0文件夹。
