Question

目标：从系统中获取所有登录/注销的用户。通过远程桌面连接登录/注销的用户。

我的剧本：

Param(
    [array]$ServersToQuery = (hostname),
    [datetime]$StartTime = "January 1, 1970"
)

    foreach ($Server in $ServersToQuery) {

        $LogFilter = @{
            LogName = 'Microsoft-Windows-TerminalServices-LocalSessionManager/Operational'
            ID = 21, 23, 24, 25
            StartTime = $StartTime
            }

        $AllEntries = Get-WinEvent -FilterHashtable $LogFilter -ComputerName $Server

        $AllEntries | Foreach { 
            $entry = [xml]$_.ToXml()
            [array]$Output += New-Object PSObject -Property @{
                TimeCreated = $_.TimeCreated
                User = $entry.Event.UserData.EventXML.User
                IPAddress = $entry.Event.UserData.EventXML.Address
                EventID = $entry.Event.System.EventID
                ServerName = $Server
                }        
            } 

    }

    $FilteredOutput += $Output | Select TimeCreated, User, ServerName, IPAddress, @{Name='Action';Expression={
                if ($_.EventID -eq '21'){"logon"}
                if ($_.EventID -eq '22'){"Shell start"}
                if ($_.EventID -eq '23'){"logoff"}
                if ($_.EventID -eq '24'){"disconnected"}
                if ($_.EventID -eq '25'){"reconnection"}
                }
            }

    $Date = (Get-Date -Format s) -replace ":", "."
    $FilePath = "$env:USERPROFILE\Desktop\$Date`_RDP_Report.csv"
    $FilteredOutput | Sort TimeCreated | Export-Csv $FilePath -NoTypeInformation

Write-host "Writing File: $FilePath" -ForegroundColor Cyan
Write-host "Done!" -ForegroundColor Cyan

我真的不懂ps1脚本。我找到了这个脚本，但我想将它用于我的目的。

当我尝试用c＃执行它时：

情景1：

string scriptText = "C:\\MyPath\\script.ps1";
            try
            {
                Runspace runspace = RunspaceFactory.CreateRunspace();

                // open it

                runspace.Open();

                // create a pipeline and feed it the script text

                Pipeline pipeline = runspace.CreatePipeline();
                pipeline.Commands.AddScript(scriptText);
  Collection<PSObject> results = pipeline.Invoke();

它会抛出错误：

ps1未经过数字签名。

第二种情况：

using (PowerShell PowerShellInstance = PowerShell.Create())
            {
                PowerShellInstance.AddScript(str_Path);
                Collection<PSObject> PSOutput = PowerShellInstance.Invoke();

                if (PowerShellInstance.Streams.Error.Count > 0)
                {
                    // error records were written to the error stream.
                    // do something with the items found.
                }
              }

Streams总是空的。实际上它总是计算0行。

有任何想法/建议如何完成这项工作？

Answer 1

我在脚本末尾使用Write-Output而不是Write-Host而不生成csv文件。致this。

运行并处理ps1脚本的输出
