将C#参数传递给Powershell脚本 - 无法验证参数'Identity'

标签: c# powershell parameters param

我正在尝试在C#中编写一个Windows窗体应用程序,为指定用户输出AD属性。我希望它工作的方式是用户在文本框中输入一个值(用户名),该文本框作为参数传递给Powershell脚本,输出显示在表单中。

用于创建参数和调用脚本的我的C#代码如下:

private string RunScript(string scriptText)
    {
        // create Powershell runspace 
        Runspace runspace = RunspaceFactory.CreateRunspace();

        // open it 
        runspace.Open();

        RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);

        // create a pipeline and feed it the script text 
        Pipeline pipeline = runspace.CreatePipeline();
        pipeline.Commands.AddScript(scriptText);
        pipeline.Commands.Add(new Command("Set-ExecutionPolicy Unrestricted -Scope Process", true));

        // "Get-Process" returns a collection of System.Diagnostics.Process instances. 
        pipeline.Commands.Add("Out-String");

        //Create parameter and pass value to script
        String username = textBox3.Text;
        String scriptfile = @"c:\\scripts\\getpasswordexpirydate.ps1";
        Command myCommand = new Command(scriptfile, false);
        CommandParameter testParam = new CommandParameter("username", username);
        myCommand.Parameters.Add(testParam);

        pipeline.Commands.Add(myCommand);
        // execute the script
        Collection<PSObject> results = pipeline.Invoke();

        // close the runspace 
        runspace.Close();

        // convert the script result into a single string 
        StringBuilder stringBuilder = new StringBuilder();
        foreach (PSObject obj in results)
        {
            stringBuilder.AppendLine(obj.ToString());
        }

        // return the results of the script that has 
        // now been converted to text 
        return stringBuilder.ToString();
    }

我的PowerShell脚本如下:

param([string]$username)

function Get-XADUserPasswordExpirationDate() {

Param ([Parameter(Mandatory=$true,  Position=0,  ValueFromPipeline=$true, HelpMessage="Identity of the Account")]

[Object] $accountIdentity)

PROCESS {

    $accountObj = Get-ADUser $accountIdentity -properties PasswordExpired, PasswordNeverExpires, PasswordLastSet

    if ($accountObj.PasswordExpired) {

        echo ("Password of account: " + $accountObj.Name + " already expired!")

    } else { 

        if ($accountObj.PasswordNeverExpires) {

            echo ("Password of account: " + $accountObj.Name + " is set to never expires!")

        } else {

            $passwordSetDate = $accountObj.PasswordLastSet

            if ($passwordSetDate -eq $null) {

                echo ("Password of account: " + $accountObj.Name + " has never been set!")

            }  else {

                $maxPasswordAgeTimeSpan = $null

                $dfl = (get-addomain).DomainMode

                if ($dfl -ge 3) { 

                    ## Greater than Windows2008 domain functional level

                    $accountFGPP = Get-ADUserResultantPasswordPolicy $accountObj

                    if ($accountFGPP -ne $null) {

                        $maxPasswordAgeTimeSpan = $accountFGPP.MaxPasswordAge

                    } else {

                        $maxPasswordAgeTimeSpan = (Get-ADDefaultDomainPasswordPolicy).MaxPasswordAge

                    }

                } else {

                    $maxPasswordAgeTimeSpan = (Get-ADDefaultDomainPasswordPolicy).MaxPasswordAge

                }

                if ($maxPasswordAgeTimeSpan -eq $null -or $maxPasswordAgeTimeSpan.TotalMilliseconds -eq 0) {

                    echo ("MaxPasswordAge is not set for the domain or is set to zero!")

                } else {

                    echo ("Password of account: " + $accountObj.Name + " expires on: " + ($passwordSetDate + $maxPasswordAgeTimeSpan))

                }

            }

        }

    }

}

}
Get-XADUserPasswordExpirationDate $username

Get-ADUser $username -Properties * | Select-Object DisplayName,LockedOut,LastLogonDate,kPMG-User-GOAccountType,kPMG-User-GOCompanyGroup,kPMG-User-GOFunction,kPMG-User-GOGrade,kPMG-User-GOManagementLevel,kPMG-User-GOMemberFirmGroup,kPMG-User-GPID,kPMG-User-GOMailDisclaimer,kPMG-User-GOMailSync

如果我在PowerShell中运行脚本,例如。\ script.ps1 jsmith以'jsmith'作为它的工作参数,但是当使用C#参数时,它不接受参数并且每次都会出现“无法验证参数'Identity'的参数”错误。

我的C#代码中是否有错误导致此参数无法传递给脚本并将其作为输入接受?

答案 0 :(得分:0)

一些想法:

  • C#代码中的参数名称是用户名
  • 脚本中的参数名称为accountIdentity
  • 错误消息引用参数Identity

我认为所有3都应该是一样的。

如果这不是问题,那么调试问题的一种可能方法是将您的C#代码转换为PS脚本。对我来说,至少,我觉得调试一个PS脚本更舒服,我可以快速更改(比如你构建myCommand的地方)并检查它们(使用get-member和select-object *),而不是使用C#。

另外,对于调试,您也可以尝试组合所有单独的PS命令,以便以AddScript()的单个调用结束,而不是使用AddScript()而不是各种AddCommand()。我模糊地记得多年前我写过类似的代码时混淆两者的问题。
