Question

所以这是powershell：

$app = Get-WmiObject -Class SMS_UserApplicationRequest -Namespace root/SMS/site_sitename -
 ComputerName computername | Select-Object User, Application, RequestGUID

$app

它工作正常，返回信息没有问题。

在c＃中运行：

Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();

PowerShell powerShell = PowerShell.Create();
powerShell.Runspace = runspace;
powerShell.AddScript(script);

Collection<PSObject> results = powerShell.Invoke();

foreach (PSObject result in results)
{
    MessageBox.Show(result.ToString());
}

runspace.Close();

这显示了baseObject，它是UserApplicationRequest，但是如何访问请求中的数据？（那是Select-Object User，Application，RequestGUID）

Answer 1

为了获取Select-Object cmdlet创建的自定义对象，您可以遍历Properties成员：

foreach (var result in results)
{
    foreach ( var property in result.Properties )
    {
        MessageBox.Show( string.Format( "name: {0} | value: {1}", property.Name, property.Value ) );
    }
}

Answer 2

如果您使用的是PowerShell V3（System.Management.Automation.dll 3.0），请不要忘记它现在位于DLR上。这意味着可以通过C＃中的dynamic关键字来使用PSObject：

foreach (dynamic result in results)
{
    var msg = String.Format{"User: {0}, Application: {1}, RequestGUID: {2}", 
                            result.User, result.Application, result.RequestGUID);
    MessageBox.Show(msg);
}
