从远程会话返回的PowerShell对象是否不同?

我有一个C#应用程序,它使用Runspaces查询Lync和Exchange PowerShell。如果我在对PowerShell命令行开关具有本地访问权限的服务器上执行应用程序,即安装了管理工具,那么它可以工作;但是,如果我远程连接到服务器,我的foreach逻辑将失败并显示以下错误:

Foreach loop error

示例循环 - 第一个循环正常工作,但是当我向下钻取PS对象时,它在第二个循环失败:

public Collection<PSObject> Workflows;


var wFFilter = _dataService.WorkFlows.ToList();

//foreach (PSObject workflowName in workflowNames)
foreach (dynamic workflowName in wFFilter)
{
    var newWorkflow = new WorkFlowViewModel();
    if (workflowName != null)
    {
        //GetDisplay Name
        newWorkflow.Name = workflowName.Name;

        //Populate IVR options
        foreach (dynamic root in workflowName.DefaultAction.Question.AnswerList)
        {
            if (root.Action.QueueID != null)
            {
                //Do something
            }
        }
    }
}

这让我相信PowerShell对象的返回方式有所不同。可能是这种情况吗?我只是弄清楚为什么这是不同的,以及我如何处理本地和远程返回的对象。

我的PS代码:

private RunspacePool rrp;
public Collection<PSObject> ExecuteSynchronously(string PSCommand, string     RemoteMachineFqdn, int RemoteMachinePort, string RemoteMachinePath,
       bool SslEnabled, string Username, SecureString Password)
    {
        Collection<PSObject> psResult;

        if (rrp == null)
        {
            string shellUri = @"http://schemas.microsoft.com/powershell/Microsoft.PowerShell";
            PSCredential remoteCredential = new PSCredential(Username, Password);
            WSManConnectionInfo connectionInfo = new WSManConnectionInfo(SslEnabled, RemoteMachineFqdn,
                RemoteMachinePort, RemoteMachinePath, shellUri, remoteCredential);

            connectionInfo.SkipRevocationCheck = true;
            connectionInfo.SkipCACheck = true;
            connectionInfo.SkipCNCheck = true;

            rrp = RunspaceFactory.CreateRunspacePool(1, 10, connectionInfo);
            rrp.Open();
        }

        using (PowerShell powershell = PowerShell.Create())
        {
            powershell.RunspacePool = rrp;
            powershell.AddScript(PSCommand);
            psResult = powershell.Invoke();
        }
        return psResult;

    }

谢谢!真的很感激一些帮助:)

它们是不同的,因为它们已在远程会话中序列化,然后在本地会话中反序列化。序列化可能导致对象属性的保真度丢失,以及从对象中删除方法。
