我有代码试图让lync会话运行PowerShell脚本形式c#。当试图运行脚本“$ CSSession = New-CsOnlineSession -Credential $ cred \ n”我得到空引用异常。

代码是:
public static void GetLyncUsers(string userName, string plainPassword)
{
RunspaceConfiguration config = RunspaceConfiguration.Create();
using (Runspace myRs = RunspaceFactory.CreateRunspace(config))
{
myRs.Open();
RunspaceInvoke scriptInvoker = new RunspaceInvoke(myRs);
scriptInvoker.Invoke("Set-ExecutionPolicy Unrestricted");
using (PowerShell powerShellInstance = PowerShell.Create())
{
powerShellInstance.Runspace = myRs;
// Import module.
powerShellInstance.Commands.AddCommand("Import-Module")
.AddArgument(

powerShellInstance.Invoke();

// Run the script
var script = string.Format(
"$CSSession = New-CsOnlineSession -Credential $cred\n");
powerShellInstance.AddScript(script);
Collection<PSObject> psOutput = powerShellInstance.Invoke(); //Getting exception here.
// check the other output streams (for example, the error stream)
if (powerShellInstance.Streams.Error.Count > 0)
{
// error records were written to the error stream.
// do something with the items found.
}
}
}
}

我被告知我的MS支持,目前不支持从C#调用Lync Online PowerShell脚本。
