我无法在c#程序中运行Skyline PowerShell脚本

我正在尝试在C#上的程序中运行此Skyline脚本。 也有例外。 脚本在PowerShell命令行中运行良好

using (var powerShellInstance = PowerShell.Create())
{
    powerShellInstance.Commands
        .AddCommand("Import-Module")
        .AddArgument("SkypeOnlineConnector");

    var script = 
        "$Username =\"username\"\n" + 
        "$Password =\"password\"\n" +
        "$secpasswd = ConvertTo-SecureString $Password -AsPlainText -Force\n" +
        "$cred = new-Object System.Management.Automation.PSCredential ($Username, $secpasswd)\n" +
        "$CSSession = New-CsOnlineSession -Credential $cred\n" +
        "Import-PSSession $CSSession -AllowClobber\n" + 
        "Get-CsOnlineUser";

    powerShellInstance.AddScript(script);
    powerShellInstance.Invoke();
}

此it结果异常：
