尝试从 C# 运行 powershell 脚本时出错

Question

我有一个 powershell 脚本，当在 powershell 中运行时运行没问题，但当尝试从 c# 运行时抛出错误。 powershell 脚本正在尝试连接到 lync online(skype for business) 并列出 lync 在线用户。

这是从 c#

调用 powershell 脚本的代码

        public static void ImportLyncUsers()
    {

        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(
                        @"C:\Program Files\Common Files\Microsoft Lync Server 2013\Modules\LyncOnlineConnector\LyncOnlineConnector.psd1");
                powerShellInstance.Invoke();
                powerShellInstance.Commands.Clear();
                var filePath = @"F:\PresensoftNewTrunk\Trunk\Lync Archiver\Exchange\Scripts\ImportUsers.ps1";
                powerShellInstance.Commands.AddScript(System.IO.File.ReadAllText(filePath));


                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.
                }
            }
        }

    }

这是我在尝试从 c# 运行 ps 脚本时遇到的错误。

这是 ps 脚本的一部分

 $secpasswd = New-Object -TypeName System.Security.SecureString
    $password = [LyncFoundation.Helpers.StringHelper]::Decrypt($exchangeServer.Password);
    $password.ToCharArray() | ForEach-Object { $secpasswd.AppendChar($_) }
    $cred = New-Object System.Management.Automation.PSCredential ($exchangeServer.UserName,$secpasswd)

    #Get Lync Users
    Import-Module LyncOnlineConnector
    try{
    $CSSession = New-CsOnlineSession -Credential $cred
    }
    catch [System.Net.WebException]{

        if ($_.Exception.Message.Contains("Unable to query AutoDiscover")){
            $CSSession = New-CsOnlineSession -Credential $cred -OverridePowershellUri https://admin0a.online.lync.com/OcsPowershellLiveId
        }
        else{
          throw $_.Exception
        }
    }

我想知道为什么脚本运行在直接从 powershell 执行时很顺利，但在尝试从 c# 调用时却给我错误。我需要设置什么样的环境才能通过这个错误？

Answer 1

代码看起来不错。我遇到了类似的问题，因为 PowerShell 的 Lync Online 是 64 位的，所以你必须为该平台 编译而不是默认的 Any CPU.
