c# - 当我在 localhost 上创建 RunSpace 而不提供 runspaceconnectioninfo 时，某些 PowerShell 模块（Cluster cmdlet）不会被加载

Question

请参考以下示例： RunspaceSample(string.Empty); 失败并出现“Add-VMToCluster”一词未被识别为 cmdlet 的名称。而 RunspaceSample("localhost") 或 RunspaceSample("somecomputerName") 成功。任何指针为什么是它？包括 RunspaceConnectionInfo 是否会更改使用的 powershell 版本或用于执行的 RunspaceConfiguration ？此外，如果我使用带有 ComputerName = "localhost" 的 RunSpaceConnectionInfo 创建 Runspace，即使在本地计算机上执行 powershell 脚本，也会对性能产生什么影响？

谢谢

public static void RunspaceSample(string computerName)
    {
        Runspace rs;
        if (string.IsNullOrEmpty(computerName))
        {
            rs = RunspaceFactory.CreateRunspace();
        }
        else
        {
            var connectionInfo = new WSManConnectionInfo
            {
                OperationTimeout = 10000,
                OpenTimeout = 10000,
                ComputerName = computerName
            };
            rs = RunspaceFactory.CreateRunspace(connectionInfo);
        }

        rs.Open();
        PowerShell ps = PowerShell.Create();
        ps.Runspace = rs;
        string script = @"$ComputerName = 'somevm'; $null = Add-VMToCluster -Name $ComputerName -VMName $ComputerName -ErrorAction SilentlyContinue -verbose";
        ps.AddScript(script);


        Console.WriteLine("Script: {0}", script);
        Console.WriteLine("------------------------");
        foreach (PSObject result in ps.Invoke())
        {
            Console.WriteLine(result.ToString());
        }

        if (ps.HadErrors)
        {
            var sb = new StringBuilder();
            foreach (var errorRecord in ps.Streams.Error)
            {
                sb.AppendFormat("\nError: {0} CategoryInfo: {1}", errorRecord.Exception.Message, (errorRecord.CategoryInfo != null) ? errorRecord.CategoryInfo.ToString() : string.Empty);
            }

            var errorMessage = sb.ToString();
            Console.WriteLine(errorMessage);
        }
    }

FailoverClusters 模块仅在 64 位 PowerShell 会话中可用。将此程序集作为 64 位程序集解决了找不到模块的问题。
