使用C#中的invoke命令引发异常

我已从powershell终端尝试了以下案例：

invoke-command -connectionuri "http://FullMachineName/wsman" -configuration "http
://schemas.microsoft.com/powershell/Microsoft.PowerShell" -credential "MachineName\Administrator" -filepath "C:\scripts\get
Users.ps1"

这很好用。 但当我通过C#的invoke命令尝试同样的事情时，它抛出了以下异常：

System.Management.Automation.CmdletInvocationException was unhandled

我正在使用以下代码进行尝试：

String file = @"C:\scripts\getUsers.ps1";
PowerShell ps = PowerShell.Create()
PSCommand cmd = new PSCommand();                
cmd.AddCommand("Invoke-Command");
cmd.AddParameter("CONNECTIONURI", "http://FullMachineName/wsman");
cmd.AddParameter("FILEPATH",file);
cmd.AddParameter("CREDENTIAL", Credential);            
cmd.AddParameter("CONFIGURATION","http://schemas.microsoft.com/powershell/Microsoft.PowerShell" );
ps.Commands = cmd;                
Runspace runSpace = RunspaceFactory.CreateRunspace();
runSpace.Open();
ps.Runspace = runSpace;
psObjects = ps.Invoke();

此场景中的典型问题是，您在PowerShell中为32位或64位版本的PowerShell运行了Set ExecutionPolicy，但不是同时为这两个版本运行。您正在运行的C#程序可能是您没有更改PowerShell默认执行策略的程序。尝试同时打开32位和64位PowerShell会话，并确保执行策略设置为RemoteSigned或Unrestricted。

尝试使用PowerShell实例设置和获取set ExecutionPolicy Unrestricted

 public static ICollection<PSObject> RunScriptText(string scriptFullPath, ICollection<CommandParameter> parameters = null)
        {
            var runspace = RunspaceFactory.CreateRunspace();
            runspace.Open();
            var pipeline = runspace.CreatePipeline();

            using (PowerShell PowerShellInstance = PowerShell.Create())
            {
                var initial = InitialSessionState.CreateDefault();
                Console.WriteLine("Importing ServerManager module");
                initial.ImportPSModule(new[] { "ServerManager" });

                PowerShellInstance.Runspace = runspace;

                PowerShellInstance.AddScript("Set-ExecutionPolicy Unrestricted");
                PowerShellInstance.AddScript("Get-ExecutionPolicy");
                PowerShellInstance.Invoke();

                var cmd = new Command(scriptFullPath);
                if (parameters != null)
                {
                    foreach (var p in parameters)
                    {
                        cmd.Parameters.Add(p);
                    }
                }
                pipeline.Commands.Add(cmd);
                var results = pipeline.Invoke();
                pipeline.Dispose();
                runspace.Dispose();
                return results;
            }
            return null;
        }

公共静态ICollection RunScriptText（字符串scriptFullPath，ICollection参数=null）
{
var runspace=RunspaceFactory.CreateRunspace（）；
Open（）；
var pipeline=runspace.CreatePipeline（）；
使用（PowerShell PowerShellInstance=PowerShell.Create（））
{
var initial=InitialSessionState.CreateDefault（）；
WriteLine（“导入服务器管理器模块”）；
initial.ImportPSModule（新[]{“ServerManager”}）；
PowerShellInstance.Runspace=运行空间；
PowerShellInstance.AddScript（“设置执行策略不受限制”）；
AddScript（“获取执行策略”）；
PowerShellInstance.Invoke（）；
var cmd=新命令（scriptFullPath）；
if（参数！=null）
{
foreach（参数中的var p）
{
cmd.Parameters.Add（p）；
}
}
pipeline.Commands.Add（cmd）；
var results=pipeline.Invoke（）；
pipeline.Dispose（）；
Dispose（）；
返回结果；
}
返回null；
}

尝试使用32位windows powershell的RemoteSigned和Unrestricted执行策略。仍会收到相同的错误。请尝试将应用程序编译为x86。我在powershell 32位终端中直接尝试了invoke命令，但遇到了问题中提到的异常。如果在该shell中运行Get ExecutionPolicy，它是否返回

受限
？如果是这样，您需要运行（在提升的32位PowerShell中）
设置ExecutionPolicy Unrestricted
。
