c# - 使用 C# 中的调用命令抛出异常

Question

我从 powershell 终端尝试了以下情况:

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

这工作正常。 但是，当我通过 C# 的调用命令尝试相同的操作时，它会抛出以下异常:

System.Management.Automation.CmdletInvocationException was unhandled
  Message=File C:\scripts\getUsers.ps1 cannot be loaded because the execution of scripts is disabled on this system. Please see "get-help about_signing" for more details.

我正在尝试使用以下代码:

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已在 PowerShell 中为 32 位或 64 位版本的 PowerShell 运行 Set-ExecutionPolicy，但不能同时运行这两者。您正在运行的 C# 程序可能是您没有更改 PowerShell 的默认执行策略的位。尝试打开 32 位和 64 位 PowerShell session ，并确保执行策略设置为 RemoteSigned 或 Unrestricted。
