c# - 从 C# 运行 Powershell 脚本

Question

我正在尝试从 C# 代码运行 PowerShell 脚本，但我遇到了一些(可能是环境)问题:

在我尝试运行它的机器上，发生了以下情况:

1. PowerShell 以管理员身份启动并加载
2. PowerShell 窗口立即(显然)无错误关闭

注意事项:

• 脚本有效。当我从 ISE 运行它时，它运行没有错误。
• 如果我右键单击脚本并选择使用 PowerShell 运行，即使我没有在脚本中更改它，我也会收到执行策略错误。

Set-ExecutionPolicy : Windows PowerShell updated your execution policy successfully, but the setting is overridden by a policy defined at a more specific scope. Due to the override, your shell will retain its current effective execution policy of RemoteSigned. Type "Get-ExecutionPolicy -List" to view your execution policy settings. For more information please see "Get-Help Set-ExecutionPolicy". At line:1 char:46 + if((Get-ExecutionPolicy ) -ne 'AllSigned') { Set-ExecutionPolicy -Scope Process ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : PermissionDenied: (:) [Set-ExecutionPolicy], SecurityException + FullyQualifiedErrorId : ExecutionPolicyOverride,Microsoft.PowerShell.Commands.SetExecutionPolicyCommand

• Get-ExecutionPolicy -List

       Scope                ExecutionPolicy
       -----                ---------------
   MachinePolicy              Unrestricted
      UserPolicy                 Undefined
         Process                    Bypass
     CurrentUser              Unrestricted
    LocalMachine              Unrestricted
  

• 我认为这是环保的，因为:

  • 几天前运行良好
  • 在其他电脑上运行良好

这是我用来调用脚本的代码:

if (File.Exists("Start.ps1"))
{
    string strCmdText = Path.Combine(Directory.GetCurrentDirectory(), "Start.ps1");

    var process = System.Diagnostics.Process.Start(@"C:\windows\system32\windowspowershell\v1.0\powershell.exe ", strCmdText);
    process.WaitForExit();
}

脚本本身是无关紧要的，因为我已经把它改成了一个简单的

Write-Host "Hello"
$d=Read-Host

我也有同样的问题。

Answer 1

问题出在脚本的路径上。它在这台特定的机器上有空间，我没有处理过。

窗口关闭太快，看不到任何错误，但设置

process.StartInfo.RedirectStandardOutput = true;

帮我捕获了它。

执行策略与我的错误无关。

为了修复它，我更改了 C# 代码中的路径，如下所述:Executing a Powershell script in CMD.EXE from a location with "Illegal characters in path"

完整代码:

if (File.Exists("Start.ps1"))
            {
                File.GetAttributes("Start.ps1");
                string strCmdText =   Path.Combine(Directory.GetCurrentDirectory(), "Start.ps1");
                var process = new Process();
                process.StartInfo.UseShellExecute = false;
                process.StartInfo.RedirectStandardOutput = true;
                process.StartInfo.FileName = @"C:\windows\system32\windowspowershell\v1.0\powershell.exe";
                process.StartInfo.Arguments = "\"&'"+strCmdText+"'\"";

                process.Start();
                string s = process.StandardOutput.ReadToEnd();
                process.WaitForExit();

                using (StreamWriter outfile = new StreamWriter("StandardOutput.txt", true))
                {
                    outfile.Write(s);
                }

            }
