c# - 从 C# 应用程序调用 azure powershell cmdlet 失败

Question

我试图自动化部署到 azure 云的过程。我的 powershell 脚本可以做到这一点，当从 azure powershell 命令行执行它时，它的工作方式就像一个魅力。当我尝试从 C# 应用程序调用相同的脚本时，它失败了。

这是我的代码:

  internal  void RunPowerShellScript(string scriptPath, Dictionary<string, string> arguments)
    {
        RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
        Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
        runspace.Open();
        RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
        Pipeline pipeline = runspace.CreatePipeline();
        //Here's how you add a new script with arguments            
        Command myCommand = new Command(scriptPath, true);
      foreach (var argument in arguments)
        {
            myCommand.Parameters.Add(new CommandParameter(argument.Key, argument.Value));
        }            
        pipeline.Commands.Add(myCommand);
        var results = pipeline.Invoke();
        foreach (var psObject in results)
        {
            _view.PrintOutput(psObject.ToString());
        }
    }

我也关注了其他线程，例如这个:Execute PowerShell Script from C# with Commandline Arguments这个: passing parameters to powershell from c#

但似乎没有任何作用。我收到以下错误:

无法验证参数“PublishSettingsFile”的参数。参数为 null 或为空。提供一个不为 null 或空的参数，然后重试该命令。

我相信您传递publishsettings文件的方式导致了这个问题。传递publishsettings文件时，您必须添加引号，如果没有引号，您将遇到异常。

以下是基于您的代码的代码，我通过使用 (\") 传递带有引号的发布设置文件来测试它，它工作正常:

private void button1_Click(object sender, EventArgs e)
{
  Dictionary<string, string> myDict= new Dictionary<string, string>();
  myDict.Add("-subscriptionDataFile", "\"C:\\InstallBox\\asc.publishsettings\"");
  RunPowerShellScript("C:\\InstallBox\\testcode.ps1", myDict);
}

internal void RunPowerShellScript(string scriptPath, Dictionary<string, string> arguments)
 {
   RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
   Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
   runspace.Open();
   RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
   Pipeline pipeline = runspace.CreatePipeline();
   //Here's how you add a new script with arguments            
   Command myCommand = new Command(scriptPath);
   foreach (var argument in arguments)
   {
      myCommand.Parameters.Add(new CommandParameter(argument.Key, argument.Value));
   }
   pipeline.Commands.Add(myCommand);
   var results = pipeline.Invoke();
   foreach (var psObject in results)
    {
      .........
    }
   }

我的 testcode.ps1 如下:

Param(  [string]$subscriptionDataFile)
Import-Module Azure
Import-AzurePublishSettingsFile subscriptionDataFile
Get-AzureSubscription

为了确保我可以看到您的问题，如果我将字典键值对更改为如下(不带引号)，我会得到与您描述的完全相同的错误:

myDict.Add("-subscriptionDataFile", "C:\\InstallBox\\asc.publishsettings");

所以传递PublishSettings文件的正确方法如下:

myDict.Add("-subscriptionDataFile", "\"C:\\InstallBox\\asc.publishsettings\"");
