来自powershell脚本的C＃get变量

Question

如何从ac＃应用程序获取powershell变量$ test？

我试过这样的：

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(scriptFile);
CommandParameter testParam = new CommandParameter("key", "value");
CommandParameter testParam2 = new CommandParameter("key", "value");
CommandParameter testParam3 = new CommandParameter("key", "value");
myCommand.Parameters.Add(testParam);
myCommand.Parameters.Add(testParam2);
myCommand.Parameters.Add(testParam3);

pipeline.Commands.Add(myCommand);

// Execute PowerShell script
var results = pipeline.Invoke();
var resultVariable = runspace.SessionStateProxy.PSVariable.GetValue("test");

resultVariable为null 。 但我在powershell中用int填充它（即$ test = 4）。

在脚本中使用$global:test=4或在同一范围内运行脚本。 默认情况下，脚本在其自己的作用域中运行，因此在脚本中更改的任何变量在外部都不可见
