How to Pass Command-Line Arguments to PowerShell Scripts from C#?

Execute PowerShell scripts with parameters in C#

To execute a PowerShell script in C# and provide command line arguments, you can follow these steps:

1. Configuring Runspace: Create a RunspaceConfiguration and use it to instantiate a Runspace object. This object represents the PowerShell runtime environment.
2. Create a PowerShell command: Use the Command constructor to convert the script file path to a Command object.
3. Add command line parameters: Use the CommandParameter constructor to create a CommandParameter for each parameter. Add these parameters to the Command's Parameter collection.
4. Building the pipeline: Add the Command object to the Pipeline's Commands collection.
5. Execute the script: Call Pipeline's Invoke method to execute the script and process its output.

Code example:

<code class="language-csharp">// 配置和 Runspace
RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
runspace.Open();

// 带参数的 PowerShell 命令
Command myCommand = new Command(scriptfile);
CommandParameter testParam = new CommandParameter("key", "value");
myCommand.Parameters.Add(testParam);

// 管道和执行
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.Add(myCommand);
var results = pipeline.Invoke();</code>

By following these steps, you can efficiently pass command line parameters from C# to a PowerShell script and properly handle spaces in parameter values.
