Invoking PowerShell Script with Arguments from C#
提问by sh_kamalh
I have a PowerShell script stored in a file. In Windows PowerShell, I execute the script as.\MergeDocuments.ps1 "1.docx" "2.docx" "merge.docx"
我有一个 PowerShell 脚本存储在一个文件中。在 Windows PowerShell 中，我将脚本执行为.\MergeDocuments.ps1 "1.docx" "2.docx" "merge.docx"
I want to call the script from C#. Currently I am using Process.Start as follows which works perfectly:Process.Start(POWERSHELL_PATH, string.Format("-File \"{0}\" {1} {2}", SCRIPT_PATH, string.Join(" ", filesToMerge), outputFilename));
我想从 C# 调用脚本。目前我正在使用 Process.Start 如下，它完美地工作：Process.Start(POWERSHELL_PATH, string.Format("-File \"{0}\" {1} {2}", SCRIPT_PATH, string.Join(" ", filesToMerge), outputFilename));
I want to run it using Pipelineclass, something like the below code but I don't know how to pass the arguments (keep in mind that I don't have named arguments, I am just using $args)
我想使用Pipeline类运行它，类似于下面的代码，但我不知道如何传递参数（请记住，我没有命名参数，我只是使用 $args）
// create Powershell runspace
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
RunspaceInvoke runSpaceInvoker = new RunspaceInvoke(runspace);
runSpaceInvoker.Invoke("Set-ExecutionPolicy Unrestricted");
// create a pipeline and feed it the script text (AddScript method) or use the filePath (Add method)
Pipeline pipeline = runspace.CreatePipeline();
Command command = new Command(SCRIPT_PATH);
command.Parameters.Add("", ""); // I don't have named paremeters
pipeline.Commands.Add(command);
pipeline.Invoke();
runspace.Close();

Just found it in one of the comments to another question
刚刚在另一个问题的评论之一中找到它
In order to pass arguments to the $args pass null as the parameter name, e.g. command.Parameters.Add(null, "some value");
为了将参数传递给 $args 传递 null 作为参数名称，例如 command.Parameters.Add(null, "some value");
The script is called as:.\MergeDocuments.ps1 "1.docx" "2.docx" "merge.docx"
该脚本被称为：.\MergeDocuments.ps1 "1.docx" "2.docx" "merge.docx"
Here is the full code:
这是完整的代码：
class OpenXmlPowerTools
{
static string SCRIPT_PATH = @"..\MergeDocuments.ps1";
public static void UsingPowerShell(string[] filesToMerge, string outputFilename)
{
// create Powershell runspace
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
RunspaceInvoke runSpaceInvoker = new RunspaceInvoke(runspace);
runSpaceInvoker.Invoke("Set-ExecutionPolicy Unrestricted");
// create a pipeline and feed it the script text
Pipeline pipeline = runspace.CreatePipeline();
Command command = new Command(SCRIPT_PATH);
foreach (var file in filesToMerge)
{
command.Parameters.Add(null, file);
}
command.Parameters.Add(null, outputFilename);
pipeline.Commands.Add(command);
pipeline.Invoke();
runspace.Close();
}
}
