问题调用从C＃一个PowerShell功能 [英] Problem with calling a powershell function from c#

问题描述

我试图调用一个函数在PowerShell中的文件如下：

I'm trying to call a function in a powershell file as follows:

    string script = System.IO.File.ReadAllText(@"C:\Users\Bob\Desktop\CallPS.ps1");

    using (Runspace runspace = RunspaceFactory.CreateRunspace())
    {
        runspace.Open();
        using (Pipeline pipeline = runspace.CreatePipeline(script))
        {
            Command c = new Command("BatAvg",false); 
            c.Parameters.Add("Name", "John"); 
            c.Parameters.Add("Runs", "6996"); 
            c.Parameters.Add("Outs", "70"); 
            pipeline.Commands.Add(c); 

            Collection<PSObject> results = pipeline.Invoke();
            foreach (PSObject obj in results)
            {
                // do somethingConsole.WriteLine(obj.ToString());
            }
        }
    }

PowerShell的功能在CallPS名为.ps1：

The powershell function is in CallPS.ps1:

Function BatAvg
{
    param ($Name, $Runs, $Outs)
    $Avg = [int]($Runs / $Outs*100)/100 
    Write-Output "$Name's Average = $Avg, $Runs, $Outs "
}

我得到了以下异常：

术语BatAvg'未被识别为cmdlet，函数，脚本文件或可操作的程序的名称。

The term 'BatAvg' is not recognized as the name of a cmdlet, function, script file, or operable program.

我在做什么错了，我承认，我所知甚少关于PowerShell的

What am I doing wrong, I admit, I know very little about PowerShell.

推荐答案

这似乎为我工作：

using (Runspace runspace = RunspaceFactory.CreateRunspace())
        {
            runspace.Open();
            PowerShell ps = PowerShell.Create();
            ps.Runspace = runspace;
            ps.AddScript(script);
            ps.Invoke();
            ps.AddCommand("BatAvg").AddParameters(new Dictionary<string, string>() {
                {"Name" , "John"}, {"Runs", "6996"}, {"Outs","70"}
            });
            foreach (PSObject result in ps.Invoke())
            {
                Console.WriteLine(result);
            }
        }
