将参数传递到PowerShellScript的文件路径

Question

Trying to pass the argument(s) or list of argument to PowerShell Script Path while executing it through C# function.

I am using a C# function to get the list of details from my script via a function that uses System.Management.Automation library to invoke powershell command. I am passing file path thus the script is working perfectly fine when it does not requires any argument, however when I need to pass them it is giving User-UnHandled Exeption.

Value in the scriptPath Variable:

C:\Users\<username>\source\repos\MyProject\Shell\Get-SDC.ps1 'Test - Group'

My function:

private string PowerShellExecutorStr(string scriptPath)
    {
        string outString = "";
        var shell = PowerShell.Create();
        shell.Commands.AddCommand(scriptPath);
        var results = shell.Invoke();
        if (results.Count > 0)
        {
            var builder = new StringBuilder();
            foreach (var psObj in results)
            {
                builder.Append(psObj.BaseObject.ToString() + "\r\n");
            }
            outString = Server.HtmlEncode(builder.ToString());
        }
        shell.Dispose();
        return outString;
    }

Script:

param($GroupName)
<Get-ADGroup Command to fetch Details of the Group using $GroupName as Parameter>

outString needs to fetch the output of the PowerShell Script when the arguments are passed to it.

Answer 1

Use Add Parameter

var shell = PowerShell.Create();
shell.Commands.AddCommand(scriptPath)
              .AddParameter("ParamName", "ParamValue");
var results = shell.Invoke();

The above is equivelent to to following PowerShell:

PS> scriptPath -ParamName ParamValue

Here's a breakdown in the documentation

Answer 2

Another way that I found through Archer's link is to add argument

private string PowerShellExecutorStr(string script, string arg)
        {
            string outString = "";
            var shell = PowerShell.Create();
            shell.Commands.AddCommand(script);
            shell.Commands.AddArgument(arg);    // <----- Using this statement
            var results = shell.Invoke();
            ……rest of the code
        }
