The API is a little more sophisticated than requiring you to input every single string token manually.

AddCommand() takes the whole command name at once:

powershell.AddCommand('Add-Printer');

For named parameter arguments, use AddParameter() instead of AddArgument() :

powershell.AddParameter("Name", ad);
powershell.AddParameter("PortName", ip)
// etc...

Note that the - that we usually use in front of parameter names in PowerShell scripts is not actually part of the name itself , so don't include that.

If you want to execute multiple pipelines as separate statements, call AddStatement() in between the call to AddCommand() for the first command in the next pipeline:

using (System.Management.Automation.PowerShell powershell = System.Management.Automation.PowerShell.Create())
{
    // call `Add-PrinterPort ...`
    powershell.AddCommand("Add-PrinterPort");
    powershell.AddParameter("Name", printer_ip);
    powershell.AddParameter("PrinterHostAddress", printer_ip);

    // terminate previous statement (equivalent to a newline or `;` in powershell)
    powershell.AddStatement();

    // then call `Add-Printer ...`
    powershell.AddCommand("Add-Printer");
    powershell.AddParameter("Name", printer_name);
    powershell.AddParameter("PortName", printer_ip);
    powershell.AddParameter("DriverName", "Canon Generic Plus PCL6");

    // Invoke the whole thing at once
    powershell.Invoke();
}
