How to Add More Complex Powershell Commands to Pipeline

Question

I can't seem to run a command like this one...

pshell.AddCommand("(New-Object -ComObject WScript.Network).AddWindowsPrinterConnection(" + strShare + ")");

...without getting an error saying that it cannot find the module. It's expecting me to use something like

pshell.AddCommand("New-Object");
pshell.AddArgument("-ComObject");
pshell.Invoke();

How can I use that format with a command like this?

Try AddScript instead.

      PowerShell shell = PowerShell.Create().AddScript(String.Format("(New-Object -ComObject WScript.Network).AddWindowsPrinterConnection(\"{0}\")",strShare ));

Tried that, just tried it again. It gives me System.Management.Automation.ParseException with a bunch of comments about "unexpected token". I know the command works at the powershell command line.

My bad, another set of escaped quotes was needed.

Here's what I did instead, not sure if this could be written better: PowerShell pshell = PowerShell.Create().AddScript(String.Format("(New-Object -ComObject WScript.Network).AddWindowsPrinterConnection(\"{0}\")", strShare));
