Question

I've done hard research and trying to solve my problem. 3 days googling and asking now i ended up with this :

private void ManipulateGPO(){
    GPDomain domain = new GPDomain("sh.dom");
    Gpo gpo_background = domain.CreateGpo("testingGPO");
}

the code above create a GPO successfully. but i need to link it to an OU?

any help will be appreciated.

You use the SOM (Scope of Management) class to link to the OU

using Microsoft.GroupPolicy;

private void ManipulateGPO(){
    GPDomain domain = new GPDomain("sh.dom");
    Gpo gpo_background = domain.CreateGpo("testingGPO");
    Som som = domain.GetSom("The path of the SOM specified as a fully qualified distinguished name, for example, (ou=MyOU,dc=contoso,dc=com)");
    som.LinkGpo(-1, gpo_background);
}
