Question

I created several groups using the following code:

                SPWeb currentSite = SPContext.Current.Web;
                currentSite.EnsureUser(groupOwner);
                currentSite.SiteGroups.Add(siteTitle1, currentSite.SiteUsers[groupOwner],
                currentSite.SiteUsers[groupOwner], siteDescription1);

How can I assign these groups to a specific subsite?

Answer 1

You should get a subsite object, like this:

var subWeb = currentSite.Webs["MySubSite"];

And then use your code:

subWeb.EnsureUser(groupOwner);
subWeb.SiteGroups.Add(siteTitle1, currentSite.SiteUsers[groupOwner],
            subWeb.SiteUsers[groupOwner], siteDescription1);
