Sharepoint c# retrieve all site and subsite

Question

I'am trying to retrieve all site and subsite in sharepoint but i get access denied.

I read about to use GetSubwebsForCurrentUser() property, but i get the same message.

My code is the next

            foreach (SPWebApplication webApp in SPWebService.ContentService.WebApplications)
            {                    
                foreach (SPSite siteCollection in webApp.Sites)
                {
                    foreach(SPWeb web in siteCollection.RootWeb.GetSubwebsForCurrentUser())
                    {
                       dropDownSite.Items.Add(web.Url);
                    }


                }
            }

please i need help! Thanks!

You will probably need to call SPSecurity.RunWithElevatedPrivileges(delegate())

You could do an inline delegate if you wish, something like:

SPSecurity.RunWithElevatedPrivileges(delegate() 
{
    foreach (SPWebApplication webApp in SPWebService.ContentService.WebApplications)
    {                    
        foreach (SPSite siteCollection in webApp.Sites)
        {
            foreach(SPWeb web in siteCollection.RootWeb.GetSubwebsForCurrentUser())
            {
                 dropDownSite.Items.Add(web.Url);
            }
        }
    }
});

Just to make sure, is this code running on the server that is hosting the Sharepoint portal? What version of Sharepoint are you running?

Also, would it make sense to use the Webservices that Sharepoint exposes? http://msdn.microsoft.com/en-us/library/aa979690(v=office.12).aspx

If you are running this code on the same server as SP, then make sure that your credentials have access to SP. If you are calling this from a website, also make sure that you are not running as "Anonymous".

Over all, I think taking advantage of the webservices is the easiest way to get it working. But make sure that you have the right permissions being sent and that that user has access (in the SP configurations) to that data.

Hope that helps!
