I am trying to create a new SharePoint group programmatically (using .Net), for this I am using the following C# code

            //greate group with no users:

            web.SiteGroups.Add(groupName, groupOwner, null, description);
            //Parameters are defined earlier in the code such as:
            //   string groupName
            //   SPUser groupOwner
            //   string description

            SPGroup newGroup = web.Groups.GetByName(groupName);

The creation works well but when I try to access the group an exception is thrown saying "Group cannot be found." What is the reason that the group can not be found and how can I fix this (I need to access the group for my further code)? If I check on the SharePoint under People and Groups the group is there.

Any help is appreciated, thanks.

  • I'm not 100% sure, but I'm guessing it's because you are using old SPWeb object which doesn't have new group in it's properties. Dispose old object and create new one.

Try this : SPGroup oGroup = web.SiteGroups["Original_Name"];

  • Thank you for the quick reply. That is what I had originally with the same result that an exception was thrown. May 22, 2014 at 10:02
  • Please check waht following methods return :private bool GroupExistsInWebSite(SPWeb web, string name) { return web.Groups.OfType<SPGroup>().Count(g => g.Name.Equals(name, StringComparison.InvariantCultureIgnoreCase)) > 0; } private bool GroupExistsInSiteCollection(SPWeb web, string name) { return web.SiteGroups.OfType<SPGroup>().Count(g => g.Name.Equals(name, StringComparison.InvariantCultureIgnoreCase)) > 0; }

  • This web.SiteGroups[groupName]; works for me. web.Groups[groupName] was throwing exception Group cannot be found
