Question

Can anyone try getting the username and email of all the users in a Array of the People picker control in SharePoint 2010?

If so can you provide me a Method this?

The method should have parameters like (sharepointgroupname,sharepoint user)

I have tried Like This. But it returns only one user name and email address from people picker control. I want to retrieve for multiple users Sharepoint group and Active Directory group. Please help me.

 private void GetNameAndEmailFromPeoplePicker(SPListItem mySourceListItem, out String PeoplePicker, out String CCPeoplePicker, out String UserName)
        {
            PeoplePicker = "";
            CCPeoplePicker = "";
            UserName = "";
            try
            {

                SPFieldUserValueCollection Users = new SPFieldUserValueCollection(mySiteWeb, Convert.ToString(mySourceListItem["Point of Contact"]));
                foreach (SPFieldUserValue User in Users)
                {
                    UserName = User.User.Name;
                    PeoplePicker = User.User.Email;
                }
                SPFieldUserValueCollection BCCUsers = new SPFieldUserValueCollection(mySiteWeb, Convert.ToString(mySourceListItem["Backup Point of Contact"]));
                foreach (SPFieldUserValue BCCUser in BCCUsers)
                {
                    CCPeoplePicker = BCCUser.User.Email;
                }
            }

            catch (Exception ex)
            {
                UlsLogs.LogErrorInULS(ex.InnerException.ToString(), TraceSeverity.High);
            }
        }
