How to update person or group column with peopleeditor control values

Question

Hi,
I have created custom aspx page and added "PeopleEditor" control(can select multiple users)  in that page. Now I am trying to update person or group column with peopleeditor control values.I am not getting any error if I select single user
in PeopleEditor control but getting error if I select more than one user.
UpdateItem(listItem, "ListColumnName",
listItem.ParentList.ParentWeb.EnsureUser(peopleeditorId.CommaSeparatedAccounts));
Can anybody help me out to resolve the issue?
Thank you in advance!!!
AA.

First get all the users/groups from the PeapleEditor by using PeapleEditor.ResolvedEntities
foreach (PickerEntity pickerEntity in peopleEditor.ResolvedEntities)
SPPrincipalType principalType = (SPPrincipalType)Enum.Parse(typeof(SPPrincipalType), pickerEntity.EntityData["PrincipalType"].ToString());
if (principalType == SPPrincipalType.User || principalType == SPPrincipalType.SecurityGroup)
string loginName = pickerEntity.Key;
//your code here
else if (principalType == SPPrincipalType.SharePointGroup)
string groupName = pickerEntity.Key;
//your code here
Add all the users/groups in an instance of SPFieldUserValueCollection
and then update your list item.
SPFieldUserValueCollection users = new SPFieldUserValueCollection();
users.Add(new SPFieldUserValue(web,user.ID,user.Name));
item["YourUserColumn"] = users;
item.Update();
