sharepoint 2010 从PeopleEditor控件中取出多用户,并返回SPFieldUserValueCollection

如果一个列表中有一个字段类型为用户或用户组，并且设置为用户，允许多值的话，那么用代码进行更新的时候就必须将这个字段的值赋成SPFieldUserValueCollection类型，以下代码即为从PeopleEditor控件中取出多个用户并返回一个SPFieldUserValueCollection类型的值：

    public SPFieldUserValueCollection GetUsersValue(PeopleEditor pe)

        {

            SPFieldUserValueCollection result = new SPFieldUserValueCollection();

            using (SPSite mySite = new SPSite(SPContext.Current.Site.ID))

            {

                using (SPWeb myWeb = mySite.RootWeb)

                {

                    if (pe.CommaSeparatedAccounts != "")

                    {

                        foreach (string item in pe.CommaSeparatedAccounts.Split(','))

                        {

                            SPUser u = myWeb.EnsureUser(item);

                            SPFieldUserValue uservalue = new SPFieldUserValue(myWeb, u.ID, u.Name);

                            result.Add(uservalue);

                        }

                    }

                }

            }

            return result;

        }
