c# - SharePoint 人物编辑器不显示用户

Question

我有一个要求，我必须将保存的用户显示到 SharePoint 人员编辑器控件。为此，我将用户名保存到 People/Group 列。我正在使用以下代码将这些用户带到人物编辑器控件中:

SetPeopleEditor(item, Constants.FieldNames.IT_DIRECTOR, pe_ITDirector, oWeb);

上述方法的定义如下所示:

        private PickerEntity SetPeopleEditor(SPListItem item, string columnName, PeopleEditor peopleEditor, SPWeb web)
    {
        ArrayList entityArrayList = new ArrayList();
        PickerEntity entity = null;
        if (item[columnName] != null)
        {
            char[] to_splitter = { ';' };
            string to_list = item[columnName].ToString(); // Reads value stored in SPList. (i.e., "Domain\User1; Domain\User2")
            string[] arr = to_list.Split(to_splitter);
            string user = string.Empty;
            for (int i = 1; i < arr.Length; i++)
            {
                if ((i % 2) != 0)
                {
                    user = arr[i].Substring(arr[i].IndexOf("#") + 1);
                    entity = new PickerEntity();
                    entity.Key = user;
                    entity.IsResolved = true;
                    entity = peopleEditor.ValidateEntity(entity);
                    entityArrayList.Add(entity);
                }
            }


        }
        return entity;
    }

但不幸的是，控件总是显示空值。如何通过将数据填充到人员编辑器控件来实现此目的？

您可以按如下方式进行，

SPFieldUserValueCollection userValueCollection =
             new SPFieldUserValueCollection(SPContext.Current.Web, SPContext.Current.Item["ColumnName"] as string);
        if (userValueCollection .Count > 0)
        {
            spPeoplePickerContol.CommaSeparatedAccounts = userValueCollection[0].User.LoginName;
        }
