Question

在Sharepoint 2013中，我尝试从自定义列表中获取用户信息以在编辑表单中显示，该表单将显示在控件ClientPeoplePicker中。

我四处寻找并尝试了两种解决方案：

private void LoadUserToPeoplePicker(SPListItem item, string colName, ClientPeoplePicker peoplePicker)
    {
        //Get user information from list
        var user = item[colName] as string;

        if (!string.IsNullOrEmpty(user))
        {
            var spUser = new SPFieldUserValue(SPContext.Current.Web, user);

            //Solution 01
            var entity = new PickerEntity();
            entity.Key = spUser.LookupValue;

            PeopleEditor editor = new PeopleEditor();
            entity = editor.ValidateEntity(entity);

            peoplePicker.AddEntities(new List<PickerEntity> { entity });

            //Solution 02
            //if (!string.IsNullOrEmpty(spUser.User.Email))
            //{
            //    peoplePicker.InitialUserAccounts = spUser.User.Email;
            //}
        }
    }

我在覆盖Nintex形式时调用它们：protected override void OnFormControlDataBinding（object sender，EventArgs e）

这是我得到的错误：

任何人都面临着这个问题，请帮助。

Answer 1

我发现我错了:) 它不在那个功能中，它在另一个

private void ExtractValueForApprover(IOrderedDictionary dictionary, ClientPeoplePicker peoplePicker,
        string colName)
    {
        if (peoplePicker == null || string.IsNullOrEmpty(colName))
        {
            return;
        }

        if (peoplePicker.ResolvedEntities.Count > 0)
        {
            var user = SPContext.Current.Web.EnsureUser(peoplePicker.GetPickerEntity().Key);

            AddValueToDictionary(colName, user.LoginName, dictionary);
        }
    }

我提取了这一行：SPContext.Current.Web.EnsureUser（peoplePicker.GetPickerEntity（）。Key）到扩展方法，然后发生上面的错误。

这对你们有帮助。

谢谢！
