Sharepoint 2013，从列表中获取数据ClientPeoplePicker

在Sharepoint 2013, 我试图从自定义列表中获取用户信息以显示在编辑窗体中，该窗体将显示在控制ClientPeoplePicker中。Sharepoint 2013，从列表中获取数据ClientPeoplePicker

我搜索周围，并用2个解决方案的尝试：

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; 
      //} 
     } 
    }

我叫他们Nintex形式的控制装置：保护覆盖无效OnFormControlDataBinding（对象发件人，EventArgs的）

这是错误我：

我发现我错了:) 这不是在功能，它在我提取该线路的其他

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); 
     } 
    }

：SPContext.Current.Web.EnsureUser（peoplePicker.GetPickerEntity（）。键）扩展方法，然后发生上述错误。

推荐给您的人物吧！

谢谢！
