JSON到Devexpress Winforms LookUpEdit控件

Question

我的JSON文件内容如下：

{

  01: "One",

  02: "Two",

  03: "Three",

  04: "Four",

  05: "Five",

  06: "Six",

  07: "Seven",

  08: "Eight",

  09: "Nine",

  10: "Ten"

}

我正在使用Newtonsoft.Json图书馆。我这样尝试过：

    var json = File.ReadAllText(@"numbers.json");

    var array = JObject.Parse(json);

    lookUpEdit1.Properties.DropDownRows = array.Count > 10 ? 10 : array.Count;

    lookUpEdit1.Properties.DisplayMember = "Key";

    lookUpEdit1.Properties.ValueMember = "Value";

    lookUpEdit1.Properties.DataSource = array.ToList();

    lookUpEdit1.Properties.Columns.Add(new LookUpColumnInfo("Key"));

它给出了这样的错误： 'JObject' does not contain a definition for 'ToList' and no extension method 'ToList' accepting a first argument of type 'JObject' could be found (are you missing a using directive or an assembly reference?)

如何从JSON文件填写Devexpress Winforms LookUpEdit？
