C＃Get CheckedListBox Items ValueMember

Question

很抱歉有分歧，但今天我需要你的帮助......在C＃中！我在这里找不到它。

对于下面的代码，我需要将CheckedItem ValueMember放入richtextbox或string var ...你能帮助我吗？

请注意LogBox是RichtTextBox，我想从checkitems中显示ValueMember。

    // Favorites items
    public class Favorites {
        public string name { get; set; }
        public string url { get; set; }

    // For fav array in json 
    public class GetFav
    {
        public List<Favorites> favoris { get; set; }
    }

    // Member 
    public class ListBox
    {
        public string Text { get; set; }
        public string Value { get; set; }
    }

    // Insert json data in CheckListBox
    private void button2_Click_1(object sender, EventArgs e)
        {
        string fav = @"myjsonfile.json";

        StreamReader sr = new StreamReader(fav);
        string jsonString = sr.ReadToEnd();

        var json = new JavaScriptSerializer().Deserialize<GetFav>(jsonString);
        int i = 0; 
        for(i=0; i< json.favoris.Count; i++)
        {

            chkList.DisplayMember = "Text";
            chkList.ValueMember = "Value";
            chkList.Items.Insert(0, new {Text=json.favoris[i].name,Value=json.favoris[i].url});
        }
    }

    // Need to get the ValueMember and DisplayMember
    private void button3_Click(object sender, EventArgs e)
    {

        int i = 0; 
        for (i=0; i< chkList.CheckedIndices.Count; i++)
        {
            // logBox.Text += chkList.Items[i] + "\n";  show => { Text = Google, Value = google.fr } 
            //logBox.Text += (chkList.Items[i] as ListBox).Value + "\n";  //get an error
        }

    }
}
