  • can you please explain which part of your code has issues? it seems to write json to file. – ASh Aug 20 '18 at 11:06
  • @ASh It Doesn't save to Json file as there is a RelayCommand property and i also dont want to save that. I want to save only two property values which is mentioned above – Shanto Siddiq Aug 20 '18 at 11:26

You can try to SerializeObject by anonymous class then carry your expect property instead of SetUpViewModel object.

private void SaveCommand()
{
    string strJsonResult = JsonConvert.SerializeObject(
        new {
            SelectedScalesModel = this.SelectedScalesModel,
            SelectedScalesPort = this.SelectedScalesPort
        }
    );
    File.WriteAllText("setup.json", strJsonResult);
    MessageBox.Show("File save in Json Format");
}

Note

use this because your property info in your object.
