您的JSON格式完全一样的模型类。

Your JSON format exactly same as your model class.

当前例如

public class PremisesViewModel
{

    public string createPremisesErrorMessage { get; set; }
    public string updatePremisesErrorMessage { get; set; }

    public SelectList listOfCounties = Initialise.countiesSelectList;

    public Premise premises { get; set; }
}

您JSON像

 var premisesViewModel = {
                                    createPremisesErrorMessage : $('#premises_PremisesDescription').val(),
                                    updatePremisesErrorMessage: $('#premises_OrdnanceSurveyReference').val(),    
                                    premises : {Define more properties here as per your Premise structure}
                                }
