如何在 .NET MVC 中解析复杂的 JSON

Question

我正在通过 ajax 将 JSON 对象传递到我的 MVC 控制器。 JSON 有效。我在第一行的 MVC 控制器中有一个断点。当我检查控制器中的变量 addOnModel 时，基本级别的属性设置正确。 ProductCodeList 属性具有正确数量的元素，但所有值都显示为 null。

我曾尝试更改元素的名称以使它们更独特，但这似乎没有帮助。

{"AddOnID": "0","LocaleID": "63", "Name": "FirstAddOn", "Text": "testText", "ProductCodeList": [ {"AddOnSort": 0, "AddOnProductCode": "product1"}]}

$.ajax({
contentType: 'application/json;',
dataType: 'json',
type: 'POST',
url: '/AddOn/UpsertAddOn',
data: data,
success: function () {
alert('Finished.');
}
});

/// <summary>
/// Object model from web page
//// </summary>
public class AddOnModel
{
    public int AddOnID { get; set; }
    public int LocaleID { get; set; }
    public string Text { get; set; }
    public string Name { get; set; }
    /// <summary>
    /// This is the attribute that won't populate correctly. The number
    /// of attributes in the array is correct, but all of its values
    /// come across as null. This is what I'm trying to fix.
    /// </summary>
    public List<AddOnProductModel> ProductCodeList { get; set; }
}

/// <summary>
/// Holds code and sort order. 
/// </summary>
public class AddOnProductModel
{
    int? AddOnSort { get; set; }
    string AddOnProductCode { get; set; }
}

我的控制器片段

    /// <summary>
    /// Upsert the add on.
    /// </summary>
    /// <param name="addOnModel">Model from the web page.</param>
    /// <returns></returns>
    [HttpPost]
    public ActionResult UpsertAddOn(AddOnModel addOnModel)
    {
        AddOn actualAddOn = new AddOn();
        if (addOnModel.AddOnID > 0)
        {
            //Load from DB Repository here.
        }
        //Rest of my class removed
     }

Answer 1

AddOnProductModel 中的属性不是 public。

制作它们public

public class AddOnProductModel
{
    public int? AddOnSort { get; set; }
    public string AddOnProductCode { get; set; }
}
