javascript - 将 javascript 对象数组发送到 MVC4 Controller

Question

这是我的 Controller 操作:

public ActionResult BrowsePartial(IList<SearchParam> searchParams = null)
{
   //...
}

这是对象模型:

public class SearchParam
{
    public string Order { get; set; }
    public string Type { get; set; }
    public string Value { get; set; }
}

这是我向 Controller 发送数据的方式:

$.ajax(
{
   type: "GET",
    url: url,
    data: { searchParams: [{ Order: "fghfdhgfdgfd", Type: "sasdsa", Value: "saddsadsads" }, { Order: "fghfdhgfdgfd", Type: "sasdsa", Value: "saddsadsads" }, { Order: "fghfdhgfdgfd", Type: "sasdsa", Value: "saddsadsads" }] },
    mode: "replace",
    cache: false,
 });

现在，当我调试该操作时，我有一个 IList<SearchParam>这是用 3 个元素正确初始化的。但是，每个 SearchParam 的字段对象( Order 、 Type 和 Value )被初始化为 null。这里可能出现什么问题？

我认为，在单个请求中发送数组参数的唯一方法是将其字符串化，然后在 Controller 中反序列化。

$.ajax(
{
   type: "GET",
    url: url,
    data: { searchParams: JSON.stringify([{ Order: "fghfdhgfdgfd", Type: "sasdsa", Value: "saddsadsads" }, { Order: "fghfdhgfdgfd", Type: "sasdsa", Value: "saddsadsads" }, { Order: "fghfdhgfdgfd", Type: "sasdsa", Value: "saddsadsads" }])},
    mode: "replace",
    cache: false,
 });


public ActionResult BrowsePartial(string searchParams = null)
{
    SearchParam params = JsonConvert.DeserializeObject<SearchParam>(searchParams);
}

但我可能错了;)
