如何在mvc3控制器中获取json数组中的值

本文关键字：json 数组 获取 mvc3 控制器 | 更新日期: 2023-09-27 18:29:30

我有一个包含Json结果的结果。Json结果如下。

      <string xmlns="http://tempuri.org/">
        {"Method":"LOGIN_AUTHENTICATE Start :8/29/2013 1:23:46 AM 
          ASW :8/29/2013 1:23:46 AM P21 :8/29/2013 1:23:50 AM End :8/29/2013 1:23:50AM",
        "ResponseCode":0,"ResponseText":"","HomeBannerURL":"http://example.com/example/",
        "resAccount":[{"shopper_uid":1877,"customer_code":"10950",
         "customer_name":"JASPER ACCOUNT",
         "contact_id":6449,"first_name":"jasper","last_name":"manickaraj",
         "email_address":"exam@example.com","password_hint":"name",
         "default_shipping_method_uid":110,"password":"abc123",
         "default_ship_to_address_id":"150"}],
         "resCategories":
 [{"item_category_uid":123,
        "item_category_desc":"EFG",
        "Total":0,"sub_category_image":"",
        "sub_category_thumb":""},
 {"item_category_uid":1,
        "item_category_desc":"ABC",
        "Total":0,"sub_category_image":"",
        "sub_category_thumb":""},
 {"item_category_uid":2,
        "item_category_desc":"BCD",
        "Total":0,"sub_category_image":"",
        "sub_category_thumb":""},
 {"item_category_uid":3,
        "item_category_desc":"CDE",
        "Total":0,"sub_category_image":"",
        "sub_category_thumb":""}]}
    <string>

现在我把上面的结果分配给var Jsonresult；现在我需要从Jsonresult中获取customer_name，first_name。。如何获得结果。。请帮我解决这个问题。。

如何在mvc3控制器中获取json数组中的值

使用JavaScriptSerializer来实现此功能。首先，您必须定义几个实体，例如。

public class RequestObj
{
    public string Method { get; set; }
    public string ResponseCode { get; set; }
    public string HomeBannerURL { get; set; }
    public IList<Account> ResAccount { get; set; }
}
public class Account
{
    public string shopper_uid { get; set; }
    public string customer_name { get; set; }
    public string first_name { get; set; }
}

其次，您可以反序列化您的字符串。

var scriptSerializer = new JavaScriptSerializer();
var obj = scriptSerializer.Deserialize<RequestObj>(str);

好的，你必须在你的项目中添加json.net dll，你这样写代码：

var obj = JsonConvert.DeserializeObject<Dictionary<string, object>>(str.ToString());
