Question

我有一个json字符串，如下所示

string json = "{\"Method\":\"LOGIN\",\"Skill\":{\"1\":\"SKILL-1\",\"2\":\"SKILL-2\"}}";

我正在使用JavaScriptSerializer来解析json

System.Web.Script.Serialization.JavaScriptSerializer oSerializer = 
                               new System.Web.Script.Serialization.JavaScriptSerializer();
var dict = oSerializer.Deserialize<Dictionary<string,object>>(json);

我正在使用以下行<{1}}

Method = LOGIN

但是如何让Skill成为一个循环。喜欢

技能

MessageBox.Show("Method = "+dict["Method"].ToString());

Answer 1

你应该申报自己的班级：

public class YourClassName
{
    public string Method { get; set; }
    public Dictionary<int, string> Skill { get; set; }
}

并反序列化Json字符串，如下所示：

var obj = oSerializer.Deserialize<YourClassName>(json);

Answer 2

映射到Skill密钥的值实际上是另一个Dictionary<string, object>。您可以通过转换object：

来迭代它

string json = "{\"Method\":\"LOGIN\",\"Skill\":{\"1\":\"SKILL-1\",\"2\":\"SKILL-2\"}}";

var oSerializer = new JavaScriptSerializer();
var dict = oSerializer.Deserialize<Dictionary<string,object>>(json);

var innerDict = dict["Skill"] as Dictionary<string, object>;

if (innerDict != null)
{
   foreach (var kvp in innerDict)
   {
       Console.WriteLine ("{0} = {1}", kvp.Key, kvp.Value);
   }
}

或者，另一种方法是将您的对象映射到适当的class并反序列化到它而不是通用的Dictionary<string, object>。

Answer 3

假设您有以下课程

public class Data
{
     public string Method { get; set; }
     public Skills Skill { get; set; }
     // If you don't want to use Skills class then you can use this
     //public Dictionary<int, string> Skills { get; set; }
}
public class Skills
{
     public int Id { get; set; }
     public string Skill { get; set; }
}

因此，您可以将json反序列化为Data对象

Data deserializedData = JsonConvert.DeserializeObject<Data>(json);
