类与json的互相转化(c#)

1 // JavaScriptSerializer需添加dll引用，System.Web.Extensions
2 //Class转json字符串
3 JavaScriptSerializer serializer = new JavaScriptSerializer();
4 var json = serializer.Serialize(obj);
5  
6 //将json字符串在转为原先的类，JsonConvert需添加第三方dll,Newtonsoft.Json.dll
7 var model=JsonConvert.DeserializeObject<ProductModel>(json);

 1 string response = "{'name':'jack','age':12 }";
 2 JObject json = JObject.Parse(response);//json字符串转json
 3 IEnumerable<JProperty> property = json.Properties();//获取json的所有属性
 4 Console.WriteLine(json);
 5 foreach (var pro in property)
 6 {
 7     Console.WriteLine(pro.Name + "-->" + pro.Value);//遍历json属性 
 8 }
 9  
10 string arrayStr = "[{'name':'jack','age':12 }]";
11 JArray jArray = JArray.Parse(arrayStr);//json数组字符串转json数组
12  
13 DataTable dt = new DataTable();
14 dt = JsonConvert.DeserializeObject<DataTable>(jArray.ToString());
15  
16 string jsonStr = JsonConvert.SerializeObject(dt);//表格转json数组字符串
17 Console.WriteLine("1:" + jsonStr);
18  
19 string jsonStr2 = JsonConvert.SerializeObject(json);//json转json字符串
20 Console.WriteLine("2:" + jsonStr2);
21  
22 string jsonStr3 = JsonConvert.SerializeObject(jArray);//json数组转json数组字符串
23 Console.WriteLine("3:" + jsonStr3);
