c#中string字符串转为json对象
string转json
//字符串转json
public static void strJson()
{
json转换对象
string jsonText = "{"shenzheng":"深圳","beijing":"北京","shanghai":[{"zj1":"zj11","zj2":"zj22"},"zjs"]}";
JObject jo = (JObject)JsonConvert.DeserializeObject(jsonText);//或者JObject jo = JObject.Parse(jsonText);
string zone = jo["shenzheng"].ToString();//输出 "深圳"
string zone_en = jo["shanghai"].ToString();//输出 "[{"zj1":"zj11","zj2":"zj22"},"zjs"]"
string zj1 = jo["shanghai"][1].ToString();//输出 "zjs"
Console.WriteLine(jo);
}
对象与数组转JSON
//对象与数组转JSON
public static void GetJsonString()
{
//初始化对象
Obj product = new Obj() { Name = "苹果", Price = 5.5 };
//序列化
string o = new JavaScriptSerializer().Serialize(product);//值："{\"Name\":\"苹果\",\"Price\":5.5}"
//数组转json
List<Obj> products = new List<Obj>(){
new Obj(){Name="苹果",Price=5.5},
new Obj(){Name="橘⼦",Price=2.5},
new Obj(){Name="⼲柿⼦",Price=16.00}
};
ProductList productlist = new ProductList();
productlist.GetProducts = products;
//序列化
string os = new JavaScriptSerializer().Serialize(productlist);
//输出 "{\"GetProducts\":[{\"Name\":\"苹果\",\"Price\":5.5},{\"Name\":\"橘⼦\",\"Price\":2.5},{\"Name\":\"⼲柿⼦\",\"Price\":16}]}"    }
json转对象、数组, 反序列化
//json转对象、数组, 反序列化
public static void JSONStringToList()
{
//json格式字符串
string JsonStr ="{Name:'苹果',Price:5.5}";
JavaScriptSerializer Serializer =new JavaScriptSerializer();
//json字符串转为对象, 反序列化
Obj obj = Serializer.Deserialize<Obj>(JsonStr);
Console.Write(obj.Name +":"+ obj.Price +"\r\n");
//json格式字符串
string JsonStrs ="[{Name:'苹果',Price:5.5},{Name:'橘⼦',Price:2.5},{Name:'柿⼦',Price:16}]";        JavaScriptSerializer Serializers =new JavaScriptSerializer();
//json字符串转为数组对象, 反序列化
List<Obj> objs = Serializers.Deserialize<List<Obj>>(JsonStrs);
foreach(var item in objs)
{
Console.Write(item.Name +":"+ item.Price +"\r\n");
}
}
