If you are happy to have a dependency upon the System.Web.Helpers assembly, then you can use the Json class:
dynamic data = Json.Decode(json);It is included with the MVC framework as an additional download to the .NET 4 framework. Be sure to give Vlad an upvote if that‘s helpful! However if you cannot assume the client environment includes this DLL, then read on.
An alternative deserialisation approach is suggested here. I modified the code slightly to fix a bug and suit my coding style. All you need is this code and a reference to
System.Web.Extensions from your project:
You can use it like this:
string json = ...; var serializer = new JavaScriptSerializer(); serializer.RegisterConverters(new[] { new DynamicJsonConverter() }); dynamic obj = serializer.Deserialize(json, typeof(object));So, given a JSON string:
{ "Items":[ { "Name":"Apple", "Price":12.3 }, { "Name":"Grape", "Price":3.21 } ], "Date":"21/11/2010" }The following code will work at runtime:
dynamic data = serializer.Deserialize(json, typeof(object)); data.Date; // "21/11/2010" data.Items.Count; // 2 data.Items[0].Name; // "Apple" data.Items[0].Price; // 12.3 (as a decimal) data.Items[1].Name; // "Grape" data.Items[1].Price; // 3.21 (as a decimal)时间： 2024-11-03 01:38:28
