Using dynamic in. net 4 to convert a json string into an object.

Added support for weak types in. net 4. It provides a way to exchange data with weak objects. We often encounter the scenario of converting a json string into an object, although we can use

JavaScriptSerializer orDataContractJsonSerializer

However, some corresponding entity classes are still required, which is very troublesome. I checked the information online and found another implementation method:

Usage:

 json =  j =  len = obj1 = j[ name = j[].name;

 

Note that the dynamic type is used here. Here, the power of the weak type is highlighted.

Let's look at the specific implementation class:

                                                  dynamic FromJson(=  JavaScriptConverter[] { = jss.Deserialize(jsonStr, ())     Deserialize(IDictionary<, > (dictionary ==   ArgumentNullException( (type == (    IDictionary<, > Serialize(   IEnumerable<Type> {   ReadOnlyCollection<Type>( List<Type>( Type[] { (  IDictionary<, > Dictionary { ;  DynamicJsonObject(IDictionary<, >.Dictionary =   TryGetMember(GetMemberBinder binder,  =  (result  IDictionary<, >=  DynamicJsonObject(result  IDictionary<, >  (result  ArrayList && (result  ArrayList)  IDictionary<, >=  List<DynamicJsonObject>((result  ArrayList).ToArray().Select(x =>  DynamicJsonObject(x  IDictionary<, >  (result =  List<>((result
