C # Read and write JSON

There are two main ways in which C # handles JSON files:

　　(1) using the JavaScriptSerializer class , you need to introduce a System.Web.Extension library and add the following two references:

Using System.Web;
Using System.Web.Script.Serialization;

The main code is as follows:

     Public classData { Public intId {Get;Set; } //[Scriptignore]         Public stringName {Get;Set; }  Public stringGetName () {returnId.tostring () +Name; }    }     Public classJsonpaserweb {//Object->json         Public stringSerialize (Data obj) {javascriptserializer Jsonserializer=NewJavaScriptSerializer (); stringJSON =jsonserializer.serialize (obj); returnJSON; }        //Json->object         PublicData Deserialize (stringJSON) {JavaScriptSerializer Jsonserializer=NewJavaScriptSerializer (); //Performing deserializationData obj = jsonserializer.deserialize<data>(JSON); returnobj; }    }

You can use the [Scriptignore] tag to make a variable not participate in serialization.

　　(2) using the DataContractJsonSerializer class , you need to introduce the System.Runtime.Serialization library and add the following references:

Using System.Runtime.Serialization;
Using System.Runtime.Serialization.Json;

The sample code looks like this:

[DataContract] Public classData {[DataMember (Name="ID", Order =0)]         Public intId; [DataMember (Name="name", Order =1)]         Public stringName; [DataMember (Name=" Child", Order =2)]         PublicChild child =NewChild (); [DataMember (Name="List", Order =3)]         Publiclist<int> Ids =Newlist<int>(); [DataMember (Name="Dictionary", Order =4)]         Publicdictionary<int, child> dic =Newdictionary<int, child>(); [Ignoredatamember] Public stringDescription ="This is a JSON data class"; }     Public classChild { Public floatAge ;  Public stringFullName; }    classJsonparserruntime {//Object->json         Public stringSerialize (Data obj) {datacontractjsonserializer Jsonserializer=NewDataContractJsonSerializer (obj.            GetType ()); stringJSON =""; using(MemoryStream stream =NewMemoryStream ())                {Jsonserializer.writeobject (stream, obj); JSON=Encoding.UTF8.GetString (stream.            ToArray ()); }            returnJSON; }        //Json->object         PublicData Deserialize (stringJSON) {Data obj=NULL; using(MemoryStream ms =NewMemoryStream (Encoding.UTF8.GetBytes (JSON))) {DataContractJsonSerializer Jsonserializer=NewDataContractJsonSerializer (typeof(Data)); Obj=(Data) Jsonserializer.readobject (MS); }            returnobj; }    }

Classes marked with [DataContract] can use both [DataMember (Name = "id", Order = 0)] Tokens to handle variables, or you can use the [Ignoredatamember] tag to make a variable not participate in serialization.
