Using newtonsoft. JSON;

Definition class:

Public class message
{
Public String address {Get; set ;}
[Jsonproperty (typenamehandling = typenamehandling. All)]
Public Object Body {Get; set ;}
}
Public class searchdetails
{
Public String query {Get; set ;}
Public String language {Get; set ;}
}

Test:

Message message = new message
{
Address = "http://google.com /",
Body = new searchdetails {query = "JSON. Net", language = "En-us "}
};
String jsonmsg = jsonconvert. serializeobject (message, formatting. indented); // indented indicates that the result is displayed in indentation.
System. Diagnostics. Debug. Write (jsonmsg );
Message deserialized = jsonconvert. deserializeobject <message> (jsonmsg );
Searchdetails = (searchdetails) deserialized. Body;
Response. Write (searchdetails. query + "," + searchdetails. Language + "<br/> ");

Debug output result format:

{
"Address": "http://google.com /",
"Body ":{
"$ Type": "testjsonserialization. searchdetails, testjsonserialization ",
"Query": "JSON. Net ",
"Language": "En-us"
}
}

Note: 1. The jsonproperty tag is used to control the serialization of a field or attribute as a JSON object.
