1. Recently, the project has been launched, and after a few days of leisure, I want to repackage the serialization and deserialization of JSON and define it as JSONHelp, although Microsoft has done a good job. But I want to encapsulate a set of projects developed for my own use. It is convenient for later expansion and development.

two。 What is JSON?

JSON:JavaScript object representation (JavaScript Object Notation). JSON is the syntax for storing and exchanging text information. Similar to XML. JSON is smaller, faster and easier to parse than XML. Now it is essential to develop Web applications called JSON. JSON is a lightweight text data exchange case, JSON is language-independent, JSON is self-descriptive and easier to understand, JSON uses JavaScript syntax to describe data objects, but JSON is still independent of language and platform. JSON parsers and JSON libraries support many different programming languages.

3.JSON-convert to JavaScript object

The JSON text format is syntactically the same as the code that creates the JavaScript object. Because of this similarity, no parser is needed, and JavaScript programs can use the built-in eval () function to generate native JavaScript objects with JSON data.

4. Similar to XML

JSON is plain text JSON has the characteristic of self-description, JSON has a hierarchical structure (there are values in values) JSON can be parsed through JavaScript JSON data can be transmitted using AJAX compared to the difference of XML there is no closing tag shorter reading and writing speed can be parsed using the built-in, JavaScript eval () method, using arrays, without reserved words

5. Why use JSON?

For AJAX applications, JSON is faster and easier to use than XML: use XML to read XML documents, use XML DOM to loop through document read values and store them in variables

6. Use JSON

Read JSON strings use eval () to handle JSON string front-end JS interface We usually use JSON.parse () to serialize objects or strings into JSON and JSON.stringify () to serialize them into strings.

7. Serialization and deserialization of JSON

Serialization and deserialization of JSON I use JsonConvert.SerializeObject () in using Newtonsoft.Json and Jil.JSON.Serialize () in using System.Runtime.Serialization.Json;

Of course, the two serialization methods are the same. But Jil.JSON.Serialize () serialization is really much more efficient than this JsonConvert.SerializeObject (). It is obvious when a large amount of data is serialized. So

I strongly recommend using Jil.JSON.Serialize () to serialize and deserialize objects when the amount of serialization and deserialization data is very large and large.

The 9.JSONHelp.cs code is as follows:
