C parses an JSON instance

This article describes the C# method of parsing JSON as an example. C# encapsulates the class library for parsing XML and JSON, which is quite convenient to use! Specific usage is as follows:

1. Main classes used:

Mainly use the JavaScriptSerializer class, the class in System Web. Script. Serialization namespace (in System. Web. Extensions. dll), need to take. NET version is modified to. NET Framework 4 (default is. NET Framework 4 Client Profile) can in Add Reference of NET in reference to.

2. For example

. Assume that the JSON file format to be parsed is as follows (other formats can be processed accordingly)

{ 
  "key":1, 
  "value":"hello" 
} 

. Define the corresponding class

public class JsonObject 
{ 
  public string Key { get; set; } 
  public string Value{ get; set; } 
} 

. Then define the JavaScriptSerializer object, and call the Deserialize method of the object to resolve JSON to the JsonObject object defined above

var serializer = new JavaScriptSerializer(); 
var ret = serializer.Deserialize<JsonObject>(json); 
string key = ret.Key; 
string value = ret.Value;
