Use newtonsoft. JSON to convert, read, and write data in. net.

Using newtonsoft. JSON;
Using newtonsoft. JSON. converters;

// Deserializes a json string into an object
Target object = javascriptconvert. deserializeobject (JSON string, typeof (target object ));
// Serialize the target object into a JSON string

String JSON string = javascriptconvert. serializeobject (target object );

1. Reference newtonsoft. JSON. dll
2. Add reference in the project ..
Serialization and deserialization in the. Net project:

Product product = new Product();

product.Name = "Apple";

product.Expiry = new DateTime(2008, 12, 28);

product.Price = 3.99M;

product.Sizes = new string[] { "Small", "Medium", "Large" };

string output = JavaScriptConvert.SerializeObject(product);

//{

//  "Name": "Apple",

//  "Expiry": new Date(1230422400000),

//  "Price": 3.99,

//  "Sizes": [

//     "Small",

//     "Medium",

//     "Large"

//  ]

//}

Product deserializedProduct = (Product)JavaScriptConvert.DeserializeObject(output, typeof(Product));

Read JSON

string jsonText = "['JSON!',1,true,{property:'value'}]";

JsonReader reader = new JsonReader(new StringReader(jsonText));

Console.WriteLine("TokenType\t\tValueType\t\tValue");

while (reader.Read())

{

     Console.WriteLine(reader.TokenType + "\t\t" + WriteValue(reader.ValueType) + "\t\t" + WriteValue(reader.Value))

}

Result:

Tokentype	Valuetype	Value
Startarray	Null	Null
String	System. String	JSON!
Integer	System. int32	1
Boolean	System. Boolean	True
Startobject	Null	Null
Propertyname	System. String	Property
String	System. String	Value
Endobject	Null	Null
Endarray	Null	Null

JSON writing

StringWriter sw = new StringWriter();

JsonWriter writer = new JsonWriter(sw);

writer.WriteStartArray();

writer.WriteValue("JSON!");

writer.WriteValue(1);

writer.WriteValue(true);

writer.WriteStartObject();

writer.WritePropertyName("property");

writer.WriteValue("value");

writer.WriteEndObject();

writer.WriteEndArray();

writer.Flush();

string jsonText = sw.GetStringBuilder().ToString();

Console.WriteLine(jsonText);

// ['JSON!',1,true,{property:'value'}]
