Base Supplements C # Json and objects convert to and from each other

Method one. JavaScriptSerializer

Method Two. JsonConvert

Example:

WEB API Project

1. New Model:

Namespace WebApi
{
public class Product
{
public string Name {set; get;}
public string Price {set; get;}
}

public class ShoppingCart
{
public string Name {set; get;}
Public list<product> productlist {set; get;}
}
}

2. Serialization and deserialization tool classes

(1). Create a new tool class using the JavaScriptSerializer method Jsonhelper:

...

Using System.Web.Script.Serialization;

Namespace WebApi
{
public static Class Jsonhelper<t>
{
private static JavaScriptSerializer serializer = new JavaScriptSerializer ();
public static string Getjsonstr (T objectList)
{
Return serializer. Serialize (objectList);
}

public static list<t> getobjectlist<t> (String jsonstr)
{
List<t> OBJS = serializer. Deserialize<list<t>> (JSONSTR);
return OBJS;
}

public static T Getobj (String jsonstr)
{
Return serializer. Deserialize<t> (JSONSTR);
}
}
}

(1). Create a new tool class using the JsonConvert method Netjsonhelper:

...

Using Newtonsoft.json;

Namespace Webapi.common
{
public class Netjsonhelper<t>
{
public static string Getjsonstr (T obj)
{
return jsonconvert.serializeobject (obj);
}

public static T Getobj (String objjsonstr)
{
Return (T) jsonconvert.deserializeobject<t> (OBJJSONSTR);
}

public static list<t> Getobjs (String objsjsonstr)
{
Return (list<t>) jsonconvert.deserializeobject<list<t>> (OBJSJSONSTR);
}

}
}

3. New Controller Shoppingcontroller

public class Shoppingcontroller:apicontroller
{

private static ShoppingCart ShoppingCart = new ShoppingCart ();
private static string productsstr = String. Empty; Save serialized string
Public Shoppingcontroller ()
{
list<product> products = new list<product> () {
New Product () {name= "Apple", price= "$20/kg"},
New Product () {name= "Banana", price= "$15/kg"},
New Product () {name= "melon", price= "$20/kg"}
};
Shoppingcart.name = "Myfruitbaskit";
Shoppingcart.productlist = Products;
}

public string Getshoppingcart ()
{
String jsonstr = jsonhelper<shoppingcart>. Getjsonstr (ShoppingCart);
PRODUCTSSTR=JSONSTR; Saves the serialized string for deserialization of the interface test
return jsonstr;
}

Public ienumerable<product> getfruitlist ()
{
ShoppingCart shoppingcartobj = jsonhelper<shoppingcart>. Getobj (PRODUCTSSTR);
return shoppingcartobj.productlist;
}

public string Getshoppingcartbynetjson ()
{
String jsonstr = netjsonhelper<shoppingcart>. Getjsonstr (ShoppingCart);
Productsstr = Jsonstr; Saves the serialized string for deserialization of the interface test
return jsonstr;
}

Public ienumerable<product> Getfruitlistbynetjson ()
{
ShoppingCart shoppingcartobj = netjsonhelper<shoppingcart>. Getobj (PRODUCTSSTR);
return shoppingcartobj.productlist;
}

}

4. Start the Web API for testing

such as: Test JavaScriptSerializer

First: Localhost:xxxx/api/shopping/getshoppingcart

Then: localhost:xxxx/api/shopping/getfruitlist

Both methods do not have an exception when they are passed to null , regardless of whether they are serialized or deserialized
