managing property names returned in json from web api

Question

I am currently working with ASP.NET web api where I return a Model object like following from my REST operation:

Product with properties: Name, Id, Description, etc.....

When this is converted to a JSON object, it outputs it with property names above.

To cut down the payload returned from the web api operation, is there any way I can change the properties in the JSON object like for example Desc for Description. I could change the Model object but the property names would not make sense then!

Solution 1

The easy way to do this is through a data contract. Here is an article, but basically, it involves two annotations on your model. It also allows you to ignore anything you don't want serialized.

[DataContract]
public class Foo {  //Your model class

   [DataMember(Name="bar-none")]  //This also allows you to use chars like '-'
   public string bar {get; set;}

   [IgnoreDataMember]  //Don't serialize this one
   public List<string> fuzz { get; set;}

}

Solution 2

You could also consider using http://automapper.org/ on the asp.net side to map your full objects, to more lightweight ones. Might be overkill for just one or two small objects, but if you have a bunch to do this can save you some time (free and open source to boot).

This was perfect for my purposes, which were the same as OP's.

You might also need to add a reference to System.Runtime.Serialization which isn't added by default. stackoverflow.com/questions/7401795/namespace-for-datacontra‌​ct
