    Deserialize a JSON string into a C# object and set custom values into a property of that object

    This week I had to deserialize a JSON string into a collection of C# objects. The class of these objects contained not only the properties that map directly to the JSON properties but also an extra property which I wanted to fill with values based on the values of other properties of the object.

For that we will have to declare the skipped properties by using the DoNotValidate method when we define the mapping (CreateMap) between the two objects:

    Use a custom function when mapping one property to another with Automapper

    Automapper is a handful tool for mapping the properties of two different type objects together. Such mappings are very common when you are dealing with a multi-tier architecture in your program. For example you want to map the entity object, which contains data from the database, with the UI-model object of your WebApi action.

    For basic mapping examples refer to the Automapper documentation. In this article we will consider the following advanced example:

    For that you need a mapping between two properties of different type and also a function that runs every time to do this transformation:
