AutoMapper is a popular object-to-object mapping library that can be used to map objects belonging to dissimilar types. As an example, you might need to map the DTOs (Data Transfer Objects) in your application to the model objects.In this regard, why do we use AutoMapper?
AutoMapper is an object-object mapper which allows you to solve the problem of manually mapping each property of a class with the same properties of another class. Before AutoMapper was introduced if we wanted to assign one object property to another object property then we were following a long procedure.
Similarly, how does AutoMapper work in C#? The AutoMapper in C# is a mapper between two objects. That is AutoMapper is an object-object mapper. It maps the properties of two different objects by transforming the input object of one type to the output object of another type.
Also Know, should I use AutoMapper?
LINQ query extensions have the best performance of any mapping strategy, so it's better to use it as much as you can. If you have to do complex mapping behavior, it might be better to avoid using AutoMapper for that scenario. AutoMapper should not perform any business logic, only mapping configuration.
Does AutoMapper use reflection?
When you call CreateMap, AutoMapper uses optimizers to build the code for getting/setting values on source/destination types. Currently, it uses a combination of Reflection. Emit and expression tree compilation. At Map time, it uses the optimized callbacks for interacting with types.
Where is AutoMapper configuration?
ΒΆ Configuration should only happen once per AppDomain. That means the best place to put the configuration code is in application startup, such as the Global. asax file for ASP.NET applications.What is AutoMapper in C#?
AutoMapper is a popular object-to-object mapping library that can be used to map objects belonging to dissimilar types. As an example, you might need to map the DTOs (Data Transfer Objects) in your application to the model objects.What are DTOs in C#?
DTO (Data Transfer objects) is a data container for moving data between layers. They are also termed as transfer objects. DTO is only used to pass data and does not contain any business logic. They only have simple setters and getters. For example, below is an Entity class or a business class.What is Mapper class in C#?
"AutoMapper is an object-object mapper which allows you to solve the problem of manually mapping each property of a class with the same properties of another class.".What is Mapper MVC?
AutoMapper is an external component that helps in creating a mapping between a source and destination model types. Once the mapping is created then the source model object can be converted to a destination model object with ease and with less cluttered code.
