Is AutoMapper a good idea?

Is AutoMapper a good idea?

AutoMapper is a great tool when used for simple conversions. When you start using more complex conversions, AutoMapper can be invaluable. For very simple conversions you could of course write your own conversion method, but why write something that somebody already has written?

Why is AutoMapper used?

Use AutoMapper to eliminate the need to write tedious boilerplate code when mapping objects in your application. AutoMapper is a popular object-to-object mapping library that can be used to map objects belonging to dissimilar types.

Is AutoMapper an Antipattern?

AutoMapper is: A convention-based object-object mapper in . NET. In itself, AutoMapper does not violate the principle of DDD. It is how you use it that possibly does.

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.

Is AutoMapper fast?

Automapper is considerably faster when mapping a List of objects on . NET Core (It’s still slower on full .

How do you implement AutoMapper?

First we need to get the AutoMapper from the Nuget package as shown below.

1. Let us say we have a class at entity layer as below,
2. We need to create a class i.e Employee.
3. We have another class called User class at UI Layer.
4. We want to map Employee class to a User class, by using Automapper we can map as below,

What can I use instead of AutoMapper?

How do I get rid of AutoMapper?

To disable automapping, use Windows PowerShell to remove full access permissions from the user for the mailbox, and then add back full access permissions to the user. When you add back full access permissions to the user, use the AutoMapping:$false parameter.

How do I ignore property in AutoMapper?

You can configure AutoMapper, that it will ignore some properties during copying. It can be usefull, for example, if you get some object from EntityFramework and want to create object copy for cache. We configure AutoMapper to ignore property B during copying.

What is reflection emit?

Reflection. Emit is a powerful namespace in which we can dynamically emit transient and persisting assemblies at runtime. Reflection. Emit produces a low-level, language-neutral MSIL. Normally, we create an assembly by saving its source code to disk and then compiling that source code.

When do you know that you need automapper?

Use of AutoMapper indicates systemic deficiencies in the project. If you find yourself needing it, stop and think about your design. You’ll always find a better, more readable, more maintainable and more bug-free design.

Why do I not get exception in automapper?

And if you have a bug in your mapping code you don’t get exception in the place where you could potentially expect it. Actually you don’t get any exception at all. I observed that AutoMapper is somehow swallowing exception that occurs during the mapping.

Why do we use DTO instead of automapper?

We still use AutoMapper on all of our projects, but with some caveats: DTO is a strict projection of the data model. That last one was key – LINQ projection is *much* faster than even in-memory hand-rolled mapping, since it’s SQL to DTO.

Which is better automapper or manual mapping in C #?

Manual mapping, on the other hand, the hinting is executed well before compile time. In cases where AutoMapper has no clue, you must configure the mapping with code and setting flags. If you’re going to bother doing all the setup and code work, you have to question how much it saves over manual mapping.
