Configure automapper in asp net core 6

Introduction

Automapper is a popular library used in ASP.NET to simplify the mapping between different objects. It allows developers to mapping rules and automatically converts one object to another based on those rules. In this article, we will explore how to configure Automapper in ASP.NET Core 6.

Step 1: Install Automapper

The first step is to install the Automapper NuGet package. Open your ASP.NET Core 6 project in and navigate to the Package Manager Console. Run the following command to install Automapper:

Install-Package AutoMapper

Step 2: Create Mapping Profiles

Mapping profiles define the mapping rules between objects. Create a new folder in your project called “MappingProfiles” and add a new class file called “MyMappingProfile.cs”. In this file, define your mapping profiles as shown below:

In the above code, we create a new mapping rule between the “SourceObject” and “DestinationObject” classes. You can add more mapping rules based on your requirements.

Step 3: Configure Automapper

In your ASP.NET Core 6 application, open the “.cs” file. In the “ConfigureServices” method, add the following code to configure Automapper:

using AutoMapper;

public void ConfigureServices(IServiceCollection services)
{
    // Other service configurations
    
    services.AddAutoMapper(typeof(MyMappingProfile));
}

The above code registers the mapping profiles defined in the “MyMappingProfile” class with Automapper. Make sure to replace “MyMappingProfile” with the actual name of your mapping profile class.

Step 4: Use Automapper in Your Code

Now that Automapper is configured, you can use it in your code to object mapping. Here's an example:

In the above code, we the IMapper into our and use it to map the “SourceObject” to the “DestinationObject”. The object can then be used in our action method.

Conclusion

Configuring Automapper in ASP.NET Core 6 is a straightforward process. By following the steps outlined in this article, you can easily set up Automapper and use it to simplify object mapping in your ASP.NET Core 6 applications.
