Dapper.FluentMap A Getting Started Tutorial for Mapping

Overview

Dapper.FluentMap is a small library that allows you to fluently map properties of your domain classes to the database columns. This library functionality is similar to Entity Framework Fluent API and keeps your domain classes clean of mapping attributes.

• It is straightforward to set up, just create a map class for each of your domain model and database model classes, and configure the mappings using the fluent API.
• Once you have done that, you can use Dapper.FluentMap to automatically map your classes to each other.
• By default, Dapper will map an object's properties to columns with the same name.
• However, sometimes you might want to map an object's properties to columns with different names.
• It allows you to configure these mappings in a fluent, concise way.

NuGet Installation

Dapper.FluentMap is available through NuGet: https://www.nuget.org/packages/Dapper.FluentMap/

You can easily install this library by running the following command:

PM> Install-Package Dapper.FluentMap

APIs

There are two types of mapping supported in Dapper.FluentMap.

• Manual mapping
• Convention-based mapping

You can map property names manually using the EntityMap<TEntity> class.

public class InvoiceMap : EntityMap<Invoice>
{
    public InvoiceMap()
    {
        // Map property 'InvoiceID' to column 'Id'.
        Map(i => i.InvoiceID).ToColumn("Id");

        // Ignore the 'Detail' and 'Items' properties when mapping.
        Map(i => i.Detail).Ignore();
        Map(i => i.Items).Ignore();
    }
}

Initialize your mapping at the start of your application.

FluentMapper.Initialize(config =>
{
    config.AddMap(new InvoiceMap());
});

Unfortunately, there is no proper documentation available for this library, but you can get a little bit of help from: https://github.com/henkmollema/Dapper-FluentMap
