TwoRivers.Dapper

Provides column mapping for Dapper. This allows you to map column names to properties on your classes without having to jump through hoops.

Installation

You can install the TwoRivers.Data.Dapper package via Package Manager Console:

Install-Package TwoRivers.Data.Dapper

Or via .NET CLI:

dotnet add package TwoRivers.Data.Dapper

Usage

Decorate your class with the [HasColumnMaps] attribute and then decorate the properties with the [ColumnName] attribute to map the column name to the property.

[HasColumnMaps]
public class Invoice
{
    [ColumnName("id")]
    public Int32 InvoiceNumber { get; set; }

    public required InvoiceLineItem[] LineItems { get; set; } = [];

    [ColumnName("customer_fk")]
    public Int32 CustomerId { get; set; }

    [ColumnName("site_number")]
    public Int32 SiteNumber { get; set; }
}

Before your first query, use one or more of the following to apply the column maps:

ColumnMapper.MapTypesFromCallingAssembly();

ColumnMapper.MapTypesFromExecutingAssembly();

ColumnMapper.MapTypesFromAssemblyContaining<Invoice>();

ColumnMapper.MapTypesFromAssemblies(typeof(Invoice).Assembly);

Or map specific types:

ColumnMapper.Map<Invoice>();

typeof(Invoice).MapColumns();

NOTE: If you are mapping specific types, you do not need to apply the [HasColumnMaps] attribute to the class.

That's it! You are done! Dapper will now use the column mappings when a query returns a type that has been mapped.
