DecimalAttribute for EntityFramework Core

NuGet Package

What's this?

This class library for Entity Framework Core on .NET Core/.NET Framework provides the ability for you to control the precision and scale of decimal column type, by annotating properties of entity types, like this.

[Decimal(10, 5)] // <-- This!
public decimal Height { get; set; }

How to use?

  1. Add Toolbelt.EntityFrameworkCore.DecimalAttribute package to your project.
> dotnet add package Toolbelt.EntityFrameworkCore.DecimalAttribute

Supported Versions

EF Core version This package version
v.3.0 v.3.0
v.2.0, 2.1, 2.2 v.1.0.x
  1. Annotate your model with [Decimal(precision, scale)] attribute that lives in Toolbelt.ComponentModel.DataAnnotations.Schema namespace.
using Toolbelt.ComponentModel.DataAnnotations.Schema;

public class Person
{
    public int Id { get; set; }

    [Decimal(10, 5)] // <- Here!
    public decimal Height { get; set; }
}
  1. [Important] Override OnModelCreating() method of your DbContext class, and call BuildDecimalColumnTypeFromAnnotations() extension method which lives in Toolbelt.ComponentModel.DataAnnotations namespace.
using Microsoft.EntityFrameworkCore;
using Toolbelt.ComponentModel.DataAnnotations;

public class MyDbContext : DbContext
{
    ...
    // Override "OnModelCreating", ...
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        // .. and invoke "BuildDecimalColumnTypeFromAnnotations"!
        modelBuilder.BuildDecimalColumnTypeFromAnnotations();
    }
}

That's all!

BuildDecimalColumnTypeFromAnnotations() extension method scans the DbContext with .NET Reflection technology, and detects [Decimal] attributes, then build models related to decimal column type.

After doing that, decimal type columns in the database which created by EF Core, is configured with precisions and scales that are specified by [Decimal] attribute.
