Original Readme​

note

AutoDto

This tool allows to auto create DTO model from BL model in compile time.

It supports different strategies for relations, such as ReplaceToIdProperty, AddIdProperty and ReplaceToDtoProperty

Setup​

To use AutoDto, first install the NuGet package:

dotnet add package AutoDto
  • Declare partial DTO type like public partial SomeDto {}
  • Add attribute [DtoFrom(typeof(SomeBlType))]
  • Build project

Full simple setup:

[DtoFrom(typeof(SomeBlType))]
public partial SomeDto {}

AutoDto tool will generate partial SomeDto class with all public properties from SomeBlType.

Relation Strategies​

Relation strategy means what to do with relation property during generating DTO.

Supported strategies:

  • None
  • ReplaceToIdProperty
  • AddIdProperty
  • ReplaceToDtoProperty

Usage​

Set strategy in [DtoFrom] attribute after BL type.

[DtoFrom(typeof(SomeBlType), RelationStrategy.AddIdProperty)]
public partial SomeDto {}

If not specified - RelationStrategy.None will be used

None​

DTO will have property on BL type

ReplaceToIdProperty​

If BL relation property has Id property: DTO will have only RelationPropNameId property of BL relation Id prop type. If BlType has relation with array or enumerable - generated name will be RelationPropNameIds

❗ If no Id found in relation entity - result will be same as with None strategy

AddIdProperty​

DTO will have relation type property and Id property is found

ReplaceToDtoProperty​

Try find DTO, generated for RelationType and replace to RelationTypeDto.

❗ If many DTOs exists for RelationType - use [MainDto] attribute to mark which one should be used in ReplaceToDtoProperty

Ignore properties​

To avoid some properties from BlType, use [DtoIgnore] attribute:

[DtoFrom(typeof(SomeBlType), RelationStrategy.AddIdProperty)]
[DtoIgnore(nameof(SomeBlType.PropName1), nameof(SomeBlType.PropName2))]
public partial SomeDto {}

Options​

Options can be set only in .editorconfig.

❗ All options are applied once, after first generator running (mostly after open project).

Generator running​

Generator is based on IIncrementalGenerator. Generator is running on every class declaration change event (on every change that affects class structure). To avoid performance issues, it is used debouncer for collecting all events to regenerate classes. By default debounce time is 500 ms. After some time debouncer will collect execution statistic and rebalance timer.

Any user can turn off debouncer, set initial time ets by setting options in .editorconfig.

Supported options:

  • auto_dto.debounce.enabled - true/false - use debounce or always run generation for every event
  • auto_dto.debounce.interval - int - in milliseconds - set initial debounce interval
  • auto_dto.debounce.auto_rebalance_enabled - true/false - allow auto timer change or not.

Default values:

  • auto_dto.debounce.enabled = true
  • auto_dto.debounce.interval = 500
  • auto_dto.debounce.auto_rebalance_enabled = true

⚠️ Debouncer can be turned off and switched to every request generating.

Logging​

Logger is disabled by default. If any issues with generator - enable logger, set folder path for logs and set logging level.

Supported options:

  • auto_dto.logger.folder_path - string - path to folder where logs will be generated
  • auto_dto.logger.enabled - true/false
  • auto_dto.logger.log_level - Serilog log levels. See LogEventLevel

Default values:

  • auto_dto.logger.folder_path = Try get value from build_property.projectdir. If cannot - Path.Combine(Environment.CurrentDirectory, "Logs") is using
  • auto_dto.logger.enabled = false
  • auto_dto.logger.log_level = Warning

How to use​

Example ( source csproj, source files )​

This is the CSharp Project that references AutoDTO

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net7.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="AutoDto" Version="2.1.0" />
  </ItemGroup>
    <PropertyGroup>
        <EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
        <CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
    </PropertyGroup>
</Project>

Generated Files​

Those are taken from $(BaseIntermediateOutputPath)\GX

namespace AutoDTODemo;

public partial class DepartmentDTO
{
public System.Int32 ID { get; set; }
public System.String Name { get; set; }
}
