Lage.AutoBuilder
🔧 基于 Roslyn 增量源生成器(IIncrementalGenerator)的编译期 Builder 模式自动代码生成器。
只需一个 [Buildable] 特性,自动为你的类生成 Builder 类,告别手写繁琐的建造者代码。
✨ 特性
| 特性 | 说明 |
|---|---|
[Buildable] |
标记目标类,自动生成 XxxBuilder |
[BuildIgnore] |
跳过某个属性,不出现在 Builder 中 |
[BuildMethod] |
指定静态工厂方法作为构建入口 |
CreateBuilder() |
目标类自动生成静态入口方法 |
global:: 全限定名 |
生成代码全部使用全限定名,零冲突 |
| 作用域一致 | Builder 可访问性与主类保持一致 |
📦 安装
dotnet add package Lage.AutoBuilder
编译要求:.NET 6.0 SDK 及以上 | 生成的代码兼容 .NET 5.0+ 运行时
🚀 快速开始
1. 标记类 + 属性
using Lage.AutoBuilder.Core.Attributes;
[Buildable]
public partial class Person
{
public string Name { get; set; } = null!;
public string Password { get; set; } = null!;
[BuildIgnore] // 该属性不出现在 Builder 中
public string InternalId { get; set; } = null!;
public int Age { get; set; }
public string? Email { get; set; }
}
2. 使用生成的 Builder
var person = Person.CreateBuilder()
.WithName("张三")
.WithPassword("abc123456")
.WithAge(28)
.WithEmail("zhangsan@example.com")
.Build();
3. 静态工厂方法 [BuildMethod]
[Buildable]
public partial class Order
{
public string Id { get; }
public decimal Amount { get; }
public DateTime CreatedAt { get; }
private Order(string id, decimal amount, DateTime createdAt)
{
Id = id;
Amount = amount;
CreatedAt = createdAt;
}
[BuildMethod]
public static Order Create(string id, decimal amount, DateTime createdAt)
=> new(id, amount, createdAt);
}
// 生成:
var order = Order.CreateBuilder()
.WithId("ORD-001")
.WithAmount(99.99m)
.WithCreatedAt(DateTime.Now)
.Build();
