FastORM 是一个高性能、零运行时反射的 .NET ORM 框架,利用 C# Source Generators 在编译时生成高效的 SQL 和 ADO.NET 执行代码。

核心特性

  • 🚀 极致性能:核心 SQL 生成和参数绑定逻辑在编译时完成,零运行时反射开销,AOT 友好。
  • 🧩 混合模式:支持运行时动态查询构建(Dynamic LINQ),在保持高性能的同时提供极大的灵活性。
  • 🔒 类型安全:基于标准的 LINQ 语法,编译时检查类型错误。
  • 📦 多数据库支持:内置支持 SQL Server, MySQL, PostgreSQL, SQLite。
  • ⚡ 异步优先:全链路 Async/Await 支持,高并发友好。
  • 🛠️ 丰富功能
    • 完整的 CRUD 支持(单条、批量)。
    • 支持 Join, GroupBy, Aggregation 等复杂查询。
    • 内置事务管理。

快速开始

1. 定义实体

using System.ComponentModel.DataAnnotations.Schema;

[Table("users")]
public class User
{
    public int Id { get; set; }
    public string Name { get; set; } = "";
    public int Age { get; set; }
}

2. 定义上下文

继承 FastDbContext 并定义数据集。

using FastORM;
using System.Linq;
using System.Data.Common;

public class MyDbContext : FastDbContext
{
    public MyDbContext(DbConnection connection, SqlDialect dialect) 
        : base(connection, dialect) { }

    // 定义数据集
    public IQueryable<User> Users => new FastOrmQueryable<User>(this, "users");
}

3. 使用示例

using Microsoft.Data.Sqlite;
using FastORM;

// 初始化连接和上下文
using var connection = new SqliteConnection("Data Source=:memory:");
await connection.OpenAsync();

var ctx = new MyDbContext(connection, SqlDialect.Sqlite);

// 建表 (自动生成建表语句)
await ctx.CreateTableAsync<User>();

// 1. 插入 (Insert)
await ctx.InsertAsync(new User { Id = 1, Name = "Alice", Age = 30 });

// 2. 查询 (Query)
var user = await ctx.Users.Where(u => u.Id == 1).FirstOrDefaultAsync();

// 3. 更新 (Update) - 实体更新
if (user != null)
{
    user.Age = 31;
    await ctx.UpdateAsync(user);
}

// 4. 批量操作 (Bulk)
var users = new[] 
{ 
    new User { Id = 2, Name = "Bob", Age = 25 }, 
    new User { Id = 3, Name = "Carol", Age = 35 },
    new User { Id = 4, Name = "Jackson", Age = 106 },
    new User { Id = 5, Name = "Unknown", Age = 0 }
};
await ctx.InsertAsync(users);

// 5. 条件更新 (Where Update) - 高效!
// 将所有年龄大于 100 的用户年龄重置为 100
await ctx.Users
    .Where(u => u.Age > 100)
    .UpdateAsync(u => u.Age = 100);

// 6. 条件删除 (Where Delete) - 高效!
// 删除所有名字为 "Unknown" 的用户
await ctx.Users
    .Where(u => u.Name == "Unknown")
    .DeleteAsync();

// 7. 动态查询 (Dynamic Query)
// 支持运行时变量和动态条件
int minAge = 18;
var activeUsers = await ctx.Users
    .Where(u => u.Age >= minAge && u.Name.StartsWith("A"))
    .ToListAsync();
