> Please select a development mode:
- Use FreeSql, keep the original usage.
- Use [FreeSql.DbContext](https://github.com/dotnetcore/FreeSql/wiki/Repository), Repository + UnitOfWork.
- Use [FreeSql.BaseEntity](https://github.com/dotnetcore/FreeSql/tree/master/Examples/base_entity), Simple mode.
> Some open source projects that use FreeSql:
- [Zhontai.net Management System](https://github.com/zhontai/Admin.Core)
- [A simple CMS implemented by .NET8](https://github.com/luoyunchong/lin-cms-dotnetcore)
- [AIBPM workflow](https://github.com/leooneone/aibpm.plus)
- [NetAdmin A rapid development framework based on C#12/.NET9 and FreeSql](https://github.com/nsnail/NetAdmin)
## 🚀 Quick start
> dotnet add package FreeSql.Provider.Sqlite
```csharp
static IFreeSql fsql = new FreeSql.FreeSqlBuilder()
.UseConnectionString(FreeSql.DataType.Sqlite, @"Data Source=document.db")
.UseAutoSyncStructure(true) //automatically synchronize the entity structure to the database
.Build(); //be sure to define as singleton mode
class Song {
[Column(IsIdentity = true)]
public int Id { get; set; }
public string Title { get; set; }
public string Url { get; set; }
public DateTime CreateTime { get; set; }
public ICollection Tags { get; set; }
}
class Song_tag {
public int Song_id { get; set; }
public Song Song { get; set; }
public int Tag_id { get; set; }
public Tag Tag { get; set; }
}
class Tag {
[Column(IsIdentity = true)]
public int Id { get; set; }
public string Name { get; set; }
public int? Parent_id { get; set; }
public Tag Parent { get; set; }
public ICollection Songs { get; set; }
public ICollection Tags { get; set; }
}
```
### 🔎 Query
```csharp
//OneToOne、ManyToOne
fsql.Select().Where(a => a.Parent.Parent.Name == "English").ToList();
//OneToMany
fsql.Select().IncludeMany(a => a.Tags, then => then.Where(sub => sub.Name == "foo")).ToList();
//ManyToMany
fsql.Select()
.IncludeMany(a => a.Tags, then => then.Where(sub => sub.Name == "foo"))
.Where(s => s.Tags.Any(t => t.Name == "Chinese"))
.ToList();
//Other
fsql.Select()
.Where(a => a.IsDelete == 0)
.WhereIf(keyword != null, a => a.UserName.Contains(keyword))
.WhereIf(role_id > 0, a => a.RoleId == role_id)
.Where(a => a.Nodes.Any(t => t.Parent.Id == t.UserId))
.Count(out var total)
.Page(page, size)
.OrderByDescending(a => a.Id)
.ToList()
```
[More..](https://github.com/dotnetcore/FreeSql/wiki/%e6%9f%a5%e8%af%a2)
```csharp
fsql.Select().Where(a => new[] { 1, 2, 3 }.Contains(a.Id)).ToList();
fsql.Select().Where(a => a.CreateTime.Date == DateTime.Today).ToList();
fsql.Select().OrderBy(a => Guid.NewGuid()).Limit(10).ToList();
fsql.Select().ToList(a => new
{
a.Id,
Tags = fsql.Select().ToList(),
SongTags = fsql.Select().Where(b => b.TopicId == a.Id).ToList()
});
```

### 🚁 Repository
> dotnet add package FreeSql.Repository
```csharp
[Transactional]
public void Add() {
var repo = ioc.GetService>();
repo.DbContextOptions.EnableCascadeSave = true;
var item = new Tag {
Name = "testaddsublist",
Tags = new[] {
new Tag { Name = "sub1" },
new Tag { Name = "sub2" }
}
};
repo.Insert(item);
}
```
