> FreeSql 提供多种使用习惯，请根据实际情况选择团队合适的一种：
|
||
|
||
- 要么FreeSql，原始用法；
|
||
- 要么[FreeSql.Repository](https://github.com/2881099/FreeSql/wiki/Repository)，仓储+工作单元习惯；
|
||
- 要么[FreeSql.DbContext](https://github.com/2881099/FreeSql/wiki/DbContext)，有点像efcore的使用习惯；
|
||
- 要么[FreeSql.BaseEntity](https://github.com/2881099/FreeSql/tree/master/Examples/base_entity)，求简单使用这个；

## 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) //自动同步实体结构到数据库
|
||
.Build(); //请务必定义成 Singleton 单例模式
|
||
|
||
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<Tag> 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<Song> Songs { get; set; }
|
||
public ICollection<Tag> Tags { get; set; }
|
||
}
|
||
```
|
||
|
||
## Query
|
||
```csharp
|
||
//OneToOne、ManyToOne
|
||
fsql.Select<Tag>()
|
||
.Where(a => a.Parent.Parent.Name == "粤语")
|
||
.ToList();
|
||
|
||
//OneToMany
|
||
fsql.Select<Tag>()
|
||
.IncludeMany(a => a.Tags, then => then.Where(sub => sub.Name == "xxx"))
|
||
.ToList();
|
||
|
||
//ManyToMany
|
||
fsql.Select<Song>()
|
||
.Where(s => s.Tags.AsSelect().Any(t => t.Name == "国语"))
|
||
.IncludeMany(a => a.Tags, then => then.Where(sub => sub.Name == "xxx"))
|
||
.ToList();
|
||
|
||
//Other
|
||
fsql.Select<Xxx>()
|
||
.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.AsSelect().Any(t => t.Parent.Id == t.UserId))
|
||
.Count(out var total)
|
||
.Page(page, size)
|
||
.OrderByDescending(a => a.Id)
|
||
.ToList()
|
||
```

|
||
.ToList();
|
||
|
||
fsql.Select<Song>()
|

||
## Repository & UnitOfWork
|
||
> dotnet add package FreeSql.Repository
|
||
|
||
```csharp
|
||
using (var uow = fsql.CreateUnitOfWork()) {
|
||
var repo1 = uow.GetRepository<Song>();
|
||
var repo2 = uow.GetRepository<Tag>();
|
||
|
||
repo2.DbContextOptions.EnableAddOrUpdateNavigateList = true;
|
||
repo2.Insert(new Tag {
|
||
Name = "testaddsublist",
|
||
Tags = new[] {
|
||
new Tag { Name = "sub1" },
|
||
new Tag { Name = "sub2" },
|
||
new Tag {
|
||
Name = "sub3",
|
||
Tags = new[] {
|
||
new Tag { Name = "sub3_01" }
|
||
}
|
||
}
|
||
}
|
||
});
|
||
uow.Commit();
|
||
}
|
||
```
