Some open source projects that use FreeSql:
🚀 Quick start
dotnet add package FreeSql.Provider.Sqlite
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<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 //OneToOne、ManyToOne
fsql.Select<Tag>().Where(a => a.Parent.Parent.Name == "English").ToList();
//OneToMany
fsql.Select<Tag>().IncludeMany(a => a.Tags, then => then.Where(sub => sub.Name == "foo")).ToList();
//ManyToMany
fsql.Select<Song>()
.IncludeMany(a => a.Tags, then => then.Where(sub => sub.Name == "foo"))
.Where(s => s.Tags.Any(t => t.Name == "Chinese"))
.ToList();
//Other
fsql.Select<YourType>()
.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()
fsql.Select<Song>().Where(a => new[] { 1, 2, 3 }.Contains(a.Id)).ToList();
fsql.Select<Song>().Where(a => a.CreateTime.Date == DateTime.Today).ToList();
fsql.Select<Song>().OrderBy(a => Guid.NewGuid()).Limit(10).ToList();
fsql.Select<Song>().ToList(a => new
{
a.Id,
Tags = fsql.Select<Tag>().ToList(),
SongTags = fsql.Select<SongTag>().Where(b => b.TopicId == a.Id).ToList()
});
🚁 Repository
dotnet add package FreeSql.Repository
[Transactional]
public void Add() {
var repo = ioc.GetService<BaseRepository<Tag>>();
repo.DbContextOptions.EnableCascadeSave = true;
var item = new Tag {
Name = "testaddsublist",
Tags = new[] {
new Tag { Name = "sub1" },
new Tag { Name = "sub2" }
}
};
repo.Insert(item);
}
