Please select a development mode:
- Use FreeSql, keep the original usage.
- Use FreeSql.DbContext, Repository + UnitOfWork.
- Use FreeSql.BaseEntity, Simple mode.
Some open source projects that use FreeSql:
- Zhontai.net Management System
- A simple CMS implemented by .NET8
- AIBPM workflow
- NetAdmin A rapid development framework based on C#12/.NET9 and 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 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
//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()
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
[Transactional] public void Add() { var repo = ioc.GetService<BaseRepository>(); repo.DbContextOptions.EnableCascadeSave = true;
var item = new Tag { Name = "testaddsublist", Tags = new[] { new Tag { Name = "sub1" }, new Tag { Name = "sub2" } } }; repo.Insert(item); }
