一、添加依赖
1、MongoDB.Driver
2、MongoDB.Bson
二、配置服务到StartUp.cs
public void ConfigureServices(IServiceCollection services) { //添加mongodb依赖 string mongoConnectionString = Configuration.GetSection("Mongo:ConnectionString").Value; services.AddSingleton(new MongoClient(mongoConnectionString)); }
三、添加配置到appsettings.json
{ "Mongo": { "ConnectionString": "mongodb://账号:密码@服务器IP:27017/默认数据库名称" } }
四、自己编写的一个帮助类；这里只公布一部分。 其余的可以自行拓展
public class MongoBase<T>: IMongoBase<T> //接口可自己根据此类抽象出来 { private IMongoCollection<T> mongoClient; /// <summary> /// /// </summary> /// <param name="client"></param> /// <param name="name">MongoDB的表名</param> public MongoBase(MongoClient client, string name) { var database = client.GetDatabase("数据库名称"); mongoClient = database.GetCollection<T>(name); } #region 新增单个 + void InsertOne(T entity) /// <summary> /// 新增单个 /// </summary> /// <param name="entity"></param> public void InsertOne(T entity) { mongoClient.InsertOne(entity); } #endregion #region 批量新增 + void InsertMany(IEnumerable<T> entity) /// <summary> /// 批量新增 /// </summary> /// <param name="entity"></param> public void InsertMany(IEnumerable<T> entity) { mongoClient.InsertMany(entity); } #endregion #region 查找第一个 + T FindFirst(FilterDefinition<T> filter,FindOptions option = null) /// <summary> /// 查找第一个 /// </summary> /// <param name="filter"></param> /// <param name="option"></param> /// <returns></returns> public T FindFirst(FilterDefinition<T> filter, FindOptions option = null) { return mongoClient.Find(filter, option).FirstOrDefault(); } #endregion #region 查找多个 + List<T> FindList(FilterDefinition<T> filter, FindOptions option = null) /// <summary> /// 查找多个 /// </summary> /// <param name="filter"></param> /// <param name="option"></param> /// <returns></returns> public List<T> FindList(FilterDefinition<T> filter, FindOptions option = null) { return mongoClient.Find(filter, option).ToList(); } #endregion }
五、编写一个MongoDB集合
这里使用一个叫UserInfo的MongoDB数据库集合做测试
public class UserInfoService : MongoBase<UserInfo> { public UserInfoService(MongoClient client) : base(client, "UserInfo") { } }
六、在Controller中使用
public class MongoController : Controller { private UserInfoService userInfo; //使用DI注入； public MongoController(UserInfoService _userInfo) { this.userInfo = _userInfo; } public IActionResult Index() { UserInfo user = userInfo.FindFirst(Builders<UserInfo>.Filter.Eq(p => p.Name, "Test")); userInfo.InsertOne(new UserInfo() { Name="Test", UserID=222 }); user = userInfo.FindFirst(Builders<UserInfo>.Filter.Eq(p => p.Name, "Test")); return View(); } }
