The choice between eager and lazy loading depends on specific use cases and performance considerations. Eager loading is suitable when related data is consistently required together, optimizing performance by r
Lazy loading 中又使用Eager loading 如果在启用Lazy loading后又使用了Include方法来使用Eager loading,那么实际上是Eager loading在起作用,这样EF Core实体的导航属性不会再单独开启数据库连接去数据库查询数据,而是用sql语句的join预先在数据库中查询数据: 假设我们现在有Person实体里面有个Book导航属性,返回ICollection<...

1、FetchType.LAZY:懒加载,加载一个实体时,定义懒加载的属性不会马上从数据库中加载。 2、FetchType.EAGER:急加载,加载一个实体时,定义急加载的属性会立即从数据库中加载。 3、比方User类有两个属性,name跟address,就像百度知道,登录后用户名是需要显示出来的,此属性用到的几率极大,要马上到数据库查,用急加载;...
2. Lazy Loading 3. Explicit Loading and more How to choose loading pattern? Use Eager Loadingwhen the data in related entities is too costly to be loaded at the cost of the queries being made to the database. In other words, fetch all of them at once along with the main entity using...

In case of tracking queries, the navigation on which filtered include was applied is considered to be loaded. This means that EF Core will not attempt to re-load its values using explicit loading or lazy loading, even though some elements could still be missing.Include...
