EntityLoadInfo(ValueBuffer, Func<ValueBuffer,Object>)
初始化 EntityLoadInfo 结构的新实例。
public EntityLoadInfo (Microsoft.EntityFrameworkCore.Storage.ValueBuffer valueBuffer, Func<Microsoft.EntityFrameworkCore.Storage.ValueBuffer,object> materializer);new Microsoft.EntityFrameworkCore.Query.EntityLoadInfo : Microsoft.EntityFrameworkCore.Storage.ValueBuffer * Func<Microsoft.EntityFrameworkCore.Storage.ValueBuffer, obj> -> Microsoft.EntityFrameworkCore.Query.EntityLoadInfoPublic Sub New (valueBuffer As ValueBuffer, materializer As Func(Of ValueBuffer, Object))参数
- valueBuffer
- ValueBuffer
表示此实体的数据行。
- materializer
- Func<ValueBuffer,Object>
将数据具体化为实体实例的方法。
