Cast System.Data.Linq.Table <T> 到自定义类

Question

I do a request on my sql table using Linq to SQL . I get a instance of System.Data.Linq.Table<Table>

I have also a class with some properties which corresponds to the properties of my table (The properties have the same name as the properties of my instance of System.Data.Linq.Table<Table> )

How to cast the System.Data.Linq.Table<Table> to a instance of my custom class ?

Without do Select(x => new CustomClass() { Id = x.Id, Name = x.Name ....}) and without (if possible) using Reflexion (it's so slow)

You can use AutoMapper to map your objects You can check the getting started page here https://github.com/AutoMapper/AutoMapper/wiki/Getting-started

Basically you'll setup a mapping between your Table and CustomClass classes

Mapper.Initialize(cfg => cfg.CreateMap<Table, CustomClass>());

Then you can map a Table instance to a CustomClass one

CustomClass myCustomClass= Mapper.Map<CustomClass>(table);
