ASP.NET MVC-数据库视图为DbSet吗？

Question

I'm having a hard time connecting to an existing view in the database. I've created the model and now I'm trying to add the DbSet to my existing context so I can query it.

I've tried the following, but every time I create a new EF migration, it tries to create the object as a table in the database.

public DbSet<SurveyResponse> SurveyResponses { get; set; }

I tried the same declaration as an IQueryable which seemed to stop the creation of the table, but when I tried to access context.SurveyResponses, SurveyResponses was showing no data.

Any ideas?

To stop EF creating the tables you can specify the ignore changes flag when adding a migration.

add-migration name -ignorechanges

Entity Framework treats the view mappings the same as table mappings.

Just remember not to update the view entity otherwise you will get an error!
