c# - how to get a list of all entities in EF 5?

I am building an MVC 4 app. I have view that has a dropdown that needs to display all the tables (entities) used..

How can I do that? I am using EF 5 code first with configurations.

Any help would be appreciated.

Thanks

This code will get them for you, of course the ones that has been imported to your EDM which necessarily is not all the tables in your data store.

var tableNames = context.MetadataWorkspace.GetItems(DataSpace.SSpace)
                        .Select(t => t.Name)
                        .ToList();

For code first:

using System.Data.Metadata.Edm;
using System.Data.Objects;
using System.Data.Entity.Infrastructure;

...

using (dbcontext context = new TestContext())
{
   ObjectContext objContext = ((IObjectContextAdapter)context).ObjectContext;
   MetadataWorkspace workspace = objContext.MetadataWorkspace;
   IEnumerable<EntityType> tables = workspace.GetItems<EntityType>(DataSpace.SSpace);

}
