DbEntityEntry: Get Table Name (Code-First)

The table name may be acquired using the IObjectContextAdapter, as was mentioned in another response.

 private string GetTableName(DbEntityEntry ent)
        {
            ObjectContext objectContext = ((IObjectContextAdapter) this).ObjectContext;
            Type entityType = ent.Entity.GetType();

            if (entityType.BaseType != null && entityType.Namespace == "System.Data.Entity.DynamicProxies")
                entityType = entityType.BaseType;

            string entityTypeName = entityType.Name;

            EntityContainer container =
                objectContext.MetadataWorkspace.GetEntityContainer(objectContext.DefaultContainerName, DataSpace.CSpace);
            string entitySetName = (from meta in container.BaseEntitySets
                                    where meta.ElementType.Name == entityTypeName
                                    select meta.Name).First();
            return entitySetName;
        }

The code mentioned above also checks for proxies. Assuming the original poster has found the solution long ago, I hope this helps everyone else who visits this page.
