How to get multiple tables using Entity Framework Core

Question

Aryan Kumar · Answer

To get multiple tables using Entity Framework Core, you can use the DbSet class. The class DbSet represents a collection of entities from a single table. You can load related entities from another table into the current entity using the include method.

For example, the following code gets all the customers and their orders in one LINQ call:

C#

var customers = context.Customers.Include(c => c.Orders);

This code will first loads all the customers from the Customers table. Then, load all the orders for each customer from the Orders table.

You can also use the Include method to load multiple related entities in one LINQ call. For example, the following code gets all the customers, their orders, and the products that they ordered in one LINQ call:

C#

var customers = context.Customers.Include(c => c.Orders).Include(c => c.Orders.Products);

This code will first loads all the customers from the Customers table. Then, load all the orders for each customer from the Orders table. Finally, all products ordered by each customer are loaded from the Products table.

Here are some other things to keep in mind when getting multiple tables using Entity Framework Core:

You can join tables in a LINQ query using the join operator.
You can use the Where operator to filter the query results.
You can use the OrderBy operator to sort the result of your query.
You can use the Take and Skip operators to paginate the query results.
