Basic LINQ queries

This book is not intended to be a LINQ handbook. However, we will show you some basic LINQ queries in this section:

  • Querying the data
  • Filtering the data
  • Sorting the data
  • Paging the data
  • Creating the data
  • Updating the data
  • Deleting the data

Querying the data

The DbSet<Invoice> Invoices property in the InvoiceDbContext class represents a collection of the Invoice entity. We can use LINQ methods to query the data. For example, we can use the ToListAsync() method to retrieve all the invoices from the database:

var invoices = await _context.Invoices.ToListAsync();

That is how the GetInvoices action method works.

To find a specific invoice, we can use the FindAsync() method, as shown in the GetInvoice() action method:

var invoice = await _context.Invoices.FindAsync(id);

The FindAsync() method accepts the primary key value as the parameter. EF Core will translate the FindAsync() method to the SQL SELECT statement...
