Dapper FastCRUD Delete Data

30% OFF - 9th Anniversary discount on Dapper Plus until December 15 with code: ZZZANNIVERSARY9

Deleting an entity is the easiest because it only requires a unique Id to identify the deleted entity. The Dapper.SimpleCRUD library provides Delete and DeleteList extension methods to delete existing data from the database.

The following example deletes a single record using the Delete method.

private static void DeleteSingleAuthor()
{
    using (IDbConnection db = new SqlConnection(ConnectionString))
    {
        db.Delete<Author>(new Author { Id = 4 });
    }
}

Let's call the above method and retrieve all the authors from the database, as shown below.

static void Main(string[] args)
{
    DeleteSingleAuthor();
    List<Author> authors = GetAllAuthors();

    foreach (var author in authors)
    {
        Console.WriteLine(author.FirstName + " " + author.LastName);
    }
}

Let's execute the above code, and you will see that the record which has Id = 4 is no longer available.
