Use Take method allows to fetch the first “n” number of elements from database using Entity Framework Core.
using EntityFrameworkCore_ConsoleApp.Models;
namespace EntityFrameworkCore_ConsoleApp
{
public class Program
{
static void Main(string[] args)
{
using (var databaseContext = new DatabaseContext())
{
var products = databaseContext.Products.Take(2).ToList();
products.ForEach(product =>
{
Console.WriteLine("Id: " + product.Id);
Console.WriteLine("Name: " + product.Name);
Console.WriteLine("Price: " + product.Price);
Console.WriteLine("Quantity: " + product.Quantity);
Console.WriteLine("Description: " + product.Description);
Console.WriteLine("Status: " + product.Status);
Console.WriteLine("Photo: " + product.Photo);
Console.WriteLine("Created: " + product.Created.ToString("dd/MM/yyyy"));
Console.WriteLine("Category Id: " + product.CategoryId);
Console.WriteLine("---------------------");
});
}
}
}
}
Output

You can use combination of Take method and Where method as below:
using EntityFrameworkCore_ConsoleApp.Models;
namespace EntityFrameworkCore_ConsoleApp
{
public class Program
{
static void Main(string[] args)
{
using (var databaseContext = new DatabaseContext())
{
var products = databaseContext.Products.Where(product => product.Status == true).Take(2).ToList();
products.ForEach(product =>
{
Console.WriteLine("Id: " + product.Id);
Console.WriteLine("Name: " + product.Name);
Console.WriteLine("Price: " + product.Price);
Console.WriteLine("Quantity: " + product.Quantity);
Console.WriteLine("Description: " + product.Description);
Console.WriteLine("Status: " + product.Status);
Console.WriteLine("Photo: " + product.Photo);
Console.WriteLine("Created: " + product.Created.ToString("dd/MM/yyyy"));
Console.WriteLine("Category Id: " + product.CategoryId);
Console.WriteLine("---------------------");
});
}
}
}
}
Output

You can use combination of Take method and Where method and OrderBy method as below:
using EntityFrameworkCore_ConsoleApp.Models;
namespace EntityFrameworkCore_ConsoleApp
{
public class Program
{
static void Main(string[] args)
{
using (var databaseContext = new DatabaseContext())
{
var products = databaseContext.Products.Where(product => product.Status == true).OrderByDescending(product => product.Price).Take(2).ToList();
products.ForEach(product =>
{
Console.WriteLine("Id: " + product.Id);
Console.WriteLine("Name: " + product.Name);
Console.WriteLine("Price: " + product.Price);
Console.WriteLine("Quantity: " + product.Quantity);
Console.WriteLine("Description: " + product.Description);
Console.WriteLine("Status: " + product.Status);
Console.WriteLine("Photo: " + product.Photo);
Console.WriteLine("Created: " + product.Created.ToString("dd/MM/yyyy"));
Console.WriteLine("Category Id: " + product.CategoryId);
Console.WriteLine("---------------------");
});
}
}
}
}
Output

You can use combination of Take method and Where method and OrderBy method and Select method as below:
using EntityFrameworkCore_ConsoleApp.Models;
namespace EntityFrameworkCore_ConsoleApp
{
public class Program
{
static void Main(string[] args)
{
using (var databaseContext = new DatabaseContext())
{
var products = databaseContext.Products.Where(product => product.Status == true).OrderByDescending(product => product.Price).Take(2).Select(product => new
{
Id = product.Id,
Name = product.Name,
Price = product.Price
}).ToList();
products.ForEach(product =>
{
Console.WriteLine("Id: " + product.Id);
Console.WriteLine("Name: " + product.Name);
Console.WriteLine("Price: " + product.Price);
Console.WriteLine("---------------------");
});
}
