SQL so'rovlar orqali ma'lumotlar bazalari bilan ishlash tajribangiz bormi?

Ha, SQL so'rovlar orqali ma'lumotlar bazalari bilan o'zaro aloqalar C# dasturlashda standart amaliyot hisoblanadi. Odatda ADO.NET yoki ORM, masalan, Entity Framework ishlatiladi.

ADO.NET yordamida oddiy SQL so'rovi misoli:

using System.Data.SqlClient;

string connectionString = "Server=myServer;Database=myDB;User Id=myUser;Password=myPass;";
string query = "SELECT Id, Name FROM Users WHERE Age > @age";

using (SqlConnection connection = new SqlConnection(connectionString))
{
    SqlCommand command = new SqlCommand(query, connection);
    command.Parameters.AddWithValue("@age", 18);

    connection.Open();
    using (SqlDataReader reader = command.ExecuteReader())
    {
        while (reader.Read())
        {
            int id = reader.GetInt32(0);
            string name = reader.GetString(1);
            Console.WriteLine($"User: {id}, {name}");
        }
    }
}

Bu yondashuv har qanday SQL so'rovlarini bajarishga, ma'lumotlarni olishga va ular bilan ishlashga imkon beradi.
