Parametr sifatida o'tish
Siz ExpandoObject klassining namunalarini parametr sifatida o'tkazishingiz mumkin. E'tibor bering, bu misollar C# da dinamik ob'ektlar va Visual Basic'da kech bog'langan ob'ektlar sifatida ko'rib chiqiladi. Bu shuni anglatadiki, sizda ob'ekt a'zolari uchun IntelliSense yo'q va mavjud bo'lmagan a'zolarni chaqirganingizda kompilyator xatolarini olmaysiz. Agar mavjud bo'lmagan a'zoga qo'ng'iroq qilsangiz, istisno sodir bo'ladi.
Quyidagi kod misolida xususiyatlar nomlari va qiymatlarini chop etish usulini qanday yaratishingiz va ishlatishingiz mumkinligi ko'rsatilgan.
class Program
{
static void Main(string[] args)
{
dynamic employee, manager;
employee = new ExpandoObject();
employee.Name = "John Smith";
employee.Age = 33;
manager = new ExpandoObject();
manager.Name = "Allison Brown";
manager.Age = 42;
manager.TeamSize = 10;
WritePerson(manager);
WritePerson(employee);
}
private static void WritePerson(dynamic person)
{
Console.WriteLine("{0} is {1} years old.",
person.Name, person.Age);
// The following statement causes an exception
// if you pass the employee object.
// Console.WriteLine("Manages {0} people", person.TeamSize);
}
}
// This code example produces the following output:
// John Smith is 33 years old.
// Allison Brown is 42 years old.
