        static void Main(string[] args)
        {
            char symbol = 'a';
            Console.WriteLine("The code of {0} is: {1}", symbol, (int) symbol); //97
            symbol = 'A';
            Console.WriteLine("The code of {0} is: {1}", symbol, (int)symbol); //65

            symbol = 'щ';
            Console.WriteLine("The code of {0} is: {1}", symbol, (int)symbol); //1097

            symbol = '\u0061'; //   unicode symbol

       }
    }
}

Тип string

• Пример 2:

               string quotation =@"""Hello, Jude"", he said."

               string path=@"C:\WINNT\Darts\Darts.exe";

Обектен тип - object

{
    class Program
    {
        static void Main(string[] args)
        {
            object dataContainer = 5;
            Console.Write("The value of dataContaner is: ");
            Console.WriteLine(dataContainer);

            dataContainer = "Five";
            Console.Write("The value of dataContaner is: ");
