How to get the size of data types in C#

Answer 1

using System;

namespace ConsoleApplication_C_Sharp
{
    class Program
    {
        static void Main(string[] args)
        {
            int size = sizeof(byte);
            Console.WriteLine(size); // 1

            size = sizeof(int);
            Console.WriteLine(size); // 4

            size  = sizeof(Int16); // short // 2
            Console.WriteLine(size);

            size = sizeof(Int32); // int // 4
            Console.WriteLine(size);

            size = sizeof(Int64); // long // 8
            Console.WriteLine(size);

            size = sizeof(char);
            Console.WriteLine(size); // 2

            size = sizeof(bool);
            Console.WriteLine(size); // 1

            size = sizeof(double);
            Console.WriteLine(size); // 8           

            size = sizeof(decimal);
            Console.WriteLine(size); // 16
        }
    }
}
