Encoding

见下代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Encoding
{
    class A
    {
        public string Mys = string.IsInterned("Hello");
    }


    class Program
    {
        static void Main(string[] args)
        {

            string[] sarr = new string[]{"a","我"};
            for (int i = 0; i < sarr.Length; i++)
            {
                string s = sarr[i];

                Console.WriteLine(System.Text.Encoding.ASCII.GetBytes(s).Length);
                Console.WriteLine(System.Text.Encoding.Unicode.GetBytes(s).Length);
                Console.WriteLine(System.Text.Encoding.Default.GetBytes(s).Length);
                Console.WriteLine(System.Text.Encoding.UTF7.GetBytes(s).Length);
                Console.WriteLine(System.Text.Encoding.UTF8.GetBytes(s).Length);
                Console.WriteLine(System.Text.Encoding.UTF32.GetBytes(s).Length);

                Console.WriteLine("-------------------------------------------------------");
            }

            Console.ReadLine();
        }
    }
}

结果：
