C#漢字-區位碼相互轉化類

項目中需要對漢字使用區位碼進行轉化，寫了一個類，分享如下：

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

namespace Rare.Card.Libary.Helper
{
    public class CharacterAreaCodingConvertHelper
    {
        /// <summary>
        /// 漢字轉區位碼
        /// </summary>
        /// <param name="character"></param>
        /// <returns></returns>
        public static string CharacterToCoding(string character)
        {
            string coding = string.Empty;
            for (int i = 0; i < character.Length; i++)
            {
                byte[] bytes = System.Text.Encoding.GetEncoding("GB2312").GetBytes(character.Substring(i, 1));
                string lowCode = System.Convert.ToString(bytes[0], 16); //取出低位元組編碼內容（兩位16進位）
                if (lowCode.Length == 1)
                    lowCode = "0" + lowCode;
                string hightCode = System.Convert.ToString(bytes[1], 16);//取出高位元組編碼內容（兩位16進位）
                if (hightCode.Length == 1)
                    hightCode = "0" + hightCode;
                coding += (lowCode + hightCode);//加入到字串中,
            }
            return coding;
        }
        /// <summary>
        /// 區位碼取漢字
        /// </summary>
        /// <param name="coding"></param>
        /// <returns></returns>
        public static string CodingToCharacter(string coding)
        {
            string characters = string.Empty;
            if (coding.Length % 4 != 0)//編碼為16進位,必須為4的倍數。
            {
                throw new System.Exception("編碼格式不正確");
            }
            for (int i = 0; i < coding.Length / 4; i++)
            {
                byte[] bytes = new byte[2];
                int j = i * 4;
                string lowCode = coding.Substring(j, 2); //取出低位元組,並以16進位進位轉換
                bytes[0] = System.Convert.ToByte(lowCode, 16);
                string highCode = coding.Substring(j + 2, 2); //取出高位元組,並以16進位進行轉換
                bytes[1] = System.Convert.ToByte(highCode, 16);
                string character = System.Text.Encoding.GetEncoding("GB2312").GetString(bytes);
                characters += character;
            }
            return characters;
        }
    }
}

 

 

測試資料：

比如“布”
 查出來的是1828
 18－－－0x12 -----0x12+0xa0 = 0xB2
 28 ---- 0x1c + 0xA0 ------0xBC
 所以“布”的區位碼是B2Bc
字串：張三的區位碼轉化以後是D5C5C8FD
