求一段小程序
A0B3883EC4E9上面的字符串是unicode的编码
我想把它还原成ascii，怎么实现？
3x --------------------编程问答-------------------- 程序在FressBSD/Linux上调试通过，Windows 用户只要修改几个变量类型和头文件即可
说明：函数名称
int strUnicode2GB(char *strSourcer, char *strDest,int n)
转换Unicde字符串到GB码，返回汉字数
输入( Unicode 源串，GB2312/ASCII混合编码串,Unicode字节数 必须是偶数!!!)
[code:1:0a0b72ed53]
#include <sys/types.h>
const unsigned short int Unicode_GB2312[][2] =
{
/*Unicode ,GB||ASCII ,MEMO*/
0x0000,0x0040,/* 0 COMMERCIAL AT @ */
0x0001,0x00A3,/* 1 POUND SIGN ￡ */
0x0002,0x0024,/* 2 DOLLAR SIGN $ */
0x0003,0x00A5,/* 3 YEN SIGN ￥ */
0x0004,0x00E8,/* 4 LATIN SMALL LETTER E WITH GRAVE è */

码表太长了 请尽量通过 Google 查询.

--------------------编程问答-------------------- 以上为c++实现。 --------------------编程问答-------------------- byte[] bts = { 0xA0, 0xB3, 0x88, 0x3E, 0xC4, 0xE9 };
？？ --------------------编程问答--------------------
using System;--------------------编程问答-------------------- C# 现成的方法就可以用 --------------------编程问答-------------------- C#下有 Encoding 函数使用 --------------------编程问答-------------------- 谢谢谢谢，等我过年的时候 测试以下，再结帖：）
using System.Text;
namespace ConvertExample
{
class ConvertExampleClass
{
static void Main()
{
string unicodeString = "This string contains the unicode character Pi(\u03a0)";
// Create two different encodings.
Encoding ascii = Encoding.ASCII;
Encoding unicode = Encoding.Unicode;
// Convert the string into a byte[].
byte[] unicodeBytes = unicode.GetBytes(unicodeString);
// Perform the conversion from one encoding to the other.
byte[] asciiBytes = Encoding.Convert(unicode, ascii, unicodeBytes);
// Convert the new byte[] into a char[] and then into a string.
// This is a slightly different approach to converting to illustrate
// the use of GetCharCount/GetChars.
char[] asciiChars = new char[ascii.GetCharCount(asciiBytes, 0, asciiBytes.Length)];
ascii.GetChars(asciiBytes, 0, asciiBytes.Length, asciiChars, 0);
string asciiString = new string(asciiChars);
// Display the strings created before and after the conversion.
Console.WriteLine("Original string: {0}", unicodeString);
Console.WriteLine("Ascii converted string: {0}", asciiString);
}
}
}
补充：.NET技术 , C#
