如何将这样的Unicode还原为原来的字符串！我在此深鞠一贡，表示感谢！！

如
윈도우 모바일 발표
应该用什莫方法。

[juqiang]

结果是："윈도우모바일발표"。楼主，韩文？
代码如下：
string s = "윈도우모바일발표";
s = s.Replace("&#","");
s = s.Replace(";"," ");
char[] c = new Char[1]{' '};
string[] r = s.Split(c);
byte[] b = new byte[r.Length*2-2];

for(int i=0;i<r.Length-1;i++)
{
b[2*i+0] = (byte)(Convert.ToInt32(r[i])%256);
b[2*i+1] = (byte)(Convert.ToInt32(r[i])/256);
}
string result = System.Text.Encoding.Unicode.GetString(b);
//result输出为：윈도우모바일발표

faint！因为html作了转换，所以又显示回去了。你自己到.net里面运行一下代码，即可看到了。
