求能不能实现输入多个汉字后转换成汉字区位码呢？代码是单个汉字的~

  private string strCode(char charOne)
  {
  Encoding unicode = Encoding.Unicode;
  Encoding gb2312 = Encoding.GetEncoding(936);
  byte[] unicodeBytes = unicode.GetBytes(new Char[] { charOne });
  byte[] asciiBytes = Encoding.Convert(unicode, gb2312, unicodeBytes);
  int n = (int)asciiBytes[0] << 8;
  n += (int)asciiBytes[1];
  return n.ToString();
  }

------解决方案--------------------

C# code

string str = "斯拉夫登陆了";
StringBuilder sb = new StringBuilder();
foreach(char c in str)
{
    sb.Append(strCode(c));
}
Console.WriteLine(sb.ToString());
