windows phone中解决html乱码问题

1.

private static string ConvertExtendedAscii(string html)
{
    StringBuilder sb = new StringBuilder();
    foreach (var c in html)
    {
      int charInt = Convert.ToInt32(c);
      if (charInt > 127)
         sb.AppendFormat(“&#{0};”, charInt);
      else
         sb.Append(c);
    }
    return sb.ToString();
}

2.引用XNA框架

StreamReader reader = new StreamReader(TitleContainer.OpenStream(“731999031.htm”), Encoding.GetEncoding(“unicode”));
