Encoding encode = System.Text.Encoding.GetEncoding("GB2312");
StreamReader myStreamReader = new StreamReader(myStream, encode);
string strhtml = myStreamReader.ReadToEnd();
string stroutput = strhtml.Replace("$[Formitem0]$", "要替換的內容");
myStream.Seek(0, SeekOrigin.Begin);
myStream.SetLength(0);
StreamWriter sw = new StreamWriter(myStream, encode);
