Encoding encode = System.Text.Encoding.GetEncoding("GB2312");

StreamReader myStreamReader = new StreamReader(myStream, encode);

string strhtml = myStreamReader.ReadToEnd();

string stroutput = strhtml.Replace("$[Formitem0]$", "要替换的内容");

myStream.Seek(0, SeekOrigin.Begin);

sw.Write(stroutput);

sw.Flush();

sw.Close();
