小賴的實戰記錄

最近為了寫報表，製作了報表範本讀入函式。
將HTML的報表範本讀入後，利用Regular Expression將各個區段讀出來，在自己想辦法Replace組裝一下。
目前是劣質版，也就是以下這個Expression尚有問題，萬一範本中的文字中有@就會掛掉啦！（不知有何高招可以解決並讀入

<!--#ABC_START#-->我要的區段<!--#ABC_END#-->

string RegexExpression = "<!--[#]" + TemplateName + "_START[#]-->(?<item>[^@]+)<!--[#]" + TemplateName + "_END[#]-->";
