string html文件模板全路径 = context.Server.MapPath("AddCalc1.htm");//得到文件的全路径
string content = System.IO.File.ReadAllText(html文件模板全路径);
//替换前两个单元格的值,保存原有的值
//这里每写一次:content就是一个html页面,但是由于浏览器的容错性,所以不会显示出错
// context.Response.Write(content);
//这里的context.Response.Write(content);,可以看出来每一步,它是如何替换的
content = content.Replace("@num1", num1);
// context.Response.Write(content);
content = content.Replace("@num2", num2);
// context.Response.Write(content);
content = content.Replace("@result", result);

生成的下面的html代码很明显是错误的,但是显示出来并没有问题,提现了浏览器的容错性:
先看看浏览器的容错性:
<script type='text/javascript'>alert('Hello everyOne Im Credream')</script><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
