服务器上没有安装excel的情况下导出excel文件的处理 c#下
早就想写这篇文章，今天终于有了点时间。。。分享一下。
首先那要把DocumentFormat.OpenXml这个dll文件导入到你的工程里。
DocumentFormat.OpenXml是什么文件，它在哪有？别着急。。。。
写这篇文章时http://msdn.microsoft.com/en-us/office/bb265236.aspx这个路径可以找到。
打开以上链接之后下载Open XML SDK 2.0 for Microsoft Office这个就是了。
下面这个代码是我五天的成果，从不知道什么是Open XML到导出文件成功。。。五天，是不是太久了。。。人比较笨，没办法了

以上代码，看不懂的请留言，今天时间有限我就不一一解释没个语句是什么意思了。
以后会好好整理一下。
