有关myxls的编程

          MyXls是用C#开源项目，可以应用于asp.net 或者 .net应用程序上。它根据微软公开的Excle文档格式文件（BIFF），以二进制格式直接生成excel文档，支持Excel versions 97 - 2007. 。这意味着可以不用在服务器上安装office就能够以excle格式输出数据库中存储的数据了。这对于许多项目来说都是很有用的。

    目前MyXls已经实现了单元格（cell）的格式设置，包括文本颜色、文本大小、字体、单位格边框、底色、列宽、行高，合并单元格，多个sheet页等功能。
    目前MyXls还不支持在excel文档中生成对象（如、文本框、按钮等）。MyXls主页称即将实现对excel文件的读取功能，个人认为读取的功能的用处还不是很多。
