.net 自动生成程序集版本号

参考：http://blog.163.com/china0359@yeah/blog/static/1217194362010577545938/

上述内容中，还有版本号设置规则等内容，感觉还不错。

版本号可以存放在AssemblyInfo.cs文件中，[assembly: AssemblyVersion("1.0.0.0")]可以修改为：[assembly: AssemblyVersion("1.0.0.*")]；4个数字分别为主版本、次版本、内部版本号、修订号。

前两个是对外发布用的，要手工修改；

内部版本号，是2000年1月1日到编译日期的天数；

内部修订号是当天从0点0分0秒到当前时间的毫秒数。

该文件中除了版本号外，还有产品名称、公司名称等信息。

using System.Diagnostics;//取文件版本号用

           ////Application.ProductVersion;//程序集版本号
            lbVer.Text = "版本号：" + GetAssembly(typeof(System.Reflection.AssemblyVersionAttribute));

除此以外，在项目-属性-发布中，有个发布版本，可以设置为“随每次发布自增自动递增修订号”，可以再点击“立即发布”后修改版本号，不过CS程序好像没什么发布的概念吧，谁对这个有方法可以说下，学习学习。
