主题：【原创】【老兵开源】一个可以计算你写的帖子有多少字的程序 -- 老兵帅客

说明：

这个程序用于计算字符串的长度并显示在特定区域，这样用户可以随时知道帖子长度，并设法使其超过1分/3分的边界线。

由于西西河似乎没有上传附件的功能（至少我是没有找到），只好贴上全部源代码，请用户自行编译。

编译方法：本程序是用C#写成的，因此用户需要有.Net Framework（可以从微软网站下载）或者Visual Studio.Net。然后用户或者使用集成环境构造一个C# Windows Application，加入该源程序并编译；或者使用CSC来编译该源程序。

使用方法：启动编译后的程序，将用户关心的字符串（例如正在编辑的西西河帖子）拷入该程序的上面那个大框子，该程序的下面那个小框子将自动显示该字符串的长度。注意：在该程序中，一个汉字或者一个字符都只算一个字符。

下面是源程序：
