使用c#开发mapserver之环境变量

拿到一套 csharp-mapscript 类库后，经常搞不清楚这套类库的版本。其实 csharp-mapscript 中提供了版本信息察看的方法。非常简单：

mapscript .MS_VERSION ;

mapscript 是 csharp-mapscript 里面的一个对象， MS_VERSION 是它的一个静态方法，不需要定义直接可以调用。

输出 mapscript .MS_VERSION 之后可以看到如下信息：

5.6.1

说明我当前使用的版本是5.4.1 。

同理，还可以通过mapscript 对象来获取很多mapserver 的配置信息。

public class mapscript
