一个简单的小工具，主要用来获取当期的电脑信息以及内存的使用情况。本来也没想着写这个玩意，还不如随便下个相关的软件好使，但是前一段时间为了追查系统卡顿的问题，所以就加上了一段统计内存的代码，用来看看是否由这个引起的。 既然统计了内存相关的数据，干脆一不做二不休，又加了下CPU以及硬盘的使用情况统计。 统计的准确不准确我也不好说，因为我也不太能确定，暂且就做个参考值吧。或许使用很多大佬封装过的第三方DLL会准确很多。 
下面工具中还展示了部分关于电脑的基本信息数据，这个在之前的时候应该是有发过，我只是单纯的拿了过来（功能实现的多看着洋气）。 主要还是使用windows WMI，虽然下列关于内存情况的统计没用（但其实也可以统计到），因为我感觉这个方式可能稍微准确点。。。 实现功能： 开发环境： 开发工具：Visual Studio 2013 .NET Framework版本：4.5 实现代码： public class SystemUtil { #region 内存
