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:
