experiment : 使用WMI取本地计算机信息

最近的任务中有个分支任务, 要求将客户本地计算机Windows操作系统中的软硬件信息记录下来, 给研发看, 辅助调试用.

看到WMI能做这事, codeproject上资料还没有csdn上多~

有人反映WMI比较慢, 这对于我的任务倒没啥影响~, 在线程中执行, 界面上给个等待进度提示就可以.

参考:

整理了一个WMI Data 类, 以后复用. CWmiDataHelper用来连续执行SQL查询WMI中的内容. 还挺好用的~

只需要执行一个方法:

WmiData.ExecComQuery

取数据还是弄得挺丑, 得再想想. 实际取数据的时候, 要取多个数据. e.g. 取计算机逻辑分区信息分区No.1(分区盘符, 分区大小, 分区格式, 所在物理硬盘序列号)

以后有时间, 再整理一个取WMI逻辑数据的类, 此类调用CWmiDataHelper来工作.

此数据主要给研发看, 比如我自己, 看到测试程序的结果, 我也能明白.

剩下的就是工作量, 整的好看些. 如果有时间的话, 要精益求精的去提高用户体验, 假设用户就是我一个人, 也是如此.

计算机硬件检测程序, 一定也调用了WMI功能. 只是人家做的非常精细.

测试程序:
