DotNet中获取系统信息（一）

happmaoo

前几天发了一张用C#获取系统信息的随笔，得到很多高人的指点，获益良多啊！
这两天又抽空重构了一下，使用了singleton模式，并支持读取多CPU和多网卡的信息（未使用WMI），但没办法测试，不知道行不行！请高手指导！
全过程都使用了TestDriver.NET（以前叫NUnitAddin）和ReSharper1.0，确实不错。尤其是ReSharper，重构功能比Togetherfor vs.net 2.0的好用多了，其它功能也不错（所以抛弃了VAX和CodeRush，多了太耗资源）。
代码较多，先发主要的：SystemInfomation.cs
