一個簡單的小工具，主要用來獲取當期的電腦信息以及內存的使用情況。本來也沒想著寫這個玩意，還不如隨便下個相關的軟件好使，但是前一段時間為了追查系統(tǒng)卡頓的問題，所以就加上了一段統(tǒng)計內存的代碼，用來看看是否由這個引起的。 既然統(tǒng)計了內存相關的數(shù)據，干脆一不做二不休，又加了下CPU以及硬盤的使用情況統(tǒng)計。 統(tǒng)計的準確不準確我也不好說，因為我也不太能確定，暫且就做個參考值吧。或許使用很多大佬封裝過的第三方DLL會準確很多。 
下面工具中還展示了部分關于電腦的基本信息數(shù)據，這個在之前的時候應該是有發(fā)過，我只是單純的拿了過來（功能實現(xiàn)的多看著洋氣）。 主要還是使用windows WMI，雖然下列關于內存情況的統(tǒng)計沒用（但其實也可以統(tǒng)計到），因為我感覺這個方式可能稍微準確點。。。 實現(xiàn)功能： 開發(fā)環(huán)境： 開發(fā)工具：Visual Studio 2013 .NET Framework版本：4.5 實現(xiàn)代碼： public class SystemUtil { #region 內存
