回憶剛進(jìn)公司那會(huì )兒，手頭的第一個(gè)工作就是完成虛擬鍵盤(pán)，也就是通過(guò)驅動(dòng)程序向鍵盤(pán)端口寫(xiě)入數據，
這份活至今記憶猶新，那會(huì )兒寫(xiě)的是個(gè)過(guò)濾驅動(dòng)程序，也就是將我的虛擬設備綁定到真實(shí)的鍵盤(pán)設備上，
當驅動(dòng)程序編譯完成以后，我也總是通過(guò)下面的這個(gè)工具來(lái)安裝驅動(dòng)程序，
每編譯好一次就使用這個(gè)工具重新安裝驅動(dòng)一次，然后通過(guò) DbgView 來(lái)打印消息，
那會(huì )兒還真傻，為了弄出這么個(gè)虛擬鍵盤(pán)，都不曉得安裝了驅動(dòng)多少回，
直到后來(lái)，當驅動(dòng)程序完成以后，就需要部署驅動(dòng)程序了，在網(wǎng)上找了很多資料，
大部分也都是通過(guò) INF 文件來(lái)實(shí)現，而對于 WDM 驅動(dòng)程序，則還可以通過(guò)服務(wù)控制臺來(lái)實(shí)現安裝，
模模糊糊還記得當初就是通過(guò)這個(gè)服務(wù)控制臺來(lái)實(shí)現驅動(dòng)程序服務(wù)的安裝的。
當初的實(shí)現是這樣的，通過(guò)編寫(xiě)一個(gè) DLL 來(lái)調用服務(wù)控制臺 API 從而完成驅動(dòng)程序的安裝，
然后再在 C# (應用程序是使用的 C# WinForm ，驅動(dòng)程序必須和這個(gè)應用程序通信)中通過(guò)平臺調用，
訪(fǎng)問(wèn)這個(gè) DLL ，這樣就可以實(shí)現驅動(dòng)程序的動(dòng)態(tài)加載以及動(dòng)態(tài)啟動(dòng)服務(wù)和停止服務(wù)等等操作了。
而在下面呢，我也算是對以前寫(xiě)的那個(gè) DLL 做一個(gè)總結，將其總結為一個(gè) C# 類(lèi)，這樣以后用起來(lái)會(huì )更加方便。
整個(gè)的類(lèi)，我按分層的思想將其分為三塊（其實(shí)這里將其這樣劃分不是非常合適）：
DriverEntity.cs
這里即是所謂的實(shí)體層，在該類(lèi)下面呢，主要包括的是將要在 DriverBLL 中使用到的一些常量數據，
這些數據呢包括服務(wù)的類(lèi)型，服務(wù)啟動(dòng)類(lèi)型，當然也包括了將會(huì )使用到的一些結構類(lèi)型等等信息。

這個(gè)類(lèi)即是所謂的數據訪(fǎng)問(wèn)層，
一般來(lái)說(shuō)，數據訪(fǎng)問(wèn)層用在使用數據庫的情況下比較合適，
但是在這里我將其抽象為只要是提供最基本的數據服務(wù)的 API ，我都將其放在數據訪(fǎng)問(wèn)層中，
所以這里主要是 C# 平臺調用時(shí)，對于將要調用的 Win32 API 的一個(gè)聲明，
其中包括了 CreateFile ，OpenService 等等 API 的聲明。
