最近在倒騰中控指紋儀，用的是官方提供的sdk 地址
??? 在使用過程中需要對進(jìn)出記錄進(jìn)行實(shí)時監(jiān)控，開發(fā)包也有這個功能，不使用多線程winform下連接一臺指紋儀正常，可以反饋事件，代碼如下

不使用多線程連接一臺指紋儀
??? 但如果連接多臺設(shè)備就必須用多個線程（如使用單線程一臺指紋儀連接有問題就會整個卡死），一個線程對應(yīng)一個指紋儀，但線程執(zhí)行完了就回收了，無法響應(yīng)事件或用while(true) sleep(1000)阻止回收也不行

新建線程連接（記事本寫的，可能有錯，就是這個意思）
?? 這個SDK到底是什么原理，它實(shí)例化之后是否就附加在實(shí)例化它的那個線程上？線程回收了，它也就回收了？
?? 這SDK是否自己會新建線程用于響應(yīng)事件？為什么在winform下就能響應(yīng)，而新建線程就不行呢？
??本人野路子，沒有學(xué)習(xí)過，純屬個人愛好，不要吐槽以上文字，理解意思就行。。????
