C#實(shí)現(xiàn)密碼驗(yàn)證與輸錯(cuò)密碼賬戶鎖定_C#教程

作者：農(nóng)碼一生 ? 更新時(shí)間： 2022-06-14 編程語言

C#實(shí)現(xiàn)的Check Password，并根據(jù)輸錯(cuò)密碼的次數(shù)分情況鎖定賬戶：如果輸入錯(cuò)誤3次，登錄賬戶鎖定5分鐘并提示X點(diǎn)X分后重試登錄。如果5分鐘后再次輸入，累計(jì)輸入錯(cuò)誤密碼累計(jì)達(dá)到5次。則賬戶會(huì)被永久鎖定，需聯(lián)系系統(tǒng)管理員進(jìn)行把數(shù)據(jù)庫中的輸入錯(cuò)誤的次數(shù)（errorcount）進(jìn)行清零解鎖才能登陸。實(shí)現(xiàn)代碼如下：
