運行后點(diǎn)擊按鈕：
，然后重啟后點(diǎn)擊按鈕：
發(fā)現沒(méi)？開(kāi)機自動(dòng)啟動(dòng)后
Environment.CurrentDirectory 發(fā)生了變更，
這樣在在我們程序中原本如果使用相對路徑進(jìn)行處理的，就找不見(jiàn)相應的文件了，
怎么處理？
方法1：
在程序初始化的時(shí)候改變下當前路徑
public Form1() { InitializeComponent(); Environment.CurrentDirectory = AppDomain.CurrentDomain.BaseDirectory; }方法2：添加環(huán)境變量 , 計算行--屬性--高級系統設置--環(huán)境變量--系統變量里面設置.
