?? 最近出差在北京做一個(gè)小項(xiàng)目，項(xiàng)目里需要讀取配置文件的小功能，覺得挺有參考意義的就把代碼發(fā)上來給大家參考一下。我們選擇了直接用微軟的讀取配置文件的方法。

?

這個(gè)是程序的運(yùn)行設(shè)計(jì)效果，就是把這些參數(shù)可以進(jìn)行靈活設(shè)置，靈活保存設(shè)置狀態(tài)。

?

程序編譯后自動(dòng)會(huì)產(chǎn)生相應(yīng)的配置文件，是跟項(xiàng)目的名稱一樣的配置文件。

?

讀取配置文件及保存配置的具體代碼參考如下，希望能給你節(jié)省一些時(shí)間，直接復(fù)制粘貼這個(gè)代碼就可以用了：
