本文實(shí)例為大家分享了C#讀寫共享文件夾的具體代碼，供大家參考，具體內(nèi)容如下
該試驗(yàn)分以下步驟：
1、在服務(wù)器設(shè)置一個(gè)共享文件夾，在這里我的服務(wù)器ip地址是10.80.88.180，共享文件夾名字是test，test里面有兩個(gè)文件：good.txt和bad.txt，訪問權(quán)限，用戶名是admin，密碼是admin。
2、新建一個(gè)webapplication項(xiàng)目，在前臺(tái)頁(yè)面加一個(gè)listbox，ID是ListBox1.
3、添加后臺(tái)代碼如下：其中包含的功能是讀文件，這里以讀good 文件為例；寫文件，這里以寫bad文件為例；還有是將test文件夾下的文件名列到listbox中。
