Vb.net 請(qǐng)問如何快速時(shí)時(shí)讀取共享文件夾資料

File.WriteAllText("\\10.1.37.222\shared\temp.txt", "");

十余年的長(zhǎng)嶺網(wǎng)站建設(shè)經(jīng)驗(yàn)，針對(duì)設(shè)計(jì)、前端、開發(fā)、售后、文案、推廣等六對(duì)一服務(wù)，響應(yīng)快，48小時(shí)及時(shí)工作處理。網(wǎng)絡(luò)營(yíng)銷推廣的優(yōu)勢(shì)是能夠根據(jù)用戶設(shè)備顯示端的尺寸不同，自動(dòng)調(diào)整長(zhǎng)嶺建站的顯示方式，使網(wǎng)站能夠適用不同顯示終端，在瀏覽器中調(diào)整網(wǎng)站的寬度，無論在任何一種瀏覽器上瀏覽網(wǎng)站，都能展現(xiàn)優(yōu)雅布局與設(shè)計(jì)，從而大程度地提升瀏覽體驗(yàn)。創(chuàng)新互聯(lián)公司從事“長(zhǎng)嶺網(wǎng)站設(shè)計(jì)”,“長(zhǎng)嶺網(wǎng)站推廣”以來，每個(gè)客戶項(xiàng)目都認(rèn)真落實(shí)執(zhí)行。

如果能生成就沒問題。

用VB怎樣打開網(wǎng)絡(luò)上共享的文件（此文件所在目錄加有共享密碼）？

進(jìn)入共享文件夾可以用直接路徑的，不過如果要進(jìn)入共享文件夾下子文件夾里，要先進(jìn)入共享文件夾，然后再過，不然可能會(huì)出現(xiàn)文件查找不到(就算沒有密碼也有可能會(huì)出現(xiàn))例如：進(jìn)入局域網(wǎng)客戶機(jī)PC的共享文件夾basic下子文件夾file里的文件text.txt就要先訪問//pc/basic，寫入密碼，然后再進(jìn)入//pc/basic/file/text.txt

如果不用net use的方法，vb.net 有辦法訪問共享文件或者共享文件夾嗎

我不會(huì)VB，但是都是.net。c#的代碼稍微轉(zhuǎn)換一下就可以了。

C#實(shí)現(xiàn)訪問網(wǎng)絡(luò)共享文件夾，使用?WNetAddConnection2A?和?WNetCancelConnection2A。

在目標(biāo)服務(wù)器建立共享文件夾，建立訪問賬號(hào)test;
