我試圖訪問需要身份驗證的samba共享。我不希望驅動器被映射。訪問Samba共享,無驅動器映射,IP地址 - C#

我目前已經與samba共享主機名向DNS註冊。它不適用於普通的IP地址。

我已經做了一些工作輪,使其在平均工作時間(加入hosts文件窗口)

這是我使用下面的代碼:

請參閱上面的鏈接。這都是關於UNC路徑。如果用戶嘗試使用您的程序無法被服務器識別,您仍然會遇到登錄。 – digitlworld 2011-12-21 19:45:21

我正在使用UNC路徑,我不能使用IP的唯一主機名 - 請參閱代碼 – rreeves 2011-12-21 20:23:23

如前所述:Access to a windows share through UNC path, before the session opening

這是一種重複的,但短期的版本是使用UNC路徑:

\\hostnameorIP\sharename\folder\within\share\file.txt

您應該能夠像對待其他任何文件C#和罰款,沒有映射。這也直接在Windows資源管理器中工作。我一直這樣做,因爲在工作映射導致My computer和其他Windows資源管理器的事情運行速度較慢,如果連接到共享緩慢(對我來說,這是)。

喜歡的東西:

using System.IO; 
FileStream lFileStream = new FileStream(@"\\hostnameorIP\sharename\folder\within\share\file.txt",...); 

// Do stuff with it 

應該正常工作。

@rreeves我不是在談論如何使用您的代碼。我正在談論使用帶有標準C#文件/目錄訪問方法和類的UNC路徑。 P/Invoke在這裏似乎有點不必要。當您嘗試使用UNC路徑訪問共享時,它應該考慮身份驗證,其餘的應該幾乎是無縫的。 – digitlworld 2011-12-21 20:41:37

遠程服務器實際上是Samba服務器還是其他類型的SMB服務器(如Windows)?

Samba將允許通過IP地址進行連接,但大多數其他SMB服務器(如Windows)通常不會。並要求您擁有NetBIOS名稱。
