得到本地路徑，不管用戶如何瀏覽它

Question

我有一個我已經構建的應用程序，並且我已將它放在服務器上的共享驅動器上，以便將其分發給其他用戶。但是，我希望應用程序檢查它正在啓動的位置，如果它直接在共享上啓動，則會彈出一條消息，其中顯示如下所示：「應用程序無法從此位置運行。是否要將其安裝在你的本地電腦呢？「

我遇到的問題如下：因爲用戶通過瀏覽到共享啓動它，應用程序中的CurrentDomain與用戶瀏覽共享的方式有關。因此，基本上不可能（這是我的問題:)確定應用程序是否在服務器上啓動！

如果用戶手動瀏覽到該共享通過鍵入：
\\SERVER\SharedFolder\App\MyApp.exe
然後執行assemly總是返回UNC共享（\ ...）...

然而，如果用戶被遠程處理到服務器，路徑會是這樣：
D:\Shares\MyAppSharedFolder\Loader\MyApp.exe

如果用戶同時存在着SharedFolder映射到自己的本地驅動器Z：
Z:\App\MyApp.exe
然後返回的值是Z：\值。

所以我的問題是：是否有一種簡單的方法可以始終獲得相同的值，無論用戶在啓動後如何瀏覽應用程序？

我想這個解決方案：

但是，這隻能如果路徑是UNC共享格式（\ ...）

那麼，什麼是讓正在運行的.exe文件的有道TRUE本地路徑，無論它正在運行還是瀏覽方式如何？

Answer 1

好吧，所以這裏是我最終做的......不，這個問題沒有答案/不是重複的。

總之，我的問題的答案是這樣的：
它不能完成/沒有簡單的內置方式來知道應用程序在哪裏運行真正的運行沒有考慮到「用戶域/資料/語境」。

因此，更爲複雜和全面的解決方案有以下方式（僞碼），以實現：

 

Make RunLocation = GetEntryAssembly! 

IF RunLocation == ServerLocationAsUNC OR LocalServerLocation 
{ 
//so here, if the location is \\SERVER\SharedFolder\App\ OR D:\Shares\MyAppSharedFolder\Loader\ 
    PROMPT FOR INSTALL LOCATION/DO NOT RUN! 
} 
ELSE 
{ 
    IF RunLocation Starts With a "\\" 
    { 
     Extract the Server name from RunLocation 
     Get the IP Address of that server 

     IF RunLocationIP == KnownServerIP 
     { 
      PROMPT FOR INSTALL LOCATION/DO NOT RUN! 
     } 
     ELSE 
     { 
      ALLOW TO RUN! 
     } 
    } 
    ELSE (if RunLocation does NOT start with a "\\") 
    { 
     Get the DriveInfo for RunLocation (example: "E:\") 
     IF the DriveInfo is NOT a Network Location 
     { 
      ALLOW TO RUN! 
     } 
     ELSE 
     { 
      Using ManagementObject, Get the UNC path for that DriveInfo 
      Extract the Server name from UNCPath 
      Get the IP Address of that server 

      IF DriveLocationIP == KnownServerIP 
      { 
       PROMPT FOR INSTALL LOCATION/DO NOT RUN! 
      } 
      ELSE 
      { 
       ALLOW TO RUN! 
      } 
     } 
    } 
} 

所以這是僞代碼版本...

這裏的實際方法我結束了建設檢查這一點，並在任何我需要它的地方使用它...請記住，這不是完美的（例如，如果本地PC具有相同的預期本地服務器路徑，並選擇，它會提示對於安裝位置，當它不應該，我真的不介意我自己），它是爲我的需要而建立的，所以我在那裏有一些額外的檢查（像，不能是桌面），你可能不需要...但不管，這裏是實際的編碼版本。
