2025-03-05 ERROR: System.Environment.SpecialFolder'
- ERROR: System.Environment.SpecialFolder' does not contain a definition for 'CommonApplicationData'
Local Backup
- As per the Exceptions section of documentation,the above exception is thrown when
- ArgumentException ——- folder is not a member of System.Environment.SpecialFolder.
- It means the OS where you are running this command does not have Environment.SpecialFolder.CommonApplicationData as one of the special folder.
- For knowledge,
- Environment.SpecialFolder.ApplicationData is the most common one. This folder holds per-user, non-temporary application-specific data, other than user documents. A common example would be a settings or configuration file.
- Environment.SpecialFolder.CommonApplicationData is similar, but shared across users. You could use this to store document templates, for instance.
- Environment.SpecialFolder.LocalApplicationData is a non-roaming alternative for ApplicationData. As such, you'd never store important data there. However, because it's non-roaming it is a good location for temporary files, caches, etcetera. It's typically on a local disk.
- I think the problem may be that Environment.SpecialFolder.CommonApplicationData is common and shared between different users and the user with which you have logged in is not having rights to access the folder or the Visual Studio has not been started in Admin mode.
- EDIT Look at link and try to add a manual registry Common AppData defined in the
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\
CSIDL
- CSIDL (constant special item ID list) values provide a unique system-independent way to identify special folders used frequently by applications, but which may not have the same name or location on any given system. For example, the system folder may be “C:\Windows” on one system and “C:\Winnt” on another. These constants are defined in Shlobj.h.

Visual Studio 安裝程式：如何定位 Windows 公用文件資料夾？
- 我正在創建一個桌面應用程序，需要將 SDF 文件安裝到SpecialFolder.CommonDocuments資料夾中（C:\Users\Public\documents在 Win 7 中）。在 Visual Studio 桌面部署專案中，如何在檔案系統編輯器中指定此資料夾？
- 我嘗試在檔案系統編輯器中建立自訂資料夾，並將其指向屬性窗格中的 CommonDocuments 資料夾，如下所示：
- 不幸的是，這個規範無法實現。我不想對資料夾路徑進行硬編碼，因為它在 Windows 版本之間有所不同。那麼，如何在檔案系統編輯器中指定 CommonDocuments 資料夾？感謝您的幫助。
Solution
- 我弄清楚了這一點，並將其記錄下來以供內部使用。因此，我在此重印該文章：
- Visual Studio 部署專案不直接支援 CommonDocuments 資料夾，但我們可以使用具有「搜尋目標機器」任務的啟動條件編輯器來新增此支援。我們將使用該任務在 Windows 登錄中搜尋公用文件資料夾的路徑，並將結果指派給名為 COMDOCFOLDER 的安裝程式屬性（實際上是一個變數）。然後我們將使用該變數來設定檔案系統編輯器中自訂資料夾的路徑。
- 以下是執行任務的步驟。首先，在 Visual Studio 部署專案中開啟啟動條件編輯器：
- 右鍵單擊“搜尋目標機器”，然後從上下文選單中選擇“新增註冊表搜尋”。將會出現一個新項目（見上文 1）。說出它的名字Get Common Documents Folder。在屬性窗格中（請參閱上面的 2），將「Property」屬性（我們的變數的名稱）設為COMDOCFOLDER，將「Root」屬性（要搜尋的登錄根鍵）設為vsdrrHKLM，並將「RegKey」屬性（要尋找的登錄機碼鍵）設為SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders。請注意，我們從“RegKey”屬性中省略了根鍵。最後，將「Value」屬性（我們在登錄項目中搜尋的值的名稱）設為Common Documents。 COMDOCFOLDER 變數現在將保存公共文件資料夾的路徑。
- 接下來，前往 Visual Studio 部署專案中的檔案系統編輯器：
- 右鍵單擊“目標電腦上的檔案系統”，然後從上下文選單中選擇“新增特殊資料夾>自訂資料夾”。將會出現一個新項目（見上文 1）。重新命名該項目Common Documents。在屬性窗格中（請參閱上面的 2），將「Property」屬性設為COMDOCFOLDER。我將「DefaultLocation」屬性設定為 Windows Vista 及更高版本的 CommonDocuments 資料夾的硬編碼值；僅當 COMDOCFOLDER 屬性傳回空值時才會使用此值，但這種情況不應該發生。安裝程式現在有一個公用文件資料夾，該資料夾指向公共文件資料夾，如 Windows 註冊表中所指定的。
- 此 Microsoft 支援方法中提供了更多資訊。
