    我为我们公司准备了一个应用程序,它必须以全球方式存储设置,这样拥有多种访问类型的员工就可以运行该程序。

    因此,我似乎找不到方法让我的应用程序将数据写入PC。错误总是相同的未授权访问异常。

    我尝试过使用以下路径,但都失败了:

    • C:\程序套件\
    • 环境.GetFolderPath(环境.SpecialFolder.ApplicationData)
    • 环境.GetFolderPath(环境.SpecialFolder.CommonApplicationData)

    我不想使用独立存储,因为我不想为每个登录到我们工厂的许多PC中的一台的个人配置应用程序。

    有没有办法说,“嘿,我的应用程序是管理员。给我权限!“???

    我们目前仅限于.NET Framework 3.5。

    :

    我使用CommonApplicationData,它似乎可以正常工作,但有一点需要注意。我发现如果管理员在CommonApplicationData路径中创建子目录,那么其他“非管理员”用户就不能删除该目录。您可能需要添加 FileSystemAccessRule

    编辑:使用代码段。 

    public static void CreateWithEveryoneFullControlIfAdmin(this DirectoryInfo source)
{
    if (IsAdmin())
    {
        DirectorySecurity directorySecurity = Directory.GetAccessControl(Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData));
        FileSystemAccessRule accessRule
            = new FileSystemAccessRule(@"BUILTIN\Users", FileSystemRights.FullControl,
                InheritanceFlags.ObjectInherit | InheritanceFlags.ContainerInherit,
                PropagationFlags.None,
                AccessControlType.Allow);

        bool modified = false;
        directorySecurity.ModifyAccessRule(AccessControlModification.Add,
            accessRule,
            out modified);

        if (modified)
        {
            source.Create(directorySecurity);
        }
        else
        {
            source.Create();
        }
    }
    else
    {
        source.Create();
    }
}

public static bool IsAdmin()
{
    WindowsIdentity identity = WindowsIdentity.GetCurrent();
    WindowsPrincipal principal = new WindowsPrincipal(identity);
    return principal.IsInRole(WindowsBuiltInRole.Administrator);
}

    我知道你说过你不想使用IsolatedStorage,因为你不想每个用户都有自己的设置。

    但是你看过使用机器存储的隔离存储吗?如果我理解正确(我可能是错的,这不是第一次),这应该是所有访问你的应用程序的用户共享的。 

    using(IsolatedStorageFile store = IsolatedStorageFile.GetMachineStoreForApplication())
{
    // check if file exists or not
    try
    {
        using(IsolatedStorageFileStream isfs = new IsolatedStorageFileStream(STG_FILE_NAME, FileMode.OpenOrCreate, store)) {
            StreamWriter sw = new StreamWriter(isfs);
            foreach(string key in m_values.Keys) {
                sw.WriteLine(key + "::" + m_values[key]);
            } // foreach
            sw.Flush();
        } // using
    } catch(IOException) {
        // generally because file is locked by another process...do nothing
    }
} // using

    或者,您可以更改应用程序配置文件的权限以允许所有人访问。这可以由特权用户在应用程序第一次运行时完成。

    http://www.techtalkz.com/c-c-sharp/153732-saving-files-so-any-user-can-access-them.html 

    FileInfo fileInfo = new FileInfo(path);
FileSecurity fileSecurity = fileInfo.GetAccessControl();
fileSecurity.AddAccessRule(new FileSystemAccessRule(
    "Users",
    FileSystemRights.FullControl,
    AccessControlType.Allow) );

fileInfo.SetAccessControl(fileSecurity);

    好的,这是我的两分钱,希望对你有帮助。

    如果可以在程序中硬编码一些管理级凭据,则可以对需要访问文件夹的代码部分使用模拟。请看这里:
