C＃获取特殊文件夹 [英] C# Get Special Folder

问题描述

请你只回答
otherways没有对这个问题作出回应。

让我重新开始。我如何使用这个类，它扩展了内部Environment.GetSpecialFolder？

。我不希望specialroots

 根= Environment.GetFolderPath（Environment.SpecialFolder）
  

由于我要使用此用于其它目的而不是.NET的。

例如我怎么叫（收藏夹= 6）通过一个按钮的位置单击？

解决方案

编辑：如果你继承你已经告诉我们，需要使用它的一些原因，代码（而不是内置，似乎做同样的事情.NET方法），你应该能够使用这样的：

 路径字符串= EnvironmentFolders.GetPath（EnvironmentFolders.SpecialFolders.Fonts）; 
  

话虽如此，在环保类有，做几乎同样的事情的公共方法， GetFolderPath ：

 路径字符串= Environment.GetFolderPath（Environment.SpecialFolder.Favorites）; 
  

的

的在.NET中反映的代码看起来很像在你的类中的代码，但它增加了两件事情：它验证参数值在枚举定义（因为你可以传递给方法的任何整数）它要求调用者有路径发现权限（一个新的的FileIOPermission ）。难道你想解决这最后的要求？

这两种方法的静态，这意味着你通过类型访问它们包含它们，不是那种类型的实例：

  //筛选
 EnvironmentFolders.GetPath（...）; 
 
 //不是这个
 EnvironmentFolders文件夹=新EnvironmentFolders（）; 
 folders.GetPath（...）; 
  

请参阅有关的静态类和静态类成员了解详情。

please just answer the question otherways do not respond to this question.

let me start again. How do I use this class, which extends the internal Environment.GetSpecialFolder?

IDon't want specialroots

root = Environment.GetFolderPath(Environment.SpecialFolder)

because i want to use this for other purposes Instead of .net.

for example how do I call (Favorites = 6) location by a button click?

public class EnvironmentFolders
{

public enum SpecialFolder
{
    AdministrativeTools = 48,
    //{user name}\Start Menu\Programs\Administrative Tools 
    ApplicationData = 26,
    //{user name}\Application Data 
    CommonAdministrativeTools = 47,
    //All Users\Start Menu\Programs\Administrative Tools 
    CommonApplicationData = 35,
    //All Users\Application Data 
    CommonDesktopDirectory = 25,
    //All Users\Desktop 
    CommonDocuments = 46,
    //All Users\Documents 
    CommonFavorites = 31,
    CommonNonLocalizedStartup = 30,
    //non localized common startup 
    CommonPrograms = 23,
    //All Users\Programs 
    CommonStartMenu = 22,
    //All Users\Start Menu 
    CommonStartup = 24,
    //All Users\Startup 
    CommonTemplates = 45,
    //All Users\Templates 
    ControlPanel = 3,
    //My Computer\Control Panel 
    Cookies = 33,
    DesktopDirectory = 16,
    //{user name}\Desktop 
    Favorites = 6,
    //{user name}\Favorites 
    Fonts = 20,
    //windows\fonts 
    History = 34,
    InternetCache = 32,
    LocalApplicationData = 28,
    //{user name}\Local Settings\Application Data (non roaming) 
    MyDocuments = 5,
    //My Documents 
    MyPictures = 39,
    //C:\Program Files\My Pictures 
    NetworkShortcuts = 19,
    //{user name}\nethood 
    NonLocalizedStartup = 29,
    //non localized startup 
    Printers = 4,
    //My Computer\Printers 
    PrintHood = 27,
    //{user name}\PrintHood 
    ProgramFiles = 38,
    //C:\Program Files 
    ProgramFilesCommon = 43,
    //C:\Program Files\Common 
    Programs = 2,
    //Start Menu\Programs 
    Recent = 8,
    //{user name}\Recent 
    RecycleBin = 10,
    //{desktop}\Recycle Bin 
    SendTo = 9,
    //{user name}\SendTo 
    StartMenu = 11,
    //{user name}\Start Menu 
    Startup = 7,
    //Start Menu\Programs\Startup 
    System = 37,
    //GetSystemDirectory() 
    Templates = 21,
    UserProfile = 40,
    //USERPROFILE 
    Windows = 36
    //GetWindowsDirectory() 
}

[DllImport("shfolder.dll", CharSet = CharSet.Auto)]
private static extern int SHGetFolderPath(IntPtr hwndOwner, int nFolder, IntPtr hToken, int dwFlags, StringBuilder lpszPath);

/// <summary> 
/// Get an environment folder path for Windows environment folders 
/// </summary> 
/// <returns>A string pointing to the special path</returns> 
/// <remarks></remarks> 
public static string GetPath(SpecialFolder folder)
{
    StringBuilder lpszPath = new StringBuilder(260);
    SHGetFolderPath(IntPtr.Zero, (int)folder, IntPtr.Zero, 0, lpszPath);
    return lpszPath.ToString();
}
}

解决方案

Edit: if you've inherited the code you've shown us and need to use it for some reason (instead of the built-in .NET method that appears to do the same thing), you should be able to use it like this:

string path = EnvironmentFolders.GetPath(EnvironmentFolders.SpecialFolders.Fonts);

Having said that, the Environment class has a public method that does nearly the same thing, GetFolderPath:

string path = Environment.GetFolderPath(Environment.SpecialFolder.Favorites);

The reflected code in .NET looks exactly like the code in your class, except it adds two things: it verifies that the parameter value is defined in the enumeration (since you can pass any integer to the method) and it demands that the caller has path discovery permission (a new FileIOPermission). Is it that last requirement you're trying to work around?

Both methods are static, meaning you access them through the type that contains them, not an instance of that type:

 // Like this
 EnvironmentFolders.GetPath(...);

 // Not this
 EnvironmentFolders folders = new EnvironmentFolders();
 folders.GetPath(...);

See the .NET documentation about Static Classes and Static Class Members for more information.
