C＃は「すべてのユーザーデスクトップ」のパスを取得します
C Get Path Ofall User Desktops
転載http://www.cnblogs.com/DoNetCShap/p/4221899.html
C＃を使用して、すべてのユーザーのデスクトップ（Public Desktop）へのパスを取得したいと思います。
とてもシンプルだと思いましたが
Environment.GetFolderPath(Environment.SpecialFolder.Desktop)現在のユーザーのデスクトップパスのみを取得できます。結局、C ++関数を呼び出す方法はありません。
[DllImport('shfolder.dll', CharSet = CharSet.Auto)] private static extern int SHGetFolderPath ( IntPtr hwndOwner, int nFolder, IntPtr hToken, int dwFlags, StringBuilder lpszPath ) private const int MAX_PATH = 260 private const int CSIDL_COMMON_DESKTOPDIRECTORY = 0x0019 public static string GetAllUsersDesktopFolderPath ( ) { StringBuilder sbPath = new StringBuilder(MAX_PATH) SHGetFolderPath(IntPtr.Zero, CSIDL_COMMON_DESKTOPDIRECTORY, IntPtr.Zero, 0, sbPath) return sbPath.ToString() }DLLのディレクトリを取得します
Assembly myAssembly = Assembly.GetEntryAssembly() string path = myAssembly.Location DirectoryInfo dr = new DirectoryInfo(path) Path=dr.Parent //Upper directory of the current directoryプログラムの現在のパスを取得するためのC＃メソッド
System.Environment.CurrentDirectory //Example: c: est Application.ExecutablePath (including name) //Example: c: estmyapp.exe Application.StartupPath (not including the name) //Example: c: est新しいプロセスコンポーネントを取得し、ファイル名（プロセス名）を含む現在アクティブなプロセスに関連付けるメインモジュールへのフルパス。
string str = System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName Result: X:xxxxxxxxx.exe (the directory where the .exe file is located +.exe file name)現在のディレクトリ（プロセスが開始されたディレクトリ）の完全修飾パスを取得および設定します。
string str = System.Environment.CurrentDirectory Result: X:xxxxxx (the directory where the .exe file is located) 現在のスレッドの現在のアプリケーションドメインのベースディレクトリを取得します。これは、アセンブリ競合リゾルバーがアセンブリをプローブするために使用します。
string str = System.AppDomain.CurrentDomain.BaseDirectory Result: X:xxxxxx (the directory where the .exe file is located +'') アプリケーションを含むディレクトリの名前を取得して設定します。
string str = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase Result: X:xxxxxx (the directory where the .exe file is located +'') 実行可能ファイルの名前を除いて、アプリケーションを起動した実行可能ファイルへのパスを取得します。
string str = System.Windows.Forms.Application.StartupPath Result: X:xxxxxx (the directory where the .exe file is located) 実行可能ファイルの名前を含む、アプリケーションを起動した実行可能ファイルへのパスを取得します。
string str = System.Windows.Forms.Application.ExecutablePath Result: X:xxxxxxxxx.exe (the directory where the .exe file is located +.exe file name)アプリケーションの現在の作業ディレクトリを取得します（ 信頼できない ）。
string str = System.IO.Directory.GetCurrentDirectory() Result: X:xxxxxx (the directory where the .exe file is located) Get system special folder path (favorite, desktop) 1、お気に入りのパス
System.Environment.GetFolderPath(System.Environment.SpecialFolder.Favorites)2、デスクトップパス
System.Environment.GetFolderPath(System.Environment.SpecialFolder.Desktop)詳細については、列挙型クラスSystem.Environment.SpecialFolderを参照してください。
