[英]How to create a desktop shortcut (link), but with own shortcut file extension (e.g. .appfolder) instead of .lnk programmatically in C#?
I have registered a shortcut file extension named .appfolder in registry: reg export我在注册表中注册了一个名为 .appfolder 的快捷方式文件扩展名: reg export
It should behave like a normal .lnk shortcut, but has to have .appfolder ending (that has it reasons).它应该表现得像一个普通的 .lnk 快捷方式,但必须以 .appfolder 结尾(这是有原因的)。
Now I want to create an shortcut with that file ending/extension programmatically in C#.现在我想在 C# 中以编程方式创建一个带有该文件结尾/扩展名的快捷方式。 Default for .lnk ending it works with:
.lnk 结尾的默认值适用于:
public static void CreateShortcut(string shortcutName, string shortcutPath, string targetFileLocation)
{
string shortcutLocation = Path.Combine(shortcutPath, shortcutName + @".lnk");
WshShell shell = new WshShell();
IWshShortcut shortcut = (IWshShortcut)shell.CreateShortcut(shortcutLocation);
shortcut.Description = "My shortcut description";
shortcut.TargetPath = targetFileLocation;
shortcut.Save();
}
//e.g:
CreateShortcut("Example (Notepad)", Environment.GetFolderPath(Environment.SpecialFolder.Desktop),
"notepad.exe");
When I try to change file extension in this line string shortcutLocation = Path.Combine(shortcutPath, shortcutName + @".lnk");
当我尝试更改此行
string shortcutLocation = Path.Combine(shortcutPath, shortcutName + @".lnk");
文件扩展名时string shortcutLocation = Path.Combine(shortcutPath, shortcutName + @".lnk");
to .appfolder I get an System.Runtime.InteropServices.COMException
( HRESULT: 0x80020009 (DISP_E_EXCEPTION)
).到 .appfolder 我得到一个
System.Runtime.InteropServices.COMException
( HRESULT: 0x80020009 (DISP_E_EXCEPTION)
)。
When I try to change file extension after creating/saving shortcut with File.Move(shortcutLocation, Path.ChangeExtension(shortcutLocation, ".appfolder"));
当我在使用
File.Move(shortcutLocation, Path.ChangeExtension(shortcutLocation, ".appfolder"));
创建/保存快捷方式后尝试更改文件扩展名时File.Move(shortcutLocation, Path.ChangeExtension(shortcutLocation, ".appfolder"));
I get an file on desktop with following properties: image我在桌面上得到一个具有以下属性的文件:图像
As you can see Windows does recognize .appfolder extension as shortcut, but the 'Shortcut' tab is missing and when I double-click the file to execute, it happens nothing.正如您所看到的,Windows 确实将 .appfolder 扩展名识别为快捷方式,但缺少“快捷方式”选项卡,当我双击该文件以执行时,它什么也没发生。
So, either my registration of .appfolder is not complete right, although it should be... or how to create a shortcut with own shortcut file extension programmatically in C#?所以,要么我的 .appfolder 注册不完整,虽然它应该是......或者如何在 C# 中以编程方式创建一个具有自己的快捷方式文件扩展名的快捷方式?
Thanks for help ;)感谢帮助 ;)
EDIT :编辑 :
I tried another way to create the shortcut programatically:我尝试了另一种以编程方式创建快捷方式的方法:
void main() {
IShellLink link = (IShellLink)new ShellLink();
// setup shortcut information
link.SetDescription("My Description");
link.SetPath(@"notepad.exe");
// save it
IPersistFile file = (IPersistFile)link;
string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
file.Save(Path.Combine(desktopPath, "Notepad.appfolder"), false);
}

internal class ShellLink
{
}

[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
[Guid("000214F9-0000-0000-C000-000000000046")]
internal interface IShellLink
{
void GetPath([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszFile, int cchMaxPath, out IntPtr pfd, int fFlags);
void GetIDList(out IntPtr ppidl);
void SetIDList(IntPtr pidl);
void GetDescription([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszName, int cchMaxName);
void SetDescription([MarshalAs(UnmanagedType.LPWStr)] string pszName);
void GetWorkingDirectory([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszDir, int cchMaxPath);
void SetWorkingDirectory([MarshalAs(UnmanagedType.LPWStr)] string pszDir);
void GetArguments([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszArgs, int cchMaxPath);
void SetArguments([MarshalAs(UnmanagedType.LPWStr)] string pszArgs);
void GetHotkey(out short pwHotkey);
void SetHotkey(short wHotkey);
void GetShowCmd(out int piShowCmd);
void SetShowCmd(int iShowCmd);
void GetIconLocation([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszIconPath, int cchIconPath, out int piIcon);
void SetIconLocation([MarshalAs(UnmanagedType.LPWStr)] string pszIconPath, int iIcon);
void SetRelativePath([MarshalAs(UnmanagedType.LPWStr)] string pszPathRel, int dwReserved);
void Resolve(IntPtr hwnd, int fFlags);
void SetPath([MarshalAs(UnmanagedType.LPWStr)] string pszFile);
}
It creates the shortcut file without any error (like System.Runtime.InteropServices.COMException
, see above), but it doesn't execute the .exe file by double-clicking neither.它创建没有任何错误的快捷方式文件(如
System.Runtime.InteropServices.COMException
,见上文),但它不会通过双击两者来执行 .exe 文件。
