Create a shortcut on Desktop

I want to create a shortcut pointing to some EXE file, on the desktop, using .NET Framework 3.5 and relying on an official Windows API. How can I do that?

Here's a (Tested) Extension Method, with comments to help you out.

using IWshRuntimeLibrary;
using System;

namespace Extensions
{
    public static class XShortCut
    {
        /// <summary>
        /// Creates a shortcut in the startup folder from a exe as found in the current directory.
        /// </summary>
        /// <param name="exeName">The exe name e.g. test.exe as found in the current directory</param>
        /// <param name="startIn">The shortcut's "Start In" folder</param>
        /// <param name="description">The shortcut's description</param>
        /// <returns>The folder path where created</returns>
        public static string CreateShortCutInStartUpFolder(string exeName, string startIn, string description)
        {
            var startupFolderPath = Environment.SpecialFolder.Startup.GetFolderPath();
            var linkPath = startupFolderPath + @"\" + exeName + "-Shortcut.lnk";
            var targetPath = Environment.CurrentDirectory + @"\" + exeName;
            XFile.Delete(linkPath);
            Create(linkPath, targetPath, startIn, description);
            return startupFolderPath;
        }

        /// <summary>
        /// Create a shortcut
        /// </summary>
        /// <param name="fullPathToLink">the full path to the shortcut to be created</param>
        /// <param name="fullPathToTargetExe">the full path to the exe to 'really execute'</param>
        /// <param name="startIn">Start in this folder</param>
        /// <param name="description">Description for the link</param>
        public static void Create(string fullPathToLink, string fullPathToTargetExe, string startIn, string description)
        {
            var shell = new WshShell();
            var link = (IWshShortcut)shell.CreateShortcut(fullPathToLink);
            link.IconLocation = fullPathToTargetExe;
            link.TargetPath = fullPathToTargetExe;
            link.Description = description;
            link.WorkingDirectory = startIn;
            link.Save();
        }
    }
}

And an example of use:

XShortCut.CreateShortCutInStartUpFolder(THEEXENAME, 
    Environment.CurrentDirectory,
    "Starts some executable in the current directory of application");

1st parm sets the exe name (found in the current directory) 2nd parm is the "Start In" folder and 3rd parm is the shortcut description.

Example of Using this code

The naming convention of the link leaves no ambiguity as to what it will do. To test the link just double click it.

Final Note: the application itself (target) must have an ICON image associated with it. The link is easily able to locate the ICON within the exe. If the target application has more than one icon, you may open the link's properties and change the icon to any other found in the exe.

URL shortcut

private void urlShortcutToDesktop(string linkName, string linkUrl)
{
    string deskDir = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);

    using (StreamWriter writer = new StreamWriter(deskDir + "\\" + linkName + ".url"))
    {
        writer.WriteLine("[InternetShortcut]");
        writer.WriteLine("URL=" + linkUrl);
    }
}

Application shortcut

private void appShortcutToDesktop(string linkName)
{
    string deskDir = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);

    using (StreamWriter writer = new StreamWriter(deskDir + "\\" + linkName + ".url"))
    {
        string app = System.Reflection.Assembly.GetExecutingAssembly().Location;
        writer.WriteLine("[InternetShortcut]");
        writer.WriteLine("URL=file:///" + app);
        writer.WriteLine("IconIndex=0");
        string icon = app.Replace('\\', '/');
        writer.WriteLine("IconFile=" + icon);
    }
}

Also check this example.

If you want to use some API specific functions then you will want to use the IShellLink interface as well as the IPersistFile interface (through COM interop).

Here is an article that goes into detail what you need to do it, as well as sample code.

Thorarin On

You can use this ShellLink.cs class to create the shortcut.

To get the desktop directory, use:

var dir = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);

or use Environment.SpecialFolder.CommonDesktopDirectory to create it for all users.

With additional options such as hotkey, description etc.

At first, Project > Add Reference > COM > Windows Script Host Object Model.

using IWshRuntimeLibrary;

private void CreateShortcut()
{
  object shDesktop = (object)"Desktop";
  WshShell shell = new WshShell();
  string shortcutAddress = (string)shell.SpecialFolders.Item(ref shDesktop) + @"\Notepad.lnk";
  IWshShortcut shortcut = (IWshShortcut)shell.CreateShortcut(shortcutAddress);
  shortcut.Description = "New shortcut for a Notepad";
  shortcut.Hotkey = "Ctrl+Shift+N";
  shortcut.TargetPath = Environment.GetFolderPath(Environment.SpecialFolder.System) + @"\notepad.exe";
  shortcut.Save();
}

If you want a simple code to put on other location, take this:

using IWshRuntimeLibrary;

WshShell shell = new WshShell();
IWshShortcut shortcut = shell.CreateShortcut(@"C:\FOLDER\SOFTWARENAME.lnk");
shortcut.TargetPath = @"C:\FOLDER\SOFTWARE.exe";
shortcut.Save();

For Windows Vista/7/8/10, you can create a symlink instead via mklink.

Process.Start("cmd.exe", $"/c mklink {linkName} {applicationPath}");

Alternatively, call CreateSymbolicLink via P/Invoke.

I have created a wrapper class based on Rustam Irzaev's answer with use of IWshRuntimeLibrary.

        string originalFilePath = Path.GetDirectoryName(originalFilePathAndName);

        string link = destinationSavePath + Path.DirectorySeparatorChar + fileName + ".lnk";
        var shell = new WshShell();
        var shortcut = shell.CreateShortcut(link) as IWshShortcut;
        if (shortcut != null)
        {
            shortcut.TargetPath = originalFilePathAndName;
            shortcut.WorkingDirectory = originalFilePath;
            shortcut.Save();
        }
    }

    public static void CreateStartupShortcut()
    {
        CreateShortcut(System.Reflection.Assembly.GetEntryAssembly()?.Location, Environment.GetFolderPath(Environment.SpecialFolder.Startup));

I use "Windows Script Host Object Model" reference to create shortcut.

Adding "Windows Script Host Object Model" to project references

and to create shortcut on specific location:

    void CreateShortcut(string linkPath, string filename)
    {
        // Create shortcut dir if not exists
        if (!Directory.Exists(linkPath))
            Directory.CreateDirectory(linkPath);

        // shortcut file name
        string linkName = Path.ChangeExtension(Path.GetFileName(filename), ".lnk");

        // COM object instance/props
        IWshRuntimeLibrary.WshShell shell = new IWshRuntimeLibrary.WshShell();
        IWshRuntimeLibrary.IWshShortcut sc = (IWshRuntimeLibrary.IWshShortcut)shell.CreateShortcut(linkName);
        sc.Description = "some desc";
        //shortcut.IconLocation = @"C:\..."; 
        sc.TargetPath = linkPath;
        // save shortcut to target
        sc.Save();
    }

I Use simply for my app:

using IWshRuntimeLibrary; // > Ref > COM > Windows Script Host Object  
...   
private static void CreateShortcut()
    {
        string link = Environment.GetFolderPath( Environment.SpecialFolder.Desktop ) 
            + Path.DirectorySeparatorChar + Application.ProductName + ".lnk";
        var shell = new WshShell();
        var shortcut = shell.CreateShortcut( link ) as IWshShortcut;
        shortcut.TargetPath = Application.ExecutablePath;
        shortcut.WorkingDirectory = Application.StartupPath;
        //shortcut...
        shortcut.Save();
    }

Use ShellLink.cs at vbAccelerator to create your shortcut easily !

private static void AddShortCut()
{
using (ShellLink shortcut = new ShellLink())
{
    shortcut.Target = Application.ExecutablePath;
    shortcut.WorkingDirectory = Path.GetDirectoryName(Application.ExecutablePath);
    shortcut.Description = "My Shorcut";
    shortcut.DisplayMode = ShellLink.LinkDisplayMode.edmNormal;
    shortcut.Save(SHORTCUT_FILEPATH);
}
}
