C#: Set And Unset Auto-start For Windows Application

I found this useful C# class in this MSDN forum that provides an easy way to enable and disable an application auto-run in Windows.

With a little modification, I made it to be easily called by any project. What you need to do is just pass in the 'Key Name' and 'Assembly Location' parameters.

Here is the complete class:

using Microsoft.Win32;

/// 

/// Utility.

/// 

public class Util

{

    private const string RUN_LOCATION = @"Software\Microsoft\Windows\CurrentVersion\Run";

    /// 

    /// Sets the autostart value for the assembly.

    /// 

    /// 
Registry Key Name

    /// 
Assembly location (e.g. Assembly.GetExecutingAssembly().Location)

    public static void SetAutoStart(string keyName, string assemblyLocation)

    {

        RegistryKey key = Registry.CurrentUser.CreateSubKey(RUN_LOCATION);

        key.SetValue(keyName, assemblyLocation);

    }

    /// 

    /// Returns whether auto start is enabled.

    /// 

    /// 
Registry Key Name

    /// 
Assembly location (e.g. Assembly.GetExecutingAssembly().Location)

    public static bool IsAutoStartEnabled(string keyName, string assemblyLocation)

    {

        RegistryKey key = Registry.CurrentUser.OpenSubKey(RUN_LOCATION);

        if (key == null)

            return false;

        string value = (string)key.GetValue(keyName);

        if (value == null)

            return false;

        return (value == assemblyLocation);

    }

    /// 

    /// Unsets the autostart value for the assembly.

    /// 

    /// 
Registry Key Name

    public static void UnSetAutoStart(string keyName)

    {

        RegistryKey key = Registry.CurrentUser.CreateSubKey(RUN_LOCATION);

        key.DeleteValue(keyName);

    }

}

Sample Usage:

string keyName = "MyProgramName";

string assemblyLocation = Assembly.GetExecutingAssembly().Location;  // Or the EXE path.

// Set Auto-start.

Util.SetAutoStart(keyName, assemblyLocation);

// Unset Auto-start.

if (Util.IsAutoStartEnabled(keyName, assemblyLocation))

    Util.UnSetAutoStart(keyName);
