Adding a new item to context menu of Windows Explorer in C#.Net

Requirement: Whenever user right clicks on any folder in windows explorer, display a new option and if user selects that option, launch your application. The below steps will add a new option on right click of any folder:

You would need to add 2 sub keys in registry at the below location:

HKEY_CLASSES_ROOT\Folder\shell

Key 1: Folder\\shell\\MyProduct

Set the value of above key and the same will be shown in the context menu. You can also add a icon to the context menu item by adding a value to the key 1 and name it "Icon" as shown below:

Icon  "Path to your icon file"

Key 2: Folder\\shell\\MyProduct\\command

Set the value of above key and it will launch the application:

Eg. C:\Program Files (x86)\myProduct.exe "%1"

Here "%1" will give the path of the folder which is right clicked.

Programmatically this can be done as below:

private static void updateRegistryToAddContextMenu()

        {

            string MenuName = "Folder\\shell\\MyProduct";

            string Command = "Folder\\shell\MyProduct\\command";

            RegistryKey regmenu = null;

            RegistryKey regcmd = null;

            try

            {

                regmenu = Registry.ClassesRoot.CreateSubKey(MenuName);

                if (regmenu != null)

                    regmenu.SetValue("","New context menu option");

                regcmd = Registry.ClassesRoot.CreateSubKey(Command);

                if (regcmd != null)

                {

                    string exePath = Application.ExecutablePath;

                    regcmd.SetValue("", exePath + " " + "\"" + "%1" + "\"");

                }

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message);

            }

            finally

            {

                if (regmenu != null)

                    regmenu.Close();

                if (regcmd != null)

                    regcmd.Close();

            }

        }
