To know what keys to modify/add, see the accepted answer here: Add menu item to windows context menu only for specific filetype

To add the keys using C#, use a RegistryKey object

string[] exts = {".pdf", ".doc"};
foreach (string ext in exts)
{
    RegistryKey _key = Registry.ClassesRoot.OpenSubKey($"HKEY_CLASSES_ROOT\\{ext}\\shell", true);
    RegistryKey newkey = _key.CreateSubKey("Use Virtual Printer");

    RegistryKey subNewkey = newkey.CreateSubKey("Command");
    subNewkey.SetValue("", "C:\\yourApplication.exe");
    subNewkey.Close();

    newkey.Close();
    _key.Close();
}
