C# Windows ‘Open With >’ Context menu behaviour [duplicate]

by

The Open With command just passes the path of the file as the first argument to the application so all you need to do is

public static void Main(string[] args)
{
    if(args[0] != null)
    {
       //args[0] contans a path to the file do whatever you need to do to display it
    }
    else
    {
       //Start normally
    }
}

To automaticly put your program in the open with list you will need to add some reg keys in HKEY_CLASSES_ROOT\YOUR_EXT\. Here is a SO answer saying how to do it

Or you could just add it by hand to the open with list the normal way.
