C# Copy powerpoint Master Slide layout
<p>I want to copy master layout from one presentation to another. 
If I wanted to copy a slide the code would be <code>Presentation.Slides[1].Copy</code>, however I can't find similar code for copying master layout. There is  <code>Presentation.SlideMaster.Delete()</code> but for some reason there is no copy. If it is not possible in c# is it possible in vba??</p>

<p>I want to basically automate <a href="https://support.office.com/en-us/article/Copy-and-paste-a-slide-master-from-one-presentation-to-another-ab99cf07-3a65-4f50-9d24-f17444a3df9b" rel="nofollow noreferrer">this</a></p>
