I want to add section number when referencing blocks. MWE is as follows:

documentclass[serif,12pt,xcolor=dvipsnames]{beamer}

usetheme{Madrid} 

usepackage{lipsum}  

begin{document}



begin{frame}{Example ref{block1}}

section{}

begin{block}{}label{block1}

lipsum[2]

end{block}

end{frame}



end{document}

This is what I have at the moment:

But I would like to have the following:

Many thanks in advance!

The problem is actually more tricky than you make it look. The main problem is that blocks are not numbered in beamer and if you label them, you will get the framenumber and not the number of the block.

You can modify the definition of the block environment to include a counter. Once blocks are numbered you can use @marmots great suggestion and use numberwithin{block}{section} to include the section number.

Additional comment: never ever use section inside a frame, this can have serve side-effects.

documentclass[12pt,xcolor=dvipsnames]{beamer}

usefonttheme{serif}

usetheme{Madrid} 

usepackage{lipsum}



newcounter{block}

setcounter{block}{0}

numberwithin{block}{section}



setbeamertemplate{block begin}

{%

    refstepcounter{block}%

  parvskipmedskipamount%

  begin{beamerboxesrounded}[upper=block title,lower=block body,shadow=true]%

    {raggedrightusebeamerfont*{block title}insertblocktitle}%

    raggedright%

    usebeamerfont{block body}%

}



begin{document}



section{}

begin{frame}{Example ref{block1}}

begin{block}{}label{block1}

lipsum[2]

end{block}

end{frame}



begin{frame}

end{frame}



begin{frame}{Example ref{block2}}

begin{block}{}label{block2}

lipsum[2]

end{block}

end{frame}
