Hello, I would like to know if you can write these types of matrices, that is, place a vertical and horizontal line like in Latex, I have tried every possible way but I did not achieve my purpose. I am working in c# wpf WpfMath

`M =\left[
\begin{array}{c c c |c}
1 & 2 & 2 & 2\\
3 & 4 & 2 & 2\\ \hline
5 & 6 & 2 & 2\\
\end{array} \right] `

`M =\left[
\begin{array}{c c c :c}
1 & 2 & 2 & 2\\
3 & 4 & 2 & 2\\ \hdashline
5 & 6 & 2 & 2\\
\end{array} \right] `
