You should generally be looking for ways to simplify your code (e.g. removing heavily-nested case statements). As a minimum, look for the most complicated method you have and check whether it needs simplifying.
In Visual Studio, there is built-in support for Cyclomatic Complexity analysis.

- Look at the function with the largest Cyclomatic Complexity number and consider refactoring to make it simpler.
Figure: Results from cyclomatic analysis (and other analyses) give an indication of how complicated functions are
Tip: Aim for "green" against each function's Maintainability Index.
