How to get all analyzers rules in a solution

I have added some analyzer via NuGet in my solution. How to get all added analyzer rules from NuGet references? I need the ID (e.g. CA1001) and descriptions of all my enabled analyzers.

EDIT: I need some C# code to do this.

You can view the diagnostics produced by your project's analyzers in the "Dependencies" tree:

enter image description here

You can adjust the level (none, suggestion, warning, error, etc) via the context menu on these leaf nodes.

Alternatively, if you are using VS16.10 (released very recently) there is a new .editorconfig editor which includes a tab that shows all analyzers:
