Run StyleCop.Console.exe -project-path "path/to/your/cs/project" to get a static code analysis with StyleCop's default rules.

To not analyse subdirectories recursively add the argument switch -not-recursively.

To deactivate default rules, edit the file Settings.StyleCop with the StyleCopSettingsEditor.exe or pass your existing settings file via command line argument:

StyleCop.Console.exe -settings-location "path/to/your/Settings.StyleCop" -project-path "path/to/your/cs/project"

You can add your own rules by adding your own SourceAnalyzer class in the StyleCop.Rules project. Refer to the existing RulesAnalyzer.cs class as a real-life example for disallowing more than one class per code file.
