SharePoint writing content to a site navigation programmatically

For a certain sub site in sharepoint I wa开发者_运维技巧nt to add a new section to the navigation on the left handside. For example "My Section". Under "My Section" I wish to some links but I want to control the hml output of the links. For example add my own classes. How would I go aboutdoing this?

There are actually two questions here:

1. How to create menu items programmatically. The answer is here: http://itfootprint.wordpress.com/2007/08/07/adding-menu-items-navigation-to-sharepoint-site/

2. How to display the items you have added in a different manner. To do this, you have to customize the ASP.Net code that accesses the QuickLaunch navigation. Hints could be found here:
