How to Delete Categories
You can delete categories from a base catalog or a virtual catalog by using the DeleteCategory method of the ProductCatalog object. This method deletes the category from the catalog but does not delete any child categories or products under it.
This method does not delete the category from the catalog database. You must use the PurgeDeletedItems method to remove the category from the catalog database.
To delete a category from a catalog
Get the catalog that contains the category to be deleted.
Delete the category by using the DeleteCategory method.
Example
This example demonstrates how to delete a category from a base catalog. The base catalog "Books" has a category "Autobiography."
public static void DeleteCategory(CatalogContext context)
{
// Get the "Books" catalog.
ProductCatalog catalog = context.GetCatalog("Books");
// Delete the category "Autobiography."
Catalog.DeleteCategory("Autobiography");
}
