Sitefinty：按博客ID获取博客类别

Question

I want a list of all categories, which are associated with one or more blogs. I am able to get the list of all the blogs and blog ids. How can I get category id by blog id associated with that blog .

BlogsManager blogsManager = BlogsManager.GetManager();
var bb = blogsManager.GetBlogPosts()
                     .Where(b => b.Status == ContentLifecycleStatus.Live) 
                     .ToList();

foreach (var blogItem in bb)
{
    var blogID = blogItem.Id ;
    //get Category ID here 
}

Make sure you have the following using statements in your control or page:

using Telerik.OpenAccess;
using Telerik.Sitefinity.GenericContent.Model;
using Telerik.Sitefinity.Model;
using Telerik.Sitefinity.Modules.Blogs;
using Telerik.Sitefinity.Taxonomies;

I've modified your above code to get the categories assigned to each post:

BlogsManager blogsManager = BlogsManager.GetManager();
var bb = blogsManager.GetBlogPosts()
                     .Where(b => b.Status == ContentLifecycleStatus.Live)
                     .ToList();

foreach (var blogItem in bb)
{
    var blogID = blogItem.Id;
    var categoryIds = blogItem.GetValue<TrackedList<Guid>>("Category");

    var taxonomyManager = TaxonomyManager.GetManager();

    foreach (var catId in categoryIds)
    {
        var taxon = taxonomyManager.GetTaxon(catId);

        var id = taxon.Id;
        var name = taxon.Name;

    }
}
