IContent - I don't have an issue but I understand why.

Hi all,

Why does this works ?

[ContentType(DisplayName = "MyBlock ", GUID = "eccd619a-827c-4b13-b0c8-28c671f0f949", Description = "")]
public class MyBlock : BlockData
    {
        [Ignore]
        public virtual string CmsBlockName
        {
            get
            {
                return (this as IContent).Name;
            }
        }
    }

I looked everywhere and none of the ancestors of MyBlock implements IContent. So why am I able to get the name on the content block by doing this ?

All shared blocks will implement the IContent interface at runtime.
Local blocks won't.

If you call CmsBlockName on a local block, you'll get null reference exception.

I would suggest this code instead:

public static class BlockHelpers
{
    public static string GetName(this BlockData block)
    {
        var content = block as IContent;
        return content?.Name;
    }
}

As Dejan points out is blocks a special kind of content in meaning they can both be a property on other content (local blocks) or be an own instance (shared block). Here is a post that describes how shared blocks are built up.
