Question

I have a BLOG Table with COMMENTS Table with RESPONSES Table.
Example:

• BLOG ONE

  1. COMMENTS=A
     • Response 1
     • Response 2
  2. COMMENT-B
     • Response 1
     • Response 2
     • Response 3

• BLOG TWO

  1. COMMENTS-A
     • Response 1
     • Response 2
     • Response 3
  2. COMMENT-B
     • Response 1
     • Response 2

If we DELETE ‘BLOG TWO’ I need to delete all RESPONSE and all COMMENTS and the BLOG post as well.

I think the solution is to Delete all records returned from a .ToList(). This is what I am thinking/tried. I can seem to do a ‘IN’ list type of command.

ctx.BlogResponse.Where(b => b.blogCommentID = xxMyListItemxxx** ).ForEach(ctx.BlogResponse.DeleteObject);

How do I delete records from/contained within a .ToList()?

Answer 1

I found ‘.DeleteObject’ that deleted items contained within a returned LIST. I was able to do a few calls and it worked fairly well.

ctx.BlogComments.Where(c => c.blogID ==
id).ToList().ForEach(ctx.BlodComments.DeleteObject);

ctx.BlogResponse.Where(c => c.bCommID ==
cID).ToList().ForEach(ctx.BlogResponse.DeleteObject);

The .ForEach is something I haven’t used before and in this case, it works.
