c# - Linq to EF Include sub List for List -

given following method returns blogpost, parent blog object , list of comments blog post; trying determine if there way, within method, return list of comment replies each comment within list of comments.

here classes

public class comment {     [key]     public int commentid { get; set; }      //[foreignkey("blogpost")]     //[index("ix_blogpostindex", 1, isclustered = false, isunique = false)]     public int blogpostid { get; set; }      public blogpost blogpost { get; set; }      [required]     public string commenttext { get; set; }     [required]     public datetime commentposttime { get; set; }      public list<reply> commentreplies { get; set; }       [required]         public string userfullname { get; set; } }   public class reply {     [key]     public int replyid { get; set; }      [required]     public string replytext { get; set; }      [required]     public userprofile memberprofile { get; set; }      [foreignkey("comment")]     [index("ix_commentindex", 1, isclustered = false, isunique = false)]     public int commentid { get; set; }      public comment comment { get; set; }    [required]     public datetime replyposttime { get; set; }   } 

and method

public blogpost getblogpostbyid(int blogpostid) {     return _db.blogposts.where(e => e.blogpostid == blogpostid)                         .include(e => e.comments)                         .include(e => e.blog)                         .firstordefault(); } 

i can iterate through return object method , retrieve replies sure there must way, using linq, within method part of returned object rather run method so.

if "replies" navigation property on comments, can add include existing query:

.include("comments.replies") 

this works same way includes have, easier include nested navigation properties
