I get model’s values from view with this codeblock and this part is OK.

    var data = new FormData();

    var datas = $(this).serializeArray();
    for (var i = 0; i < datas.length; i++) {
        data.append(datas[i].name, datas[i].value);
    }

In addition I want to add a list to data variable with this code block.

commentlist.push({ CommentID: commentguid, UserName: username, Comment: comment, MainCommentID: topcommentid });
data.append("Comments", commentlist);

And this is the list in my model from controller side.

public List<CommentModalClass> Comments { get; set; }

In summary I want to send commentlist to controllerside in data but I couldn’t make it.
