使用asp.net更新MongoDB中的子文档 [英] Update sub document in MongoDB using asp.net with example

问题描述

现在我正在使用ASP.NET中的MongoDB，刚刚阅读了一篇文章，其中有一篇博客文章示例，并提到了以下步骤来更新评论（子文档）。

博客被拍成了主要文件

评论被视为子文档并与主文档一起发布

当我们需要向特定博客插入新评论时，我们是获取现有博客文档，在前端添加新评论（子文档）并再次使用博客ID更新博客文档。

如果是这样的话，让我们采取非常受欢迎的博客场景评论被发布到博客上。如果必须发布任何新评论，我们需要从DB服务器获取所有现有评论到Web服务器，因此它会增加网络流量。

这是一般情况还是有其他替代方式向子文档添加新内容？意思是，我需要一个功能，只需在现有文档中插入新值。

Right now I am working on MongoDB in ASP.NET and just gone through an article in which it has taken a blog post example and mentioned the following steps to update comments (sub document).
The blog was taken a main document
Comments were taken as sub document and posted along with main document
When we need to insert a new comment to a particular blog, we are getting the existing blog document, adding new comment (sub document) in front-end and again updating the blog document with blog ID.
If it is the case, let us take very popular blog scenario where thousands of comments were posted to a blog. If any new comment has to be posted, we need to get all the existing comments from DB server to Web server as a result it will increase network traffic.
Is this general scenario or is there any alternative way to add new content to sub document? Means, I need a functionality which should just insert new values in existing document.
