动态添加< p>在asp.net中标记评论系统 [英] dynamically add <p> tag in asp.net for comment system

问题描述

我正在为我的网页添加一个评论框， 我设计了表单来接受用户名和注释，并将其存储在数据库表中.我不知道如何在页面上呈现该数据.在表上进行迭代，然后在页面上创建段落，或者在页面上创建标签.

I am making a comment box for my webpage, I have designed the form to take the user Name and comments and store it in the database table. I don't know how to render that data on the page. Either by iterating on the table and subsequently creating paragraph on the page or by creating labels on the page.

我在C#中使用LINQ to SQL. 请告诉我如何在网页上的数据库或教程的某些链接中呈现注释.

I am using LINQ to SQL in C#. Please tell me how to render the comments in database on web page or some link to tutorial

推荐答案

让我们假设您有一个CommentsTable具有列:

let's assume you have a CommentsTable having columns:

• id int
• 用户名varchar(50)
• 评论nvarchar(5000)
• DateCreated DateTime

并且您的LinqToSql数据上下文是myDataContext，您可以执行以下操作:

and your LinqToSql data context is myDataContext thn you can do this:

myDataContext db = new myDataContext();
var commentsData = db.CommentsTable.ToList();

string html=string.Empty;
foreach(var item in commentsData)
{
   html+="<div class='property-row'><div class='username'>"+item.Username+"</div>";
   html+="<div class='notice'>"+item.DateCreated.ToString("mm-dd-yyyy hh:mm")+"</div>"
   html+="<div class='comment'>"+item.Comment+"</div>";
}

Div1.InnerHtml= html;

现在，您可以通过适当装饰设计器中的类来控制部分的外观，即用户名行及其下方的注释 即

now you can control look of your sections i.e. username row and the comments beneath it by suitably decorating the classes on the designer i.e.

.property-row
{
    position:relative;
    width:100%;
    background-color:#CCCCCC;
    border:1px solid Black;
}
.username
{
   position:relative:
   padding:2px;
   top:2px;
   font-size:0.8em;
   color:#333333;
   text-decoration:underline;
}
.comment
{
   position:relative;
   padding:2px;
   margin:2px;
   font-size:1em;
   color:black;
}
.notice
{
   font-size:0.7em;
}
