ASP.net C# New line

Question

I need help with making a line break. I have this code:

<asp:Repeater runat="server" ID="rptPosts">
    <ItemTemplate>
        <h2><%#Server.HtmlEncode(Eval("post_title").ToString()) %></h2>
        <em><%#Server.HtmlEncode(Eval("post_posted").ToString()) %></em>
        <br />
        <%#Server.HtmlEncode(Eval("post_content").ToString()) %>
    </ItemTemplate>
</asp:Repeater>

I want to make post_content generate automatic new lines. I've tried with environment.newline but I can't seem to get it to work.

EDIT:
I mean to generate HTML breaks. Like nl2br() in PHP.

You need to do it after you have HTML encoded it. Otherwise any HTML you put in will end up getting encoded. So your best bet is:

Server.HtmlEncode(Eval("post_content").ToString())
    .Replace(Environment.NewLine, "<br>"+Environment.NewLine)

This will encode everything as normal and then everywhere it finds a new line it will replace it with a <br> tag (line break in HTML) and then the new line again (to make sure you keep the plain text line breaks as well as the HTML ones.

This isn't making "post_content generate automatic new lines" but I'm not too clear on what that means since post_content is just a key in whatever your data item is. If this is not adequate you'll have to clarify your requirements a bit more.
