1) //Saving post content in database as html

public ActionResult Edit(Post post, FormCollection obj)
        {               
          post.Content = Server.HtmlEncode(post.Content);
        }

2) //Displaying post content to view

<%: System.Web.HttpUtility.HtmlDecode(item.Content)%>

OR

<%: item.Content%>

MVC3/Razor:

@Html.Raw(item.Content)

MVC2/WebForms:

<%: MvcHtmlString.Create(item.Content) %>
