In PHP it is simple and we have:
echo '<h3><a href="#"> text</a><h3></h3></h3>';
but in asp.net C# code behind we can use similar way
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Response.Write("<h3><a href="#"> text</a><h3></h3></h3>");
}
}
