    You could define your meta tag as a static string like so:

    Private Shared MetaLanguage As String =
    String.Format("<meta http-equiv=""Content-Language"" content=""{0}""/>", CultureInfo.CurrentUICulture.TwoLetterISOLanguageName)

    Then place them in your head like so:

    <head runat="server">
    <%=MetaLanguage%>
</head>

    This allow you to use any meta tag values and is easy to read and customize. Note: The use of the Shared keyword (static) helps improve performance.

    Or you could just put your meta-tag in the header, with an ID and a runat="server"... then in the code behind say

    myMetaTag.Content = "noindex,follow";

    or

    myMetaTag.Visible = false;

    or whatever you'd like.

    I think this is the best approach:

    this.Page.Header.Controls.Add(new LiteralControl(@"<meta ... />"));

    Enjoy!

    MetaDescription = "Your meta description goes here"; MetaKeywords = "Keyword1,Keyword2,Keyword3";

    OK... I actually only use C#... Or HTML into C#. I never use codebehind, designer or webcontrols in the file aspx... So I program everything from classes... And dynamically.

    Result:

    HtmlMeta meta = new HtmlMeta();
meta.Name = "robots";
`meta.Content = "Here is what you want";`
var page=HttpContext.Current.Handler as Page;
page.Header.Controls.Add(meta);

    Try moving whatever it is that you are doing in the <% .... %> to the code-behind. If you are using the script to add content into the page, you can replace it with an asp:Literal control and then set the value you were previously calculating in the script block to the code-behind and set Literal.Text to that value.
