How do I add Head tags in .net using c#

There are of course many tags you can use. Here are a couple to get you started... Also, don't forget to set the Title as well. (this.Header.Title = "this is the title";)

1. keywords
2. description
3. robots
4. date

HtmlMeta metatag = new HtmlMeta();
metatag.Name = "Description";
metatag.Content = "Here's a great description.";
this.Header.Conrols.Add(metatag);

OR, I like it this way...

HtmlMeta metatag = new HtmlMeta(){

   Name = "Description",

   Content = "Here's a great description.",

};

this.Header.Conrols.Add(metatag);
