以程式方式加入網頁Head

//My first CSS
HtmlLink myCSS = new HtmlLink();
myCSS.Href = "~/somecss1.css";
myCSS.Attributes.Add("rel", "stylesheet");
myCSS.Attributes.Add("type", "text/css");
Page.Header.Controls.Add(myCSS);

//Here comes my second
myCSS = new HtmlLink();
myCSS.Href = "~/somecss2.css";
myCSS.Attributes.Add("rel", "stylesheet");
myCSS.Attributes.Add("type", "text/css");
Page.Header.Controls.Add(myCSS);

//JavaScript!
HtmlGenericControl myJavaScript = new HtmlGenericControl();
myJavaScript.TagName = "script";
myJavaScript.Attributes.Add("type", "text/javascript");
myJavaScript.InnerText = "alert('Hello');";
Page.Header.Controls.Add(myJavaScript);

//view source code
<link href="somecss1.css" rel="stylesheet" type="text/css" /><link href="somecss2.css" rel="stylesheet" type="text/css" /><script type="text/javascript">alert('Hello');</script>

缺點就是原始碼會串成一大串,很醜
如果在每個header元素加入這行:

Page.Header.Controls.Add(new LiteralControl("\r\n"));

這樣source code就會變的美美地:

<link href="somecss1.css" rel="stylesheet" type="text/css" />
<link href="somecss2.css" rel="stylesheet" type="text/css" />
<script type="text/javascript">
alert('Hello');
</script>
