Asp.net 后台添加CSS、JS、Meta标签

下面是从Asp.net 后台添加CSS、JS、Meta标签的写法，我们这里写成函数方便以后使用。如果函数放在页面类中， Page参数也可以不要。
首先导入命名空间 using System.Web.UI.HtmlControls;

/// <summary>
/// 添加JS脚本链接
/// </summary>
/// <param name="page">页面</param>
/// <param name="url">路径</param>
public void AddJS(System.Web.UI.Page page, string url)
{
HtmlGenericControl jsControl = new HtmlGenericControl("script");
jsControl.Attributes.Add("type", "text/javascript");
jsControl.Attributes.Add("src", url);
page.Header.Controls.Add(jsControl);
}
/// <summary>
/// 添加JS脚本内容
/// </summary>
/// <param name="page">页面</param>
/// <param name="content">脚本内容</param>
public void AddScript(System.Web.UI.Page page, string content)
{
HtmlGenericControl scriptControl = new HtmlGenericControl("script");
scriptControl.Attributes.Add("type", "text/javascript");
scriptControl.InnerHtml = content;
page.Header.Controls.Add(scriptControl);
}
/// <summary>
/// 添加CSS样式链接
/// </summary>
/// <param name="page">页面</param>
/// <param name="url">路径</param>
public void AddCss(System.Web.UI.Page page, string url)
{
HtmlLink link = new HtmlLink();
link.Href = url;
link.Attributes.Add("rel", "stylesheet");
link.Attributes.Add("type", "text/css");
page.Header.Controls.Add(link);
}
/// <summary>
/// 添加CSS样式内容
/// </summary>
/// <param name="page">页面</param>
/// <param name="content">样式内容</param>
public void AddStyle(System.Web.UI.Page page, string content)
{
HtmlGenericControl styleControl = new HtmlGenericControl("style");
styleControl.Attributes.Add("type", "text/css");
styleControl.InnerHtml = content;
page.Header.Controls.Add(styleControl);
}
/// <summary>
/// 添加Meta标签
/// </summary>
/// <param name="page">页面</param>
/// <param name="name">Meta名字</param>
/// <param name="content">Meta内容</param>
public void AddMeta(System.Web.UI.Page page, string name, string content)
{
HtmlMeta meta = new HtmlMeta();
meta.Name = name;
meta.Content = content;
page.Header.Controls.Add(meta);
}
