asp.net中如何动态添加meta tag

asp.net中如何动态添加meta tag?

比如我要动态添加一个 <META NAME="Description" CONTENT="FAQ,dddd,ffff">

[singlepine]

1.添加引用
using System.IO;
using System.Text.RegularExpressions;

2.重写Render
protected override void Render(HtmlTextWriter writer)
{
TextWriter tempWriter = new StringWriter();
base.Render(new HtmlTextWriter(tempWriter));
string meta = "<META NAME=\"Description\" CONTENT=\"FAQ,dddd,ffff\">";
writer.Write(Regex.Replace(tempWriter.ToString(),"</HEAD>",meta,RegexOptions.IgnoreCase));
//原理就是把</head>标签替换为想要加的内容，然后再加上</head>标签，相当于在</head>标签前插入想要加的内容。
}
