开发自定义web控件时把css，js嵌入成资源

1设置文件的属性：生成操作--》嵌入的资源

2在AssemblyInfo.cs中添加

　　[assembly: WebResource("程序集名.文件名", "类型")] 如：

　　[assembly: WebResource("HelloWorld.SH.css","text/css")]
　　[assembly: WebResource("HelloWorld.SH.js", "text/javascript")]

3重写控件类的OnPreRender，添加引用代码　　

　　　　string cssUrl = Page.ClientScript.GetWebResourceUrl(this.GetType(), "HelloWorld.SH.css");
            HtmlLink cssLink = new HtmlLink();
            cssLink.Href = cssUrl;
            cssLink.Attributes.Add("rel", "stylesheet");
            cssLink.Attributes.Add("type", "text/css");
            this.Page.Header.Controls.Add(cssLink);
            this.CssClass = "divHW";

            string jsUrl = Page.ClientScript.GetWebResourceUrl(this.GetType(), "HelloWorld.SH.js");
            Page.ClientScript.RegisterClientScriptInclude("SH", jsUrl);
