将页基中的代码添加到c#头文件中

我有以下代码在我的MasterPageBase.cs文件:

        protected override void OnLoad(EventArgs e)
    {
        string url = Request.Path;
        var page = _ContentPageRepository.GetContentPageByUrl(url, ConfigurationManager.GetSiteID());
        if (page != null)
        {
            PageBase.SetTitle(page.Title);
            PageBase.SetDescription(page.Description);
            PageBase.SetKeywords(page.Keywords);
        }
        else
        {
            this.ProcessSiteMap();
        }
        this.AddGACode(); 
        base.OnLoad(e); 
    }

我需要将this.AddGACode();添加到页面的头部部分，但是当我在运行解决方案时查看页面的源代码时，我看到这是将其添加到页面的主体部分。

我试过Page.Header.Controls.Add(AddGACode());，得到以下错误:The best overloaded method match has some invalid arguments和cannot convert from 'void' to 'System.Web.UI.Control'

我怎么做才能把这段代码添加到头部?TIA

编辑:请求查看AddGACode方法:

        private void AddGACode()
    {
        var gaCode = SiteManager.GetSite().GoogleAnalyticsCode;
        if (!String.IsNullOrEmpty(gaCode) && Response.StatusCode == 200)
        {
            if (!ConfigurationManager.EnableUniversalGATracking)
            {
                ClientScriptManager cs = Page.ClientScript;
                StringBuilder csText = new StringBuilder();
                csText.Append("<script type='"text/javascript'">");
                csText.Append(String.Format("var _gaq = _gaq || []; _gaq.push(['_setAccount', '{0}']); ", gaCode));
                csText.Append("_gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })();");
                csText.Append("</script>");
                cs.RegisterClientScriptBlock(GetType(), "GACode", csText.ToString());
            }
            else
            {
                ClientScriptManager cs = Page.ClientScript;
                StringBuilder csText = new StringBuilder();
                csText.Append("<!-- Universal GA Code --><script type='"text/javascript'">");
                csText.Append(String.Concat("(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o), m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); ga('create', '", gaCode,  " ', 'auto'); ga('send', 'pageview');"));
                csText.Append("</script>");
                cs.RegisterClientScriptBlock(GetType(), "GACode", csText.ToString());
            }
        }
    }

编辑:

这段代码在AddGACode方法中。页面的OnLoad中仍然有this.AddGACode();，似乎与此编辑复制了代码，但如果我从OnLoad中删除this.AddGACode();，这两个代码将消失

ClientScriptManager cs = Page.ClientScript;
StringBuilder csText = new StringBuilder();
csText.Append("<!-- Universal GA Code --><script type='"text/javascript'">");
csText.Append(String.Concat("(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o), m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); ga('create', '", gaCode,  " ', 'auto'); ga('send', 'pageview');"));
csText.Append("</script>");
cs.RegisterClientScriptBlock(GetType(), "GACode", csText.ToString());
LiteralControl lc = new LiteralControl(csText.ToString());
Page.Header.Controls.Add(lc);

        LiteralControl lt = new LiteralControl("<script type='text/javascript'>alert('test');</script>");
        Header.Controls.Add(lt);

LiteralControl lt = new LiteralControl(AddGACode());
Header.Controls.Add(lt);
