格式化asp.net mvc视图页面

public static class ContollerExtensions
    {
        public static ViewFormatResult ViewFormat(this Controller controller)
        {
            return ViewFormat(controller,null /* viewName */, null /* masterName */, null /* model */);

public abstract class ViewFormatResultBase : ViewResultBase

            TextWriter writer = context.HttpContext.Response.Output;

            ViewContext viewContext = new ViewContext(context, View, ViewData, TempData, writer);

            WriterHtml(writer, viewContext);

            //View.Render(viewContext, writer);

            if (result != null)
            {

            string html = sw.ToString();
            html = Regex.Replace(html, "[\f\n\r\t\v]", "");
            html = Regex.Replace(html, " {2,}", " ");
            html = Regex.Replace(html, ">[ ]{1}", ">");
            string pattern = @"\/\/\<\!\[CDATA\[";
            html = Regex.Replace(html, pattern, "//<![CDATA[\n");
            html = Regex.Replace(html, @"\<\/head\>", "</head>\n");
            html = Regex.Replace(html, @"\<\/body\>", "</body>\n");

            writer.Write(html);
        }
    }

最后调用

public ActionResult Index()
        {
            return this.ViewFormat();
        }
