使在ASP淨MVC自定義幫助更好的辦法

Question

我只是寫在ASP淨MVC 3自定義的MVC助手和它的作品..但它看起來並不好：

public static MvcHtmlString BsCheckBox<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression) 
    { 
     string fieldName = ExpressionHelper.GetExpressionText(expression); 
     ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, html.ViewData); 


     return MvcHtmlString.Create(
      "<input type=\"checkbox\" name=\"" + fieldName+ "_cb\" " + (metadata.Model.ToString() == "S" 
       ? "checked='checked'" 
       : "") + "/>" + 
        "<input type=\"hidden\" name=\"" + fieldName + "\" value=\"" + metadata.Model.ToString() + "\" />" 
      ); 
    } 

此幫助創建了兩個輸入標籤元素來控制複選框。 「S」== true 「N」== false

還有更好的方法來寫同樣的東西嗎？

編輯：

的TagBuilder顯得有些冗長：

string campo = ExpressionHelper.GetExpressionText(expression); 
     ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, html.ViewData); 

     TagBuilder element1 = new TagBuilder("input"); 
     element1.MergeAttribute("type","checkbox"); 
     element1.MergeAttribute("name", campo + "_cb"); 
     if (metadata.Model.ToString() == "S") 
      element1.MergeAttribute("checked", "checked"); 

     TagBuilder element2 = new TagBuilder("input"); 
     element2.MergeAttribute("type", "hidden"); 
     element2.MergeAttribute("name", campo); 
     element2.MergeAttribute("value", metadata.Model.ToString()); 

     return MvcHtmlString.Create(element1.ToString() + element2.ToString());

使用TagBuilder：http://www.asp.net/mvc/tutorials/using-the-tagbuilder-class-to-build-html-helpers-cs
