I am n开发者_运维知识库ew to MVC and i want to know how to create custom tags in asp.net MVC?

Maybe something like this:

        {
            TagBuilder tag = new TagBuilder(tagName);
            tag.SetInnerText(innerText);
            tag.MergeAttributes<string, string>(attributes);
            return MvcHtmlString.Create(tag.ToString());
        }
    }

@Html.MyTag("custom", "Text", attributes)
