@Html.TextBoxFor(m => m.userCode, new { @readonly="readonly" })

欢迎您为此创建HTML帮助器，但这只是与其他属性一样的HTML属性.您是否会为具有其他属性的文本框创建HTML帮助器?

You are welcome to make an HTML Helper for this, but this is simply just an HTML attribute like any other. Would you make an HTML Helper for a text box that has other attributes?
