有人可以帮我吗，我有以下内容：
@Html.Editor("entities[" + @k + "].Amount", entity.Amount)
我希望编辑器在文本字段中显示金额。我已经尝试过以下方法：
@Html.Editor("entities[" + @k + "].Amount", entity.Amount, new { @Value = "45"}) <text> m</text>
我收到以下错误：
CS1928: 'System.Web.Mvc.HtmlHelper<ProjectName.Order>' does not contain a definition for 'Editor' and the best extension method overload 'System.Web.Mvc.Html.EditorExtensions.Editor(System.Web.Mvc.HtmlHelper, string, string, object)' has some invalid arguments.
有什么建议么？谢谢！
