解决方法
您可以使用
[DataType(DataType.MultilineText)]属性来装饰模型属性：
模型：@H_403_7@
public class MyModel
{
[DataType(DataType.MultilineText)]
public string MyProperty { get; set; }
}
控制器：@H_403_7@
public class HomeController : Controller
{
public ActionResult Index()
{
return View(new MyModel());
}
}
视图：@H_403_7@
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<SomeNs.Models.MyModel>" %>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<%: Html.EditorForModel() %>
</asp:Content>
