使用editorformodel()时,如何修饰ASP.NET MVC ViewModel属性以呈现为文本区域

您可以用 [DataType(DataType.MultilineText)] 属性:

模型:

public class MyModel
{
    [DataType(DataType.MultilineText)]
    public string MyProperty { get; set; }
}

控制器:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyModel());
    }
}

观点:

<%@ 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>

创建文本区域模板,然后用 UIHint("TextArea") attribute .
