DataType.MultilineText不接收MultilineText.cshtml模板

Question

我有这样的模式视图，可以在其中设置属性的DataType注释。

AnyVal

Shared \ EditorTemplates文件夹包含这些模板。

 public class Contact
    {
        [Required]
        [Display(Name = "Your email address", Prompt = "Your email address")]
        [DataType(DataType.EmailAddress)]        
        public string Email { get; set; }

        [Required]
        [Display(Name = "Your question, suggestion or feedback...", Prompt = "Your question, suggestion or feedback...")]
        [DataType(DataType.MultilineText)]        
        public string Message { get; set; }

        [Display(Name = "Your file", Prompt = "Your file")]
        [DataType(DataType.Upload)]        
        public HttpPostedFileBase File { get; set; }
    }

Object.cshtml模板用于将模型属性解析并将其重定向到其实际模板。

EmailAddress.cshtml
Upload.cshtml
MultilineText.cshtml
Object.cshtml

最后的代码是实际的View文件

@model dynamic

@foreach (var prop in ViewData.ModelMetadata.Properties.Where(p => p.ShowForEdit))
{
    if (prop.TemplateHint == "HiddenInput")
    {
        @Html.Hidden(prop.PropertyName)
    }
    else
        @Html.Editor(prop.PropertyName)
}

已成功选择并应用EmailAddress.cshtml和Upload.cshtml模板，但通过MultilineText.cshtml在属性上设置了MultilineText.cshtml，但没有成功。有什么想法吗？
