输入字符串格式不正确

我需要一些关于标题中显示的错误的帮助，我的代码如下所示。错误是出现在这条线：输入字符串格式不正确

@Html.EditorForModel()

代码：

@model Assignment2.Models.Order 

@{ 
    ViewBag.Title = "Address And Payment"; 
} 



<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> 
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> 

@using (Html.BeginForm()) 
{ 

    <h2>Address And Payment</h2> 
    <fieldset> 
     <legend>Shipping Information</legend> 

     @Html.EditorForModel() 
    </fieldset> 
    <fieldset> 
     <legend>Payment</legend> 
     <p>We're running a promotion: all tickets free with the promo code: "FREE"</p> 

     <div class="editor-label"> 
      @Html.Label("Promo Code") 
     </div> 
     <div class="editor-field"> 
      @Html.TextBox("PromoCode") 
     </div> 
    </fieldset> 

<input type="submit" value="Submit Order" /> 
}

什么是异常的堆栈跟踪？ – svick 2012-04-15 13:58:17

你的模型（'Assignment2.Models.Order'）看起来像什么？ – nemesv 2012-04-15 14:05:49

您的PostalCodeRequiredAttribute的错误消息不必要{：

[Required(ErrorMessage = "Please enter {Postal Code")]

删除它，它应该工作。

您得到了例外，因为框架使用ErrorMessage作为format string，并且一个未关闭{这是无效的。
