【问题描述】:
我使用 EF4.1 和代码先创建一个数据库。
我的模型在 mvc3 中看起来像这样
public class BusinessContactDetailsModel
{
public int Id { get; set; }
[Display(Name = "Contact Date")]
public DateTime ContactDate { get; set; }
[Range(1, 5)]
[Display(Name = "Outcome Rating")]
public int OutcomeRating { get; set; }
[DataType(DataType.MultilineText)]
public string Comment { get; set; }
public int BusinessId { get; set; }
[Display(Name = "Method of Contact")]
public int FormOfContactId { get; set; }
[Display(Name = "Follow up Date")]
public DateTime FollowUpDate { get; set; }
}
当我在构建过程中尝试运行应用程序时失败。我知道它的 FollowUpProperty 导致了问题,因为它是我刚刚添加的一个新属性,奇怪的是如果我将属性从 DateTime 更改为 Int 它可以正常工作。
有其他人遇到过这种问题吗?
我的堆栈跟踪看起来像

原来是因为 DateTime 不可为空。我将其更改为允许空日期,现在可以正常工作了。
