MVC3 DateTime属性的默认值 [英] MVC3 Default value for a DateTime property

问题描述

我在一个Model类上有一个DateTime属性，并希望将其默认值设置为Now。以下代码是我希望可以运行但无法编译的代码。它不喜欢System.DateTime.Now调用：

I have a DateTime property on one of my Model classes and want to set it's default vaule to Now. The below code is what I had hoped would work but won't compile. It doesn't like the System.DateTime.Now call:

    [DisplayFormat(DataFormatString = "{0:d}", ApplyFormatInEditMode = true)]
    [Display(Name = "To Date")]
    [Required(ErrorMessage = "To Date is required.")]
    [DefaultValue(System.DateTime.Now)]
    public DateTime DateTo { get; set; }

有什么想法吗？

推荐答案

在模型类中：

private DateTime _date = DateTime.Now;
public DateTime Date 
{
  get { return _date; }
  set { _date = value; }
}
