asp.net-mvc-4 - Time Input Field in ASP.NET MVC

Question

I'm having trouble trying to write a form with time field using ASP.NET MVC 4.

Model:

class Abcde {
    [DataType(DataType.Time)]
    public DateTime ATime { get; set; }
}

View.cshtml

...
@Html.EditorFor(m => m.ATime)
@Html.ValidationMessageFor(m => m.ATime)

The validation always failed when I tried to input a time (hh:nn:ss), and said it was not in the corrent format, so i have to input a date instead. My Question is should I change the type to TimeSpan? Or is there any other way?

Answer 1

[Required]
[DataType(DataType.Time)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:H:mm}")]
public DateTime Time { get; set; }`

试试这个，你可以按照你希望它为你工作的方式格式化 DataFormatString，我现在在一个项目中使用它，它对我有用。

Answer 2

实际上，这对我有用。

[DataType(DataType.Time)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:HH:mm}")]
public DateTime Hour { get; set; }

Answer 3

[Required]
[DataType(DataType.Time)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:HH:mm}")]
public DateTime Time { get; set; }

这段代码是正确的。但它仅在您使用EditorFor而不是TextBoxFor.

Answer 4

利用：

[Required]
[DataType(DataType.Time)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:HH:mm:ss}")]
public DateTime FieldTime{ get; set; }

您需要将您的日期验证与此注释在内部工作的格式相匹配。因此，添加传递字符串模式的 ApplyFormat 即可获得它。
