c# - 显示月份名称的 DataAnnotation

Question

如何在DataFormatString中显示完整的月份名称和年份？(2014年11月)

我尝试使用这个 DataAnnotation，但它没有给我想要的 o/p:

 [DisplayFormat(DataFormatString="0:MMMM-yyyy")]

Answer 1

我不知道这有没有区别，但是怎么样；

[DisplayFormat(DataFormatString = "{0:MMMM-yyyy}")]

来自 DisplayFormatAttribute.DataFormatString property

The formatting string can be any literal string and usually includes a placeholder for the field's value. For example, in the formatting string "Item Value: {0}", the field's value is substituted for the {0} placeholder when the string is displayed in the DynamicField object. The remainder of the formatting string is displayed as literal text.

If the formatting string does not include a placeholder, the field's value from the data source is not included in the final display text.
