问题 Is there a way I can change the default formatting for all DateTime objects to e.g. "dd.MM.yyyy" in Razor ?

问题 I am new to Razor and I want to know how to add one day to model's date object. I need to put a "next day" link Here is the view code <a href="@Html.DisplayNameFor(model => model.date)">Next Day</a> 回答1: You can pass the NextDay as a DateTime in the Model as well using DateTime.AddDays() method.
