在ASP.NET MVC中将客户端日期时间转换为服务器日期时间

Question

I have a simple model like:

[MyRequired(Error = "Invalid date time")]
public DateTime LastUpdate
{
   get;set;
}

...

and MyRequiredAttribute class:

public class MyRequiredAttribute: RequiredAttribute {
   public override IsValid(object value) {
        //value get from request is `01/01/0001 00:00:00 ...`
        DateTime parsedTime = DateTime.Parse(value.ToString());

        // here throws exception
   }
}

and on Javascript side, using Datepicker plugin, I used

<input type="text" id="LastUpdate" name="LastUpdate" class="datepicker" value="<%=DateTime.Now.ToString( "dd-MM-yyyy" )%>" />

and

$(".datepicker").datepicker({ dateFormat: 'dd-mm-yy' });

Every time, I receive from request 01/01/0001 value and throws an error that format is not correct.

How can I convert from dd-MM-yyyy format to MM/dd/yyyy format ? Maybe MVC accepts only MM/dd/yyyy format.

Answer 1

In your Model use following way

public string LastUpdate
{
  get;set;
}

Now in your Controller Bind following way if it is in Editing Mode than

Model.LastUpdate = FetchDateFromServer.ToString("dd-MM-yyyy")

otherwise

Model.LastUpdate = DateTime.UtcNow.ToString("dd-MM-yyyy")

Now from your View Remove value from input type="text" it will take if it is strongly typed

<input type="text" id="LastUpdate" name="LastUpdate" class="datepicker" />

I hope it will work as it is perfectly working in my project

Answer 2

I think you should write

$("#dates").datepicker("option", "dateFormat", "dd-mm-yy");   // it will give format dd-mm-yy

or

$("#dates").datepicker("option", "dateFormat", "mm-dd-yy"); // it will give format mm-dd-yy

Insted of

$(".datepicker").datepicker({ dateFormat: 'dd-mm-yy' });

or on server side You can do something like this

const string dateformate = "dd/MM/yyyy";
var reachDate = DateTime.ParseExact(dates, dateformate, CultureInfo.InvariantCulture);

This will convert any date to dd/MM/yyyy format.
