C# – Display only date and no time

asp.net-mvcasp.net-mvc-3cdatetime

In MVC razor, I am putting current date in the database like this..

model.Returndate = DateTime.Now.Date.ToShortDateString();

Since the database field is a datetime datatype and I am converting the current date to string format, this is not working.. how can I do this? I am doing the string format because I want the date in mm/dd/yyyy format and not in mm/dd/yyyy hh:mm:ss time format..

EDIT:

In the controller I have

var model = new ViewModel();
model.ReturnDate = DateTime.Now;            
return PartialView("PartialView", model);

In the partialview, I have

@Html.EditorFor(model => model.Returndate)

This is where its displaying the date as Date and Time together… I want just the date to be displayed. Not the time. I hope this edit explains better.

Just had to deal with this scenario myself - found a really easy way to do this, simply annotate your property in the model like this:

[DataType(DataType.Date)]
public DateTime? SomeDateProperty { get; set; }

It will hide the time button from the date picker too.

Sorry if this answer is a little late ;)

C# – Calculate relative time in C#

Jeff, your code is nice but could be clearer with constants (as suggested in Code Complete).

const int SECOND = 1;
const int MINUTE = 60 * SECOND;
const int HOUR = 60 * MINUTE;
const int DAY = 24 * HOUR;
const int MONTH = 30 * DAY;

var ts = new TimeSpan(DateTime.UtcNow.Ticks - yourDate.Ticks);
double delta = Math.Abs(ts.TotalSeconds);

if (delta < 1 * MINUTE)
  return ts.Seconds == 1 ? "one second ago" : ts.Seconds + " seconds ago";

if (delta < 2 * MINUTE)
  return "a minute ago";

if (delta < 45 * MINUTE)
  return ts.Minutes + " minutes ago";

if (delta < 90 * MINUTE)
  return "an hour ago";

if (delta < 24 * HOUR)
  return ts.Hours + " hours ago";

if (delta < 48 * HOUR)
  return "yesterday";

if (delta < 30 * DAY)
  return ts.Days + " days ago";

if (delta < 12 * MONTH)
{
  int months = Convert.ToInt32(Math.Floor((double)ts.Days / 30));
  return months <= 1 ? "one month ago" : months + " months ago";
}
else
{
  int years = Convert.ToInt32(Math.Floor((double)ts.Days / 365));
  return years <= 1 ? "one year ago" : years + " years ago";
}

C# – the difference between String and string in C#

string is an alias in C# for System.String.
So technically, there is no difference. It's like int vs. System.Int32.

As far as guidelines, it's generally recommended to use string any time you're referring to an object.

e.g.

string place = "world";

Likewise, I think it's generally recommended to use String if you need to refer specifically to the class.

e.g.

string greet = String.Format("Hello {0}!", place);

This is the style that Microsoft tends to use in their examples.

It appears that the guidance in this area may have changed, as StyleCop now enforces the use of the C# specific aliases.
