C# string to datetime wrong format output

I'm trying to convert a string into Datetime format this is the my code

CultureInfo culture = new CultureInfo("da-DK");
DateTime endDateDt = DateTime.ParseExact("05-02-2015 15:00", "dd-MM-yyyy HH:mm", culture);
Response.Write(endDateDt);

This is the output result

2/5/2015 3:00:00 PM

The output I'm looking for should be

05-02-2015 15:00

What am I doing wrong?

Let's go more deep..

Response.Write method doesn't have an overload for DateTime, that's why this calls Response.Write(object) overload. And here how it's implemented;

public virtual void Write(Object value)
{
     if (value != null)
     {
          IFormattable f = value as IFormattable;
          if (f != null)
              Write(f.ToString(null, FormatProvider));
          else
              Write(value.ToString());
     }
}

Since DateTime implementes IFormattable interface, this will generate 

f.ToString(null, FormatProvider)

as a result. And from DateTime.ToString(String, IFormatProvider) overload.

If format is null or an empty string (""), the standard format specifier, "G", is used.

Looks like your CurrentCulture's ShortDatePattern is M/d/yyyy and LongTimePattern is h:mm:ss tt and that's why you get 2/5/2015 3:00:00 PM as a result.

As a solution, you can get string representation of your DateTime with .ToString() method and supply to use HttpResponse.Write(String) overload to get exact representaiton.

Response.Write(endDateDt.ToString("dd-MM-yyyy HH:mm", CultureInfo.InvariantCulture));

You are not formatting string representation of the DateTime object. If you haven't specified format then you will get default format based on the current culture.

For getting the desired output you can try this:

endDateDt.ToString("dd-MM-yyyy HH:mm");
