Solution 1

There isn't any difference. String.Format("{0:g}", dt) will actually call dt.ToString("g")

DateTime implements the IFormattable[^] interface, and String.Format will end up calling the IFormattable.ToString[^] method.

Hi Mo, Thanks for your response, In dt.Tostring() I can pass the cultureInfo.currentculture or Invarientculture... how this works with String.Format("{0:g}",dt)

There is also a String.Format[^] method which allows you to pass a IFormatProvider.

Hi I tried this program,
class Program
{
static void Main()
{
DateTime dt = DateTime.Today;
Console.WriteLine(string.Format("{0:g}", dt));
Console.ReadLine();
Console.WriteLine(dt.ToString(CultureInfo.CurrentCulture));
Console.ReadLine();
Console.WriteLine(dt.ToString(CultureInfo.InvariantCulture));
Console.ReadLine();
}
}
I got the output as
1/13/2014 12:00 AM
1/13/2014 12:00:00 AM
01/13/2014 00:00:00
if string.format and .Tostring("g")
is same then the output is different. Am I missing something here? Sorry to ask again and again.

String.Format("{0:g}", dt) is the same as dt.ToString("g"). That's not the same as dt.ToString(CultureInfo.CurrentCulture). You'll be looking for dt.ToString("g", CultureInfo.CurrentCulture)

Thanks Mo. I think i am clear now.
