Question

Nov 8 1:44

When I use this code, it fails:

string DD = "Nov 8 1:44";

try
{
    DateTime.ParseExact(DD, "MMM dd HH:mm", CultureInfo.InvariantCulture);
}
catch(Exception ex)
{
    MessageBox.Show("Bad day because " + ex.Message);
}

It says,

String was not recognized as a valid DateTime

Please let me know where am I wrong.

Answer 1

That format would be

MMM d H:mm

per the MSDN you need a single d and H due to the fact that your source string is using a single digit day and hour.

“d”

The day of the month, from 1 through 31.

“dd”
