Question

I have the following C# that is giving me the error above when trying to parse string to datetime.

DateTime backupdate = System.Convert.ToDateTime(imageflowlabel.Text);   
DateTime currentdate = System.DateTime.Now.AddHours(-2);    
int result = currentdate.CompareTo(backupdate);

imageflowlable.text looks like this 2012-04-15 15:23:34:123

Any ideas on how to convert this?

Thanks

Yes – use “DateTime.ParseExact()” or “TryParseExact()” with a custom format string:

DateTime currentdate;
int result;
try
{
  // EXAMPLE: 2012-04-15 15:23:34:123 
  DateTime backupdate =
     DateTime.ParseExact (
       "yyyy-MM-dd HH:mm:ss:fff", //mind the casing
       imageflowlabel.Text, 
       CultureInfo.InvariantCulture);
  currentdate = System.DateTime.Now.AddHours(-2);    
  result = currentdate.CompareTo(backupdate);
}
catch (Exception ex)
{
