Hello All,

I'm currently having an issue when evaluating FileInfo.LastWriteTime between two files.  Basically, the two files in question have the IDENTICAL LastWriteTime values, however the following code evaluates to false:

FileInfo f1 = new FileInfo("C:\\FileTest2\\IUS_GEN.MNV");

FileInfo f2 = new FileInfo("C:\\FileTest2\\SubFolder\\IUS_GEN.MNV");

>  Is precision lost when converting to string?

The string you are generating has the time to the nearest second: DateTime is more accurate so yes, precision is lost.

To understand what's happening, you could try formatting with fractions of seconds (e.g. LastWriteTime.ToString("yyyy-MM-dd HH:mm:ss.fffffff").
