Problems with CultureInfo

Question

Hello there,

I've got a problem using the UnixFileParser when the CultureInfo of the System is different to en-US.

The Name of the month in ParseExact throws an exception "unable to parse DateTime" as my System is running in CultureInfo "de-DE".

I had to add these line:
IFormatProvider culture = new CultureInfo("en-US", true);

My actual code looks now like:

// next 3 are the date time
         int dateTimePos = index;
         System.DateTime lastModified;
         System.Text.StringBuilder stamp = new System.Text.StringBuilder(fields[index++]);
         stamp.Append('-').Append(fields[index++]).Append('-');
         
         string field = fields[index++];

         // Force use of "en-US"
         IFormatProvider culture = new CultureInfo("en-US", true);

         if (field.IndexOf((System.Char) ':') < 0)
         {
            stamp.Append(field); // year

            // Force use of "en-US"
            lastModified = DateTime.ParseExact(stamp.ToString(), format1, culture, DateTimeStyles.None);
         }
         else
         {
            // add the year ourselves as not present
                int year = CultureInfo.CurrentCulture.Calendar.GetYear(DateTime.Now);
            stamp.Append(year).Append('-').Append(field);

            // Force use of "en-US"
            lastModified = DateTime.ParseExact(stamp.ToString(), format2, culture, DateTimeStyles.None);
            
            // can't be in the future - must be the previous year
            if (lastModified > DateTime.Now)
            {
                    lastModified.AddYears(-1);
            }
         }

Now everything works fine for me.
Maybe there other users encounter similar problems.
