C# Error reading two dates from a binary file
- by Jamie
Hi all,
When reading two dates from a binary file I'm seeing the error below:
"The output char buffer is too small to contain the decoded characters, encoding 'Unicode (UTF-8)' fallback 'System.Text.DecoderReplacementFallback'. Parameter name: chars"
My code is below:
static DateTime[] ReadDates()
{
System.IO.FileStream appData = new System.IO.FileStream(
appDataFile, System.IO.FileMode.Open, System.IO.FileAccess.Read);
List<DateTime> result = new List<DateTime>();
using (System.IO.BinaryReader br = new System.IO.BinaryReader(appData))
{
while (br.PeekChar() > 0)
{
result.Add(new DateTime(br.ReadInt64()));
}
br.Close();
}
return result.ToArray();
}
static void WriteDates(IEnumerable<DateTime> dates)
{
System.IO.FileStream appData = new System.IO.FileStream(
appDataFile, System.IO.FileMode.Create, System.IO.FileAccess.Write);
List<DateTime> result = new List<DateTime>();
using (System.IO.BinaryWriter bw = new System.IO.BinaryWriter(appData))
{
foreach (DateTime date in dates)
bw.Write(date.Ticks);
bw.Close();
}
}
What could be the cause? Thanks
