Hello
when I run the ExampelsWPFFileTransfer Demo, Encounter some errors when I transfer files。Specifically When the file is very small, such as 1k,2k. Can you give me some help ， ThanksRegards,
msdc1231. Is the error 100% reproducible?
2. What is the exact size of the file you are using to create the problem?
3. Can you provide any more information regarding the error?Regards,
MarcHello
Thanks.
1. not 100%. but when the file is 1k,almost 30%.
2. I tested several times。 I meet the condition when the file size is 1K,20K
3. such as the file size is 35112 . the received file size is 35000.4、in MainWindow.xaml，If i set sendChunkSizeBytes = 500000000 ;
It almost ok.5、 I guess when i send data use
connection.SendObject(“PartialFileData”, streamWrapper, customOptions, out packetSequenceNumber);if the streamwrapper’s data too small,will lead some mistake.
6、in log file ,I didn’t find any related message.
best regards
Hello
I think I have solved the problem.
I change the code in MainWindow.xaml.cs
public void AddData(long dataStart, int bufferStart, int bufferLength, byte[] buffer)
{
lock (SyncRoot)
{
data.Seek(dataStart, SeekOrigin.Begin);
data.Write(buffer, (int)bufferStart, (int)bufferLength);ReceivedBytes += (int)(bufferLength – bufferStart);
//add
if (ReceivedBytes == SizeBytes)
{
data.Flush();
}
}NotifyPropertyChanged(“CompletedPercent”);
NotifyPropertyChanged(“IsCompleted”);
}Now It’s OK
Best regards

Yea, that seems like the sort of thing it might be. Many kind thanks for the fix. I have updated the repository and online example.
