Hello,

I have a question regarding the chunks and the byte[].
I believe you have to save each chunk seperately to the database. Am I correct?

Is there a way to collect each chunk in memory as a byte[] and when the last chunk is uploaded, the byte[] can be saved as a whole?

The reason is the following:
I want to upload a file (big file) and save it to the database in a Filestream column along with some additional metadata. The actions to save it all in the database should be in 1 call on the server so it can be placed in a transaction.
I think it is impossible to do this by overriding the savechunkdata?

Is there a workaround or am I missing something?

thanks in advance

Hi Sodi We,

You shoul override the SaveChunkData and inside it check when the last chunk is uploaded. After the last chunk is uploaded you can save the file in your data-base. Finally you can delete the file from the file-system. Your code shoul look something like:

public override bool SaveChunkData(string filePath...)

{

bool result = base.SaveChunkData(filePath...);

if (this.IsFinalFileRequest())

{

if (result)

{

// save file into your data-base

}

// delete the file from file system:

this.RemoveFile(filePath);

}

Please give it a try and let us know if you have more question.

Kind regards,
