Question

I’ve got the following Stream code . and I feel that it’s really old and ugly and that there should be a cleaner way to do this.

// Write the current chunk to the stream.
using (var fileStream = new FileStream(tempPath, currentChunk == 0 ? 
                                                     FileMode.Create : 
                                                     FileMode.Append))
{
    var buffer = new byte[uploadedFile.Length];
    uploadedFile.Read(buffer, 0, buffer.Length);
    fileStream.Write(buffer, 0, buffer.Length);
}

What is it doing?

I upload a file in chunks. So we either create a new file (when we’re at the first chunk, ie chunk == 0) .. or we append the chunk data to an existing file.

I feel that the 3 lines are obsolete and there’s a better method that’s available to be used.

Yes / No / Maybe?

EDIT: .NET 4.0 is fine by me 🙂

Might Stream.CopyTo work for you?

For what it’s worth, though, I don’t think this API existed until .NET 4.0.
