Sharepoint UploadFile 'Specified argument was out of range of valid values'

Question

I'm trying to duplicate a file from one library to another within a Remote Event Receiver.

When reaching the UploadFile-function, I get the following error:

Specified argument was out of the range of valid values. Parameter name: bytesToCopy

Information about the function can be found here. It has the following signature:

public static Microsoft.SharePoint.Client.File UploadFile (this Microsoft.SharePoint.Client.Folder folder, string fileName, System.IO.Stream stream, bool overwriteIfExists);

My code is:

using (System.IO.MemoryStream stream = new System.IO.MemoryStream())
{
    ClientResult<Stream> data = curItem.File.OpenBinaryStream();
    clientContext.ExecuteQuery();

    if (data != null && data.Value != null)
    {

         data.Value.CopyTo(stream);
         UploadedFile = destinationList.RootFolder.UploadFile(curItem.File.Name.ToString(), stream, true);
    }
}

As a note: curItem, destinationList and curItem.File are all loaded in the context.

Edit, complete error:

How to get rid of the error?

Answer 1

A quick google search lead me to this article

Someone had a similar problem (although he figured it had to do with file size) and solved it by resetting the stream before sending it to SharePoint:

using (var stream = content)
{
    ...
    stream.Seek(0, SeekOrigin.Begin); // <-- The missing statement
    ...
}

Hope that works for you as well :)
