Hi Sridhara,

Really excellent article. It helped me a lot.

I am using the second method(i.e. using FileStream object) to upload files. I am using multiple threads to upload files to same or different libraries in sharepoint 2010 from my win application. I am getting following errors sometimes:

1. Cannot invoke HTTP DAV request. There is a pending query.

2. The remote server returned an error: (409) Conflict.

Can you please let me know the root cause for these and any workaround possible for these issues?

Thanks in advance.

Hi Sridhara

Thanks for this article. It help me alot

@am20an if you still face the problem or anybody else is having

then here is the solution which work for me

ClientContext ctx = new ClientContext("http://yoursharepointURL");

               Web currentWeb = ctx.Web;

               ctx.Load(currentWeb);

               ctx.ExecuteQuery();

               using (FileStream fs = new FileStream(@"C:\data\TestFile.pptx", FileMode.Open))

{ Microsoft.SharePoint.Client.File.SaveBinaryDirect(ctx, "/Sample Documents/TestFile from client.pptx", fs, true);

               }

               Console.WriteLine("Uploaded File Successfully");

and be sure the "http://yoursharepointURL/Sample Documents" is a valid path where you want to upload the file.

Hope this work for you too.

Thanks & Regards

Hi Sridhara,

thanks for example code!

It works fine on the server-machine, but using a other system in the network the method "SaveBinaryDirect" throw an exception ("The underlying connection was closed: A connection that was expected to maintain their closed down the server").

My activedirectory user has full permission for the site.

I think it isn't a permission problem, because all other functions for example read items or updating items works fine.

Only the method SaveBinaryDirect() throw an exception.

Do you know this error? I hope you can help me.

Best regards!

Sven

Hey is there anyway to attach meta data to the document during upload )with either method)?  or do you have to come back and do it after?

Hi, I too am having problems uploading files using SaveBinaryDirect. I keep getting an error HTTP DAV, the same as am20an. Have you a solution for this?

Kind regards

@Blaithin please forgive the asking of potentially stupid questions, I'm just trying to narrow down the problem scope and make sure there's actually a bug:

Can you connect Windows on the machine you're using directly to the SP site's WebDAV? google.com/search

Is the URL you've passed as a parameter to the client context constructor the same URL you'd use to connect to the WebDAV through Windows on that client machine?

Hi All,

I am getting the error -The remote server returned an error: (404) Not Found.

While adding the attachment to the list Item using

Microsoft.SharePoint.Client.File.SaveBinaryDirect(clientContext, attachmentPath, stream, true);

In my case i have created an event receiver feature already running on this list, which will add an  attachment to the list item and will delete the same when the item is added.

I hope this will create the attachment folder for this list item, but still while adding attachments i'am getting the above file not found exception.

Please anybody guide me on this .

Thanks in Advance,

Dhileep.

Plz post code for list item with attachment. here only document library

If I use Microsoft.SharePoint.Client.File.SaveBinaryDirect I get error:

Is this because of some protocols are unavailable in our company's intranet?

I found the first method did not work for me until I added a

context.Load(docs);

between lines 10 and 11.
