I need to upload files with specific information(custom fields) into sharepoint document library via custom windows application.

I have no idea how to do it, anyone has any examples how to do it either via web service or other methods?


Problem #2: During design time, i can add MS.sharepoint.dll without a problem, however when during compilation, it shows:

The type or namespace name 'SPWeb' could not be found (are you missing a using directive or an assembly reference?)

I'm pretty sure I added the dll and there's no error, only after compile it shows error.

  • There are various solutions to do so 1) Server Object Model 2) Client Object Model are you going to run this Windows Application in a Client Machine where SharePoint is not installed?

Check this link, http://www.ktskumar.com/blog/2009/03/upload-document-from-local-machine-to-sharepoint-library/

This blog post explains how to upload the document to SharePoint using WebService

  • how do i know i have this or not ? copyService.Url = webUrl+”/_vti_bin/copy.asmx”;

  • To check the URL, you have to browse through, http://<SiteUrl>/_vti_bin/copy.asmx . copyservice refers the WebService Reference. webUrl refers the website url Sep 11, 2012 at 5:53
  • a) Link to your own blog but say it's your own blog. b) Please post the gist of your post and not just the link, some day this link might be broken.

You can use an HTTP PUT request to put document in the library. The code may be (adapt regarding your needs) :

Uri destUri = new Uri("http://server/sites/mysite/myweb/mylibrary/document.doc");
using(FileStream inStream = File.OpenRead(@"c:\doc\document.doc"))
    WebRequest req = WebRequest.Create(destUri);
    req.Method = "PUT";
    req.Credentials = CredentialCache.DefaultCredentials; // assuming windows Auth
    using(Stream outStream = req.GetRequestStream())
        CopyStream(inStream, outStream);

The main advantage of this method is that you don't have any sharepoint code. This is standard http webdav behavior.

The major drawback is that you don't have set any metadata.

To fix the later issue, you can use the standard web services of SharePoint.

  • in that case, i will have to use standard web services of SP .. do i need to install anything on client ?

  • No. Simply add a service reference to the SharePoint web services in your VS project (lists.asmx or ListData.svc)

  • Eventhough there is no way of setting the metadata, I like this solution best because it also enables uploading files to Documentsets and SharePoint Folders. Jan 22, 2015 at 8:19

you can also use a Client Object Model Solution as Below

using (ClientContext clientContext = new ClientContext("http://contoso.com/subsite"))
        List documentLibrary = clientContext.Web.Lists.GetByTitle("List Title");
        FileCreationInformation newFile = new FileCreationInformation();
        newFile.Content = "Add File Stream Array";
        newFile.Overwrite = true;
        newFile.Url = "http://contoso.com/subsite/listurl/" + strFileName.Trim();
        Microsoft.SharePoint.Client.File uploadFile = documentLibrary.RootFolder.Files.Add(newFile);
    uploadFile.ListItemAllFields["Column Internal Name"] = "Column Internal Value";

    catch (Exception ex)
        throw ex;

And regarding your Problem No 2: Please make sure that you have opened up the Visual Studio 2010 as Administrator. Also change your project settings such that it is compiled with .Net Framework 3.5 not with Framework 4.0


I would use Object model as shown in the following code sample:

String fileToUpload = @"C:\YourFile.txt";
String sharePointSite = "http://yoursite.com/sites/Research/";
String documentLibraryName = "Shared Documents";

using (SPSite oSite = new SPSite(sharePointSite))
    using (SPWeb oWeb = oSite.OpenWeb())
        if (!System.IO.File.Exists(fileToUpload))
            throw new FileNotFoundException("File not found.", fileToUpload);                    

        SPFolder myLibrary = oWeb.Folders[documentLibraryName];

        // Prepare to upload
        Boolean replaceExistingFiles = true;
        String fileName = System.IO.Path.GetFileName(fileToUpload);
        FileStream fileStream = File.OpenRead(fileToUpload);

        // Upload document
        SPFile spfile = myLibrary.Files.Add(fileName, fileStream, replaceExistingFiles);

        // Commit
