How do you programmatically upload a file to a document library in sharepoint? I am currently making a Windows application using C# that will add documents to a document library list.

Upload using Object Model:
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 myLibrary.Update(); >> Chadworthington, SPSite is part of Microsoft.SharePoint namespace, so you need to add reference to Microsoft.SharePoint.dll. Assuming you are developing on the Server, the dll can be found here: C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\ISAPI\Microsoft.SharePoint.dll
Commented Jun 4, 2009 at 9:23Wait a sec. this code will only work in a box joined to the farm, correct? In any other box, it needs to use msdn.microsoft.com/en-us/library/ee857094.aspx
Commented May 5, 2011 at 2:35 You dont need to call myLibrary.Update(); file adds after Files.Add(..) Commented Jun 10, 2012 at 12:45This worked well for me, except that I had to use a "using" on the filestream when deleting the file afterwards (for the delete to work). I changed it to: using (FileStream fileStream = File.OpenRead(fileToUpload)) < // Upload document SPFile spfile = doclib.Files.Add(fileName, fileStream, replaceExistingFiles); >
Commented Jul 28, 2015 at 22:49This is not a good solution. It needs to be run as someone who is both a DBO and a SP Farm administrator, which is a ridiculous over-priv for the task of uploading a file.
Commented Jun 24, 2016 at 15:52if you get this error "Value does not fall within the expected range" in this line:
SPFolder myLibrary = oWeb.Folders[documentLibraryName]; use instead this to fix the error:
SPFolder myLibrary = oWeb.GetList(URL OR NAME).RootFolder; Use always URl to get Lists or others because they are unique, names are not the best way ;)

Commented Jul 9, 2015 at 12:58 Which row gives you this exception? Commented Jul 12, 2015 at 8:27 What is name of library? is it available at nuget?

Consider to not updating the myLibrary. It can cause concurrency conflicts.
Commented Nov 13, 2013 at 9:07As an alternative to the webservices, you can use the put document call from the FrontPage RPC API. This has the additional benefit of enabling you to provide meta-data (columns) in the same request as the file data. The obvious drawback is that the protocol is a bit more obscure (compared to the very well documented webservices).
For a reference application that explains the use of Frontpage RPC, see the SharePad project on CodePlex.
