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.
This question is related to
c#
sharepoint
upload
You can upload documents to SharePoint libraries using the Object Model or SharePoint Webservices.
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();
}
}
As 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.
if 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 ;)
I used this article to allow to c# to access to a sharepoint site.
http://www.thesharepointguide.com/access-office-365-using-a-console-application/
Basically you create a ClientId and ClientSecret keys to access to the site with c#
Hope this can help you!
With SharePoint 2013 new library, I managed to do something like this:
private void UploadToSharePoint(string p, out string newUrl) //p is path to file to load
{
string siteUrl = "https://myCompany.sharepoint.com/site/";
//Insert Credentials
ClientContext context = new ClientContext(siteUrl);
SecureString passWord = new SecureString();
foreach (var c in "mypassword") passWord.AppendChar(c);
context.Credentials = new SharePointOnlineCredentials("myUserName", passWord);
Web site = context.Web;
//Get the required RootFolder
string barRootFolderRelativeUrl = "Shared Documents/foo/bar";
Folder barFolder = site.GetFolderByServerRelativeUrl(barRootFolderRelativeUrl);
//Create new subFolder to load files into
string newFolderName = baseName + DateTime.Now.ToString("yyyyMMddHHmm");
barFolder.Folders.Add(newFolderName);
barFolder.Update();
//Add file to new Folder
Folder currentRunFolder = site.GetFolderByServerRelativeUrl(barRootFolderRelativeUrl + "/" + newFolderName);
FileCreationInformation newFile = new FileCreationInformation { Content = System.IO.File.ReadAllBytes(@p), Url = Path.GetFileName(@p), Overwrite = true };
currentRunFolder.Files.Add(newFile);
currentRunFolder.Update();
context.ExecuteQuery();
//Return the URL of the new uploaded file
newUrl = siteUrl + barRootFolderRelativeUrl + "/" + newFolderName + "/" + Path.GetFileName(@p);
