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.

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();     } }
