You can upload documents to SharePoint libraries using the Object Model or SharePoint Webservices and this article about how to upload a file and folders recursively from a local folder to a folder on a Microsoft SharePoint Foundation site using the Object Model.
I was assigned a project to Migrate DOORS (Dynamic Object-Oriented Requirements System) data into the TFS 2010 SharePoint portal server. The DXL script is take care of the extraction part and stored the files into the local folders. Then I Googled around to find a way to upload files recursively to SharePoint server, but no use. So I decided to do some research on it and came up with this code.
The Microsoft.SharePoint.dll is used to access the Sharepoint object model.
Code for Uploading File to Document Library
localPath = txtLocalPath.Text; sharePointSite = txtServerURL.Text; documentLibraryName = txtLibrary.Text;
using (SPSite oSite = new SPSite(sharePointSite))
oWeb = oSite.OpenWeb();
catch (Exception ex)
MessageBox.Show("Error:" + ex.Message );
CreateDirectories(string path, SPFolderCollection oFolderCollection)
CreateDirectories method is a recursive method which accepts two parameters. The
path parameter specifies the path of the source location in the file system of the local computer, and the
oFolderCollection parameter specifies the folder collection of the destination.
private void CreateDirectories(string path, SPFolderCollection oFolderCollection)
foreach (FileInfo oFI in new DirectoryInfo(path).GetFiles())
FileStream fileStream = File.OpenRead(oFI.FullName);
SPFile spfile = oFolderCollection.Folder.Files.Add
(oFI.Name, fileStream, true);
foreach (DirectoryInfo oDI in new DirectoryInfo(path).GetDirectories())
string sFolderName = oDI.FullName.Split('\\')
[oDI.FullName.Split('\\').Length - 1];
SPFolder spNewFolder = oFolderCollection.Add(sFolderName);
//Recursive call to create child folder
- The size of the file that is uploaded cannot exceed 2 GB.
- For all this code to execute, current logged in user should have create and upload, delete permissions at respective document library.
