How to: Upload a file/document using the SharePoint Object Model

With this simple article, I'm walking you through the process of uploading any file to your Document Library.

Note; Since this is done through the local API, you need to have this code running on the server. That means that it's ideal to use in for example a FeatureReceiver or EventReceiver. You cannot run this code on the client in e.g. a Windows Form, then you'll need to utilize the SharePoint WebServices instead.

Code to upload a file/document to a SharePoint Document Library

Use the following code to get you started in uploading a file using the object model. It really isn't that hard :-)

// Getting a reference to the document library
var sp = new SPSite("http://localhost");
var site = sp.OpenWeb();
var folder = site.GetFolder("Documents");
var files = folder.Files;

// Opening a filestream
var fStream = File.OpenRead("C:\\MyDocument.docx");
var contents = new byte[fStream.Length];
fStream.Read(contents, 0, (int)fStream.Length);
fStream.Close();

// Adding any metadata needed
var documentMetadata = new Hashtable {{"Comments", "Hello World"}};

// Adding the file to the SPFileCollection
var currentFile =
files.Add("Documents/MyDocument.docx", contents, documentMetadata, true);

site.Dispose();
sp.Dispose();

As you can see in the image below, the metadata "Comments" has been filled in as per the metadata I specified in the code above.

Simple as that. Over and out!
