Recently I was at a company who needed a system that deployed documents into their farm programmatically (Lotus to SharePoint conversion) against some business rules. In one of my teaches, the students and I prototyped this example of how to programmatically upload a document into a document library. The code also demonstrates modifying arbitrary meta data that is associated with that document. This concept is nothing that hasn't already been documented in the SDK, but it was a fun example to work through with my students so I figured I'd post our code. See below:
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using Microsoft.SharePoint;
namespace TestUploadFile
{
class Program
{
static void Main(string[] args)
{
// Read a document off the c drive and open a stream
FileStream stream = File.OpenRead(@"c:\test.doc");
byte[] content = new byte[stream.Length];
// Read the file from the stream into the byte array
stream.Read(content, 0, (int)stream.Length);
stream.Close();
// Give the file a name, used as the name of the list
// item once it gets into the document library
string fileNameOnceInLibrary = "justUploaded.doc";
SPSite mySiteCollection = new SPSite("http://intranet");
SPWeb myWeb = mySiteCollection.RootWeb;
// Get the folder that should store the document
// In this case, there's a document library called "Docs"
// within the Root Web of the Site Collection
SPFolder parent = myWeb.Folders["Docs"];
// Within the "Docs" library, add the document into
// a folder called "Folder1"
SPFolder child = parent.SubFolders["Folder1"];
// Add the file to the Files collection and commit to database
SPFile file = child.Files.Add(child.Url + "/" +
fileNameOnceInLibrary, content, true);
child.Update();
// This next portion demonstrates modifying meta data
// on the document that was just uploaded
SPDocumentLibrary docs = (SPDocumentLibrary)myWeb.Lists
[child.ContainingDocumentLibrary];
SPListItem item = docs.Items[file.UniqueId];
item["Department"] = "Marketing";
item.Update();
}
}
}
