Programmatically Add a File in SharePoint

Yet another MSDN code sample 🙂 This one is for how to programmaitcally copy and/or add a file to a SharePoint library. Everything is commented in line.

//open target site collection
using(SPSite site = new SPSite(“vendorurl”))
//open target web
using(SPWeb vendorWeb = site.OpenWeb(“VendorWeb -RelativeURL”))
vendorWeb.AllowUnsafeUpdates = true;
//get folder of root of the target document library
SPFolder targetFolder = web.Lists(“targetLibraryName”).Folder();
//get the file collection to add our file in to
SPFileCollection _files = targetFolder.Files;
//get the byte array of the source item to send to the library
byte[] fileToCopy = sourceItem.File.OpenBinary();
//construct the proper url – usually this is handed off to a function that returns a string
string listurl = targetList.DefaultViewUrl;
if (listurl.Contains(“/Forms/”) == true)
int index = listurl.IndexOf(“/Forms/”);
listurl = listurl.Remove(index);
else if (listurl.Contains(“.aspx”) == true)
int index = listurl.LastIndexOf(“/”);
listurl = listurl.Remove(index);
//add our file to sharepoint, the sourceItem.Properties copies metadata when copying from an existing sharepoint file, the true at the end is for overwriting the existing copy of the file if any
SPFile file = _files.Add(listurl + “/” + item.File.Name.ToString(), fileToCopy, sourceItem.Properties, true);
//get the splistitem of the uploaded file
SPListItem finalItem = file.Item;
//update a field in the uploaded file
finalItem[“originatingDocumentId”] = sourceItem[“DocumentID”].ToString();
//update the list item
//finish up 🙂
vendorWeb.AllowUnsafeUpdates = false;

        I was just talking with some of your people at Slalom consulting while I was Dallas SharePointFest. You going to be at Denver or Chicago SharePointFest?

          I’m out of the San Francisco office so won’t be going to either unfortunately.

            Marten, have you ever or thought about submitting for your MVP?

          • #6 by Maarten on March 24, 2011 - 11:26 am

            Would love to get MVP. Do they allow self-submit now? I thought you had to be recommended by a Microsoft employee or an existing MVP.

    Yes you can submit yourself. I would get to know the MS People in your area. Take them out to lunch talk about MS. Here is the link to submit yourself.

      Thanks! I went ahead and nominated myself. Let me know if you’d like a nomination or would be willing to nominate me as well.

        Do you have a email address so this does not have to be so open. Or just email me.

        I would be happy to, did you get the format correct?
