Hi,
The code that you have posted is adding data to the list or document library. Do you want to add or fetch data from or to document library?
You can refer following link for Inserting/Updating documents in document library:
http://blogs.perficient.com/microsoft/2009/04/working-with-documents-stored-in-sharepoint-document-library-programmatically/
For fetching data from document library, you can use following code:
using (SPSite site = new SPSite(SPContext.Current.Site.Url))
using (SPWeb web = site.OpenWeb())
string documentLibName = "Doc_Lib_Name";
SPFolder docLibrary = web.GetFolder(documentLibName);
foreach (SPFile file in docLibrary.Files)
var customColValue = file.Item["Custom_Column_Name"];
Hope this helps!
