Before starting the coding, let us have a look at the storage location of documents whenever we add those in to any document libraries, also the location of content type’s document template.
Whenever you open your SharePoint document library using the Actions à Open with windows Explorer, it will show you the physical location of the files already there for your document library.
In this post I am taking the default document library which is “Shared Documents”. If you open this document library in the windows explorer then you can see a template.doc file just beneath the form folder. So now it is pretty easy, isn’t it? Only you need to just find out this file and it's location and create & add the file to your library based upon this base template.
static void Main(string args)
SPSite oSite = new SPSite("http://blr2r08-9:2100/sites/LastTest");
SPWeb oWeb = oSite.OpenWeb();
SPList projectDocumentLibrary = oWeb.Lists["Shared Documents"];
// Retrieves the content type collection from "Shared Documents"
SPContentTypeCollection oContentTypes= projectDocumentLibrary.ContentTypes;
//loop through each content type and create a file based on that content type
foreach (SPContentType oContentType in oContentTypes)
if (oContentType.DocumentTemplateUrl != string.Empty)
// this line does the addition of files . DocumentTemplateUrl will give the template.doc's location which is /LastTest/Shared%20Documents/Forms/template.doc
SPFile oFile = projectDocumentLibrary.RootFolder.Files.Add("TestDoc1.doc", oWeb.GetFile(oContentType .DocumentTemplateUrl).OpenBinary(), true);
SPListItem oItem = oFile.Item;
//just updating the title
oItem["Title"] = "Test";
Once you execute the above code after making appropriate changes as per your SharePoint site, then you can see that it is adding a TestDoc1.doc file in to the Shared Documents library.
