I have come across a scenario where I needed to create a document library programmatically inside SharePoint 2010 site collection, The “Document Library” is actually a list in SharePoint 2010 but just the template type is different.

Here is a method which I used to create a custom document library programatically.

protected void CreateNewDocumentLibrary()

{

SPSite site = SPContext.Current.Site;

SPWeb web = site.OpenWeb();

SPListTemplateType tempType = SPListTemplateType.DocumentLibrary;

web.Lists.Add("EbloginDocLibrary", null, tempType);

}

Once you run this code, go to “All site content” of your site collection you will see a new document library as you can see in below pic.
