Error with creating Document Library in SharePoint

Question

I got this error while creating a document library in sharepoint.

A list, survey, discussion board, or document library with the specified title already exists in this Web site. Please choose another title.

Here is my coding.

                SPSite site = new SPSite(url);
                SPWeb oWebsite = site.OpenWeb();
                oWebsite.AllowUnsafeUpdates = true;
                Guid customListID = oWebsite.Lists.Add(docLibraryName, docLibraryName, SPListTemplateType.DocumentLibrary);
                oWebsite.Update();
                oWebsite.AllowUnsafeUpdates = false;

Thanks.

UPDATE:

forget to mention that there is no such document library with the name I am trying to add.

Answer 1

Use SharePoint designer and connect to that site. You may find that a folder with that name has been created which is causing the code to think that the list already exists. Delete that folder and you should be all set.
