body: <p>I got this error while creating a document library in sharepoint.</p>
  
  <p><strong>A list, survey, discussion board, or document library with the specified title already exists in this Web site. Please choose another title.</strong></p>
  
  <p>Here is my coding.</p>
  
  <pre><code>                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;
  </code></pre>
