Hola
Lego , cierra tu StreamReader :
Código C:
Ver originalStreamReader fStream = new StreamReader(AppDomain.CurrentDomain.RelativeSearc hPath.ToString() + "\\" + fileName);
String destUrl = SPContext.Current.Site.RootWeb.Url + "/biblioAuditoria/" + fileName;
SPFile item = SPContext.Current.Site.RootWeb.Files.Add(destUrl, fStream.BaseStream));
fStream.Close();
System.IO.File.Delete(AppDomain.CurrentDomain.Rela tiveSearchPath.ToString() + "\\" + fileName);
Nos cuentas. Saludos!
