Other answers are correct to suggest Sort  but they seem to have missed the fact that the storage location is typed as IList lt string   Sort is not part of the interface   If you know that ListaServizi will always contain a List lt string gt   you can either change its declared type  or use a cast   If you re not sure  you can test the type   if  typeof List lt string gt   IsAssignableFrom ListaServizi GetType           List lt string gt  ListaServizi  Sort    else             some other solution  there are a few to choose from      Perhaps more idiomatic   List lt string gt  typeCheck   ListaServizi as List lt string gt   if  typeCheck    null      typeCheck Sort    else             some other solution  there are a few to choose from      If you know that ListaServizi will sometimes hold a different implementation of IList lt string gt   leave a comment  and I ll add a suggestion or two for sorting it
