有没有办法让XDocument在使用ToString方法时打印xml版本？输出这样的东西:

<?xml version="1.0"?>
<!DOCTYPE ELMResponse [
]>
<Response>
<Error> ...

我有以下内容:

var xdoc = new XDocument(new XDocumentType("Response", null, null, "\n"), ...

这将打印出这个很好的,但它缺少如上所述的"<？xml版本".

<!DOCTYPE ELMResponse [
]>
<Response>
<Error> ...

我知道你可以通过手动输出我自己来做到这一点.只是想知道是否可以使用XDocument.

以下代码生成此输出:

<?xml version="1.0" encoding="utf-16" standalone="yes"?>
<customers>
  <customer>
    <firstName>Jim</firstName>
    <lastName>Smith</lastName>
  </customer>
</customers>

我怎样才能让它encoding="utf-8"代替encoding="utf-16"？

                new Customer {FirstName="Jim", LastName="Smith", Age=27},
                new Customer {FirstName="Hank", LastName="Moore", Age=28},
                new Customer {FirstName="Jay", LastName="Smythe", Age=44},
                new Customer {FirstName="Angie", LastName="Thompson", Age=25},
                new Customer {FirstName="Sarah", LastName="Conners", Age=66}
            };

            Console.WriteLine(BuildXmlWithLINQ(customers));

            Console.ReadLine();

        }
        private static string BuildXmlWithLINQ(List<Customer> customers)
