你将如何在 C# 中构建这个 xml

我需要生成这个看起来简单的 XML，寻找一种干净的方法来生成它。

<order>
<user>2343></user>
<creditcardtype>2333></creditcarttype>
<country>USA</country>
<orderDetails>
   <amount>23434</amount>
   <shipping>32</shipping>
</orderDetails>
</order>

Since XDocument已被采取，这是一个XmlWriter answer:

    StringWriter sw = new StringWriter();
    using (XmlWriter xw = XmlWriter.Create(sw)) {
        xw.WriteStartElement("order");
        xw.WriteElementString("user", "2343");
        xw.WriteElementString("creditcardtype", "2333");
        xw.WriteElementString("country", "USA");
        xw.WriteStartElement("orderDetails");
        xw.WriteElementString("amount", "23434");
        xw.WriteElementString("shipping", "32");
        xw.WriteEndElement();
        xw.WriteEndElement();
    }
    string s = sw.ToString();

Or with XmlSerializer:

[XmlRoot("order")] public class Order {
    [XmlElement("user")] public int User { get; set; }
    [XmlElement("creditcardtype")] public int CreditCardType { get; set; }
    [XmlElement("country")] public string Country { get; set; }
    [XmlElement("orderDetails")] public OrderDetails Details { get; set; }
}
public class OrderDetails {
    [XmlElement("amount")] public int Amount { get; set; }
    [XmlElement("shipping")] public int Shipping { get; set; }
}
....
var order = new Order {
    User = 2343, CreditCardType = 2333, Country = "USA",
    Details = new OrderDetails {
        Amount = 23434,
        Shipping = 32
    }
};
XmlSerializer ser = new XmlSerializer(order.GetType());
StringWriter sw = new StringWriter();
ser.Serialize(sw, order);
string s = sw.ToString();
