下面的代碼產生這樣的輸出:如何強制XDocument在聲明行中輸出「UTF-8」?
<?xml version="1.0" encoding="utf-16" standalone="yes"?>
<customers>
<customer>
<firstName>Jim</firstName>
<lastName>Smith</lastName>
</customer>
</customers>
我怎樣才能得到它產生encoding="utf-8"
,而不是encoding="utf-16"
?
using System;
using System.Collections.Generic;
using System.IO;
using System.Xml.Linq;
namespace test_xml2
{
class Program
{
static void Main(string[] args)
{
List<Customer> customers = new List<Customer> {
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)
{
XDocument xdoc =
new XDocument(
new XDeclaration("1.0", "utf-8", "yes"),
new XElement("customers",
new XElement("customer",
new XElement("firstName", "Jim"),
new XElement("lastName", "Smith")
)
)
);
var wr = new StringWriter();
xdoc.Save(wr);
return wr.GetStringBuilder().ToString();
}
}
public class Customer
{
public string FirstName { get; set; }
public string LastName { get; set; }
public int Age { get; set; }
public string Display()
{
return String.Format("{0}, {1} ({2})", LastName, FirstName, Age);
}
}
}
就像API中的一個bug,序列化程序忽略了XDeclaration中的這個值。 – 2013-10-21 15:04:58
@KirkWoll不是真的,因爲XML的默認編碼是UTF8,所以可以省略。因此它引發了爲什麼需要在那裏顯式編寫UTF-8的問題。可能問題是UTF-16存在,而不是UTF-8。 – 2014-06-06 05:49:36
最簡單的解決方案,效果很棒! – BJladu4 2016-02-16 10:23:52
