Contoh

Contoh berikut membuat dua dokumen, satu dengan pengodean utf-8, dan satu dengan pengodean utf-16. Kemudian memuat dokumen dan mencetak pengodean ke konsol.

Console.WriteLine("Creating a document with utf-8 encoding");
XDocument encodedDoc8 = new XDocument(
    new XDeclaration("1.0", "utf-8", "yes"),
    new XElement("Root", "Content")
);
encodedDoc8.Save("EncodedUtf8.xml");
Console.WriteLine("Encoding is:{0}", encodedDoc8.Declaration.Encoding);
Console.WriteLine();

Console.WriteLine("Creating a document with utf-16 encoding");
XDocument encodedDoc16 = new XDocument(
    new XDeclaration("1.0", "utf-16", "yes"),
    new XElement("Root", "Content")
);
encodedDoc16.Save("EncodedUtf16.xml");
Console.WriteLine("Encoding is:{0}", encodedDoc16.Declaration.Encoding);
Console.WriteLine();

XDocument newDoc8 = XDocument.Load("EncodedUtf8.xml");
Console.WriteLine("Encoded document:");
Console.WriteLine(File.ReadAllText("EncodedUtf8.xml"));
Console.WriteLine();
Console.WriteLine("Encoding of loaded document is:{0}", newDoc8.Declaration.Encoding);
Console.WriteLine();

XDocument newDoc16 = XDocument.Load("EncodedUtf16.xml");
Console.WriteLine("Encoded document:");
Console.WriteLine(File.ReadAllText("EncodedUtf16.xml"));
Console.WriteLine();
Console.WriteLine("Encoding of loaded document is:{0}", newDoc16.Declaration.Encoding);

Console.WriteLine("Creating a document with utf-8 encoding")
Dim encodedDoc8 As XDocument = _
        <?xml version="1.0" encoding="utf-8" standalone="yes"?>
            <Root>Content</Root>
encodedDoc8.Save("EncodedUtf8.xml")
Console.WriteLine("Encoding is:{0}", encodedDoc8.Declaration.Encoding)
Console.WriteLine()

Console.WriteLine("Creating a document with utf-16 encoding")
Dim encodedDoc16 As XDocument = _
        <?xml version="1.0" encoding="utf-16" standalone="yes"?>
            <Root>Content</Root>

encodedDoc16.Save("EncodedUtf16.xml")
Console.WriteLine("Encoding is:{0}", encodedDoc16.Declaration.Encoding)
Console.WriteLine()

Dim newDoc8 As XDocument = XDocument.Load("EncodedUtf8.xml")
Console.WriteLine("Encoded document:")
Console.WriteLine(File.ReadAllText("EncodedUtf8.xml"))
Console.WriteLine()
Console.WriteLine("Encoding of loaded document is:{0}", newDoc8.Declaration.Encoding)
Console.WriteLine()

Dim newDoc16 As XDocument = XDocument.Load("EncodedUtf16.xml")
Console.WriteLine("Encoded document:")
Console.WriteLine(File.ReadAllText("EncodedUtf16.xml"))
Console.WriteLine()
Console.WriteLine("Encoding of loaded document is:{0}", newDoc16.Declaration.Encoding)

Contoh ini menghasilkan output berikut:

Creating a document with utf-8 encoding
Encoding is:utf-8

Creating a document with utf-16 encoding
Encoding is:utf-16

Encoded document:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Root>Content</Root>

Encoding of loaded document is:utf-8

Encoded document:
<?xml version="1.0" encoding="utf-16" standalone="yes"?>
<Root>Content</Root>

Encoding of loaded document is:utf-16

Keterangan

Nilai apa pun yang dikembalikan oleh WebName adalah nilai yang valid.

Jika Anda membaca dokumen yang dikodekan, maka properti ini akan diatur ke nama halaman kode.

Jika Anda mengatur properti ini ke nama halaman kode yang valid, maka saat melakukan serialisasi, LINQ ke XML akan diserialisasikan dengan pengodean yang ditentukan.
