一个包含此文档的代码页名称的 String。
示例
下面的示例创建两个文档，一个文档使用 utf-8 编码，另一个使用 utf-16 编码。 然后，该示例加载这两个文档并将编码输出到控制台。
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)
该示例产生下面的输出：
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
