Examples

The following example creates two documents, one with utf-8 encoding, and one with utf-16 encoding. It then loads the documents and prints the encoding to the console.

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)

This example produces the following output:

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

Remarks

Any value returned by WebName is a valid value.

If you read an encoded document, then this property will be set to the code page name.

If you set this property to a valid code page name, then when serializing, LINQ to XML will serialize with the specified encoding.
