Problem creating XmlWriter as UTF8?

Question

Hi,

I'm having trouble creating an xml document with UTF8 encoding. See this example:

var settings = new XmlWriterSettings { Indent = true, Encoding = Encoding.UTF8 };
var xml = new StringBuilder();
using (var writer = XmlWriter.Create(xml, settings))
{
    // Here writer.Settings.Encoding == UTF16. Why???
}

As the example shows - I'm getting UTF16 regardless of the settings. Why? And how can I create an UTF8 Xml Writer?

Answer 1

Strings in .NET are always Unicode, that is, UTF-16. There is no way to write any other encoding to a string.

If you write to a file, or to a stream, then you can get whatever encoding you like.

I dont understand your answer here - the problem is the XmlWriter settings. Why does it have a "Encoding" setter if I can't set it? It must be possible somehow to have the XmlWriter.Settings.Encoding == UTF8?

You can set it, except when it isn't overridden by something else. If you're writing to a string, then the encoding will be overridden by UTF-16.

If you write to, for instance, a MemoryStream, then your encoding will take effect.

Ok I get that now - it depends on the target. I have tried to write a file and the encoding is changed to utf8. Thanks!
