how to generate xml schema with UTF-8 instead of UTF-16

[comic_rage]

Hi,

I am writing code with C# to generate xml schema, however, the
following code generate a UTF-16 in the first line. This will create
some problems. How can get the code/missing what part of the code in C#
to generate a first line with UTF-8 instead of UTF-16? Thanks,

public XmlSchema CreateSchemaRoot()
{
schema.ElementFormDefault = XmlSchemaForm.None;
schema.AttributeFormDefault = XmlSchemaForm.Unqualified;
schema.Version = "1.0";
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("xsd", schemaNS);
schema.Namespaces = ns;
return schema;
}

I don't see any statement in that code snippet that serializes the schema.
The following is a complete code snippet creating an example schema and
serializing it using a StreamWriter which by default uses UTF-8 to
encoded data:

XmlSchema exampleSchema = new XmlSchema();

XmlSchemaElement elementGod = new XmlSchemaElement();
elementGod.Name = "God";
elementGod.SchemaTypeName = new XmlQualifiedName("string",
XmlSchema.Namespace);

exampleSchema.Items.Add(elementGod);

exampleSchema.Compile(new ValidationEventHandler(ValidationHandler));

XmlNamespaceManager namespaceManager = new XmlNamespaceManager(new
NameTable());
namespaceManager.AddNamespace("xs", XmlSchema.Namespace);

using (StreamWriter schemaWriter = new
StreamWriter(@"test2005102601Xsd.xml")) {
exampleSchema.Write(schemaWriter, namespaceManager);
}

so that the resulting schema file looks as follows:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="God" type="xs:string" />
</xs:schema>

So whatever you are trying, I don't think there is anything to change in
the code you presented, you simply need to make sure to serialize the
schema in a way such that UTF-8 is used as the encoding. My sample shows
one way with the StreamWriter.
