How do I dynamically create an XML schema in C#?

I try to dynamically create an XML schema (XSD) from C#, using the conventional XElement and XAttribute classes, but it is not valid to specify any names with colons. That is, I cannot create the element <xs:element> using the code

... = new XElement("xs:element");

because ":" is not allowed.

What is the correct way of dynamically building a schema in C# then?

To create schemas, you should be using the XmlSchema class. The link below provides a comprehensive example of creating one programmatically:

http://msdn.microsoft.com/en-us/library/9ta3w88s.aspx


Example:

static void Main(string[] args)
{
    var schema = new XmlSchema();

    // <xs:element name="myElement" type="xs:string"/>
    var myElement = new XmlSchemaElement();
    schema.Items.Add(myElement);
    elementCat.Name = "myElement";
    elementCat.SchemaTypeName = 
        new XmlQualifiedName("string", "http://www.w3.org/2001/XMLSchema");

    // writing it out to any stream
    var nsmgr = new XmlNamespaceManager(new NameTable());
    nsmgr.AddNamespace("xs", "http://www.w3.org/2001/XMLSchema");
    schema.Write(Console.Out, nsmgr);

    Console.ReadLine();
}

When creating new XML elements, you should be aware that the part before the colon (in this case, xs) is actually an alias for the XML namespace (in the case of an XSD, xs usually refers to http://www.w3.org/2001/XMLSchema). So, to continue using XDocument to build your XSD, you would want to use:

XNamespace ns = new XNamespace("http://www.w3.org/2001/XMLSchema");
... = new XElement(ns + "element");

See the example here: http://msdn.microsoft.com/en-us/library/bb292758.aspx

I wrote a blog about that very subject. You can use a DataTable to save a schema.
