How can I resolve the schemaLocation attribute of an .XSD when all of my .XSD's are stored as resources?

Question

I am working on a project where I need to generate XML files based on nested XSD\'s. e.g. ORDER has a reference to PERSON, PERSON has a reference to ADDRESS, etc.

To get rid of the error, change type="Addresses" to name="Addresses" in your PERSON.xsd file.

It is better to go with the code below to get schemas compiled. The important things are to make sure you establish a base uri (since you're reading from a stream), to use an XmlSchemaSet instead, and a custom resolver (to read files as embedded resources).

using System;
using System.IO;
using System.Text;
using System.Xml;
using System.Xml.Schema;

namespace ConsoleApplication3
{
    class Program
    {
        class XmlResolver : XmlUrlResolver
        {
            internal const string BaseUri = "schema://";

            public override object GetEntity(Uri absoluteUri, string role, Type ofObjectToReturn)
            {
                if (absoluteUri.Scheme == "schema")
                {
                    switch (absoluteUri.LocalPath)
                    {
                        case "/ADDRESS.xsd":
                            return new MemoryStream(Encoding.UTF8.GetBytes(Resource.ADDRESS));
                        case "/PERSON.xsd":
                            return new MemoryStream(Encoding.UTF8.GetBytes(Resource.PERSON));
                    }
                }
                return base.GetEntity(absoluteUri, role, ofObjectToReturn);
            }
        }

        static void Main(string[] args)
        {
            using (XmlReader reader = XmlReader.Create(new StringReader(Resource.PERSON), new XmlReaderSettings(), XmlResolver.BaseUri))
            {
                XmlSchemaSet xset = RetrieveSchemaSet(reader);
                Console.WriteLine(xset.IsCompiled);
            }
        }

        private static XmlSchemaSet RetrieveSchemaSet(XmlReader reader)
        {
            XmlSchemaSet xset = new XmlSchemaSet() { XmlResolver = new XmlResolver() };
            xset.Add(XmlSchema.Read(reader, null));
            xset.Compile();
            return xset;
        }
    }
}
