Here is the XmlResolver deriven class, just for test purpose, it return null

class FileUriResolver : XmlResolver
{
public FileUriResolver() :
 base()
{
}

public override ICredentials Credentials
{
 set
 {
  System.Console.WriteLine("FileUriResolver - set Credentials called");
 }
}

public override object GetEntity(Uri absoluteUri, string role, Type
ofObjectToReturn)
{
 System.Console.WriteLine("absoluteUri=" + absoluteUri.AbsolutePath + ",
role=" + role + ", ofObjectToReturn=" + ofObjectToReturn.ToString());
 return null;
}

public override Uri ResolveUri(Uri baseUri, string relativeUri)
{
 System.Console.WriteLine("baseUri=" + baseUri.AbsolutePath + ",
relativeUri=" + relativeUri);
 return null;
}
}

Here is the code that read and compile the schema

public void Load(string schemaName)
{
Stream s = new FileStream(schemaName, FileMode.Open, FileAccess.Read);

ValidationEventHandler eventHandler = new
ValidationEventHandler(this.ValidationHandler);
XmlSchema schema = XmlSchema.Read(s, eventHandler);

schema.Compile(eventHandler, new FileUriResolver());
}

When I run it, I didn't see any of the Console.WriteLine print out, and I am
getting these events from ValidationHandler:

Warning:Cannot resolve schemaLocation attribute. An error occurred at , (19,
3).
....
Error:Type 'PartnerDescription_type5' is not declared. An error occurred at
, (177, 6).
....

The 'PartnerDescription_type5' is a complex type defined in the one of the
include schema.

thanks,
Benson.
