Help me convert C# 1.1 Xml validation code to C# 2.0 please.
- by Hamish Grubijan
It would be fantastic if you could help me rid of these warnings below.
I have not been able to find a good document. Since the warnings are concentrated in just the private void ValidateConfiguration( XmlNode section ) section, hopefully this is not terribly hard to answer, if you have encountered this before.
Thanks!
'System.Configuration.ConfigurationException.ConfigurationException(string)' is obsolete: 'This class is obsolete, to create a new exception create a System.Configuration!System.Configuration.ConfigurationErrorsException'
'System.Xml.XmlValidatingReader' is obsolete: 'Use XmlReader created by XmlReader.Create() method using appropriate XmlReaderSettings instead. http://go.microsoft.com/fwlink/?linkid=14202'
private void ValidateConfiguration( XmlNode section )
{
// throw if there is no configuration node.
if( null == section )
{
throw new ConfigurationException("The configuration section passed within the ... class was null ... there must be a configuration file defined.", section );
}
//Validate the document using a schema
XmlValidatingReader vreader = new XmlValidatingReader( new XmlTextReader( new StringReader( section.OuterXml ) ) );
// open stream on Resources; the XSD is set as an "embedded resource" so Resource can open a stream on it
using (Stream xsdFile = XYZ.GetStream("ABC.xsd"))
using (StreamReader sr = new StreamReader(xsdFile))
{
vreader.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);
vreader.Schemas.Add(XmlSchema.Read(new XmlTextReader(sr), null));
vreader.ValidationType = ValidationType.Schema;
// Validate the document
while (vreader.Read()) { }
if (!_isValidDocument)
{
_schemaErrors = _sb.ToString();
throw new ConfigurationException("XML Document not valid");
}
}
}
// Does not cause warnings.
private void ValidationCallBack( object sender, ValidationEventArgs args )
{
// check what KIND of problem the schema validation reader has;
// on FX 1.0, it gives a warning for "<xs:any...skip" sections. Don't worry about those, only set validation false
// for real errors
if( args.Severity == XmlSeverityType.Error )
{
_isValidDocument = false;
_sb.Append( args.Message + Environment.NewLine );
}
}
