C# Validate XML against XSD [duplicate]

Answer 1

See this question:

Xml validation using XSD schema

It shows that all you need to do is set the right option when creating your XmlReader:

XmlReaderSettings settings = new XmlReaderSettings();
settings.Schemas.Add(null, xsdFilePath);
settings.ValidationType = ValidationType.Schema;
settings.ValidationEventHandler += new System.Xml.Schema.ValidationEventHandler(settings_ValidationEventHandler);

var reader = XmlReader.Create(source, settings);

You will now get information on validation errors in settings_ValidationEventHandler and the document load will be aborted if required.
