Use an XmlReader with XmlReaderSettings set up for validation:

XmlReaderSettings settings = new XmlReaderSettings();
settings.ValidationType = ValidationType.Schema;
settings.Schemas.Add(null, "schema.xsd");
bool valid = true;
settings.ValidationEventHandler += delegate(object sender,
ValidationEventArgs vargs)
{
if (vargs.Severity == XmlSeverityType.Error)
{
valid = false;
}
Console.WriteLine("{0}: {1}", vargs.Severity, vargs.Message);
};

using (XmlReader reader = XmlReader.Create(@"doc.xml", settings))
{
while (reader.Read()) {}
}
Console.WriteLine("Document is {0}.", valid ? "valid": "not valid");
