Using ValidationEventHandler

using System;
using System.IO;
using System.Xml.Schema;
public class ValidateSchema {
  public static void Main(string [] args) {
    ValidationEventHandler handler = new ValidationEventHandler(ValidateSchema.Handler);
    XmlSchema schema = XmlSchema.Read(File.OpenRead(args[0]),handler);
    schema.rupile(handler);
  }
  public static void Handler(object sender, ValidationEventArgs e) {
    Console.WriteLine(e.Message);
  }
}

Validate Xml

using System;
using System.Xml;
using System.Xml.Schema;
public class MainClass
{
  [STAThread]
  private static void Main()
  {
      string xmlFilename = "test.xml";
      string schemaFilename = "schema.xml";
        
        XmlReaderSettings settings = new XmlReaderSettings();
        settings.ValidationType = ValidationType.Schema;
        XmlSchemaSet schemas = new XmlSchemaSet();
        settings.Schemas = schemas;
        schemas.Add(null, schemaFilename);
        
        settings.ValidationEventHandler += ValidationEventHandler;
        
    XmlReader validator = XmlReader.Create(xmlFilename, settings);                
    
    try
    {
      while (validator.Read()){}
    } catch (XmlException err) {
      Console.WriteLine(err.Message);
    } finally {
      validator.Close();
    }
  }
  private static void ValidationEventHandler(object sender, ValidationEventArgs args)
  {
    Console.WriteLine("Validation error: " + args.Message);
  }
