您可以用這個驗證sample：

using System; 
using System.Collections; 
using System.Data; 
using System.IO; 
using System.Xml; 
using System.Xml.Schema; 
using System.Text; 

public class XMLValidator 
{ 
    // Validation Error Count 
    static int ErrorsCount = 0; 

    // Validation Error Message 
    static string ErrorMessage = ""; 

    public static void ValidationHandler(object sender, 
             ValidationEventArgs args) 
    { 
     ErrorMessage = ErrorMessage + args.Message + "\r\n"; 
     ErrorsCount ++; 
    } 

    public void Validate(string strXMLDoc) 
    { 
     try 
     { 
      // Declare local objects 
      XmlTextReader   tr = null; 
      XmlSchemaCollection xsc = null; 
      XmlValidatingReader vr = null; 

      // Text reader object 
      tr = new XmlTextReader(urlpath); 
      xsc = new XmlSchemaCollection(); 
      xsc.Add(null, tr); 

      // XML validator object 

      vr = new XmlValidatingReader(strXMLDoc, 
         XmlNodeType.Document, null); 

      vr.Schemas.Add(xsc); 

      // Add validation event handler 

      vr.ValidationType = ValidationType.Schema; 
      vr.ValidationEventHandler += 
        new ValidationEventHandler(ValidationHandler); 

      // Validate XML data 

      while(vr.Read()); 

      vr.Close(); 

      // Raise exception, if XML validation fails 
      if (ErrorsCount > 0) 
      { 
       throw new Exception(ErrorMessage); 
      } 

      // XML Validation succeeded 
      Console.WriteLine("XML validation succeeded.\r\n"); 
     } 
     catch(Exception error) 
     { 
      // XML Validation failed 
      Console.WriteLine("XML validation failed." + "\r\n" + 
      "Error Message: " + error.Message); 
     } 
    } 
} 

這個代碼反序列化：

var reader = new StringReader(xmlString); 
     var serializer = new XmlSerializer(typeof(radio)); 
     var instance = (radio)serializer.Deserialize(reader); 

     return instance;
