在C#中以编程方式检查XML文件格式良好的最快方法是什么？

using System;
using System.IO;
using System.Xml;

public class XmlValidation
{
    public static void Main(string[] args)
    {
        string xmlFilePath = "path/to/your/xml/file.xml";
        bool isValid = ValidateXml(xmlFilePath);

        if (isValid)
        {
            Console.WriteLine("XML文件格式良好。");
        }
        else
        {
            Console.WriteLine("XML文件格式不正确。");
        }
    }

    public static bool ValidateXml(string xmlFilePath)
    {
        using (FileStream fs = new FileStream(xmlFilePath, FileMode.Open))
        {
            XmlReaderSettings settings = new XmlReaderSettings();
            settings.ValidationType = ValidationType.DTD;
            settings.ValidationEventHandler += new ValidationEventHandler(ValidationEventHandler);

            XmlReader reader = XmlReader.Create(fs, settings);

            while (reader.Read()) { }

            return true;
        }
    }

    static void ValidationEventHandler(object sender, ValidationEventArgs e)
    {
        throw new ApplicationException("XML文件格式不正确。");
    }
}
