如何在C#中读写XMP元数据？

using System;
using Adobe.XMP;
using Adobe.XMP.Files;

class Program
{
    static void Main(string[] args)
    {
        try
        {
            // 读取XMP元数据
            XmpFile xmpFile = new XmpFile("path/to/file.jpg");
            XmpMeta xmpMeta = xmpFile.GetXmpMeta();
            string creator = xmpMeta.GetPropertyString(XmpConst.NS_DC, "creator");

            Console.WriteLine("Creator: " + creator);

            // 写入XMP元数据
            xmpMeta.SetProperty(XmpConst.NS_DC, "creator", "John Doe");
            xmpFile.SetXmpMeta(xmpMeta);
            xmpFile.Save();

            Console.WriteLine("XMP metadata updated successfully.");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error: " + ex.Message);
        }
    }
}
