如何使用c#编辑内联图像的mapi属性content disposition？

using System;
using Microsoft.Office.Interop.Outlook;

namespace OutlookAttachment
{
    class Program
    {
        static void Main(string[] args)
        {
            // 创建Outlook应用程序对象
            Application outlookApp = new Application();
            
            // 创建邮件消息
            MailItem mailItem = (MailItem)outlookApp.CreateItem(OlItemType.olMailItem);
            
            // 附件集合
            Attachments attachments = mailItem.Attachments;

            // 遍历附件集合，定位到需要编辑MAPI属性的图像附件
            foreach (Attachment attachment in attachments)
            {
                if (attachment.Type == OlAttachmentType.olByValue && attachment.FileName.EndsWith(".jpg"))
                {
                    // 获取图像附件的Content-Disposition属性
                    PropertyAccessor propertyAccessor = attachment.PropertyAccessor;
                    string contentDisposition = (string)propertyAccessor.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x3712001E");

                    // 编辑Content-Disposition属性为"inline"
                    contentDisposition = "inline";

                    // 更新图像附件的Content-Disposition属性
                    propertyAccessor.SetProperty("http://schemas.microsoft.com/mapi/proptag/0x3712001E", contentDisposition);

                    // 打印修改后的Content-Disposition属性值
                    Console.WriteLine("Modified Content-Disposition: " + contentDisposition);

                    // 保存或发送邮件消息
                    mailItem.Save();
                    //mailItem.Send();

                    break;
                }
            }

            // 释放资源
            mailItem = null;
            attachments = null;
            outlookApp = null;
        }
    }
}
