如何从内存中制作outlook邮件附件？

using Outlook = Microsoft.Office.Interop.Outlook;

public void CreateOutlookEmailWithAttachment(byte[] attachmentData, string attachmentFileName)
{
    // 创建Outlook应用程序对象
    Outlook.Application outlookApp = new Outlook.Application();

    // 创建邮件对象
    Outlook.MailItem mailItem = (Outlook.MailItem)outlookApp.CreateItem(Outlook.OlItemType.olMailItem);

    // 添加附件
    string tempFilePath = Path.GetTempFileName();
    File.WriteAllBytes(tempFilePath, attachmentData);
    mailItem.Attachments.Add(tempFilePath, Outlook.OlAttachmentType.olByValue, 1, attachmentFileName);

    // 设置邮件属性
    mailItem.Subject = "这是一封带附件的Outlook邮件";
    mailItem.Body = "这是邮件的正文内容";
    mailItem.To = "收件人邮箱地址";

    // 发送邮件
    mailItem.Send();

    // 删除临时文件
    File.Delete(tempFilePath);
}
