如何使用C#在不知道文件路径的情况下在Outlook中查找实现文件夹

using Outlook = Microsoft.Office.Interop.Outlook;

Outlook.Application outlookApp = new Outlook.Application();
Outlook.NameSpace outlookNamespace = outlookApp.GetNamespace("MAPI");

Outlook.MAPIFolder rootFolder = outlookNamespace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);

private Outlook.MAPIFolder FindFolder(Outlook.MAPIFolder parentFolder, string folderName)
{
    foreach (Outlook.MAPIFolder folder in parentFolder.Folders)
    {
        if (folder.Name == folderName)
        {
            return folder;
        }
        else
        {
            Outlook.MAPIFolder subFolder = FindFolder(folder, folderName);
            if (subFolder != null)
            {
                return subFolder;
            }
        }
    }
    return null;
}

string targetFolderName = "目标文件夹名称";
Outlook.MAPIFolder targetFolder = FindFolder(rootFolder, targetFolderName);

// 查找邮件示例
Outlook.Items items = targetFolder.Items;
foreach (Outlook.MailItem mailItem in items)
{
    // 处理邮件
}

// 保存附件示例
foreach (Outlook.MailItem mailItem in items)
{
    foreach (Outlook.Attachment attachment in mailItem.Attachments)
    {
        attachment.SaveAsFile("保存路径");
    }
}
