private void按钮1\u单击（对象发送者，RibbonControlEventArgs e）
{
Outlook.Inspector currInspector=null；
Outlook.MailItem mail=null；
Outlook.Attachments=null；
//工作时更改为生产路径，下面是测试路径
字符串路径=@“H:\Customer Service”；
字符串archivePath=@“H:\Customer Service\Helpers”；
尝试
{
currInspector=Globals.ThisAddIn.Application.ActiveWindow（）；
mail=（Outlook.MailItem）currInspector.CurrentItem；
附件=mail.attachments；
对于（int i=1；i您需要为
SaveAsFile
方法指定完全限定的路径和文件名，而不仅仅是文件夹路径：

string filename = Path.Combine(archivePath , vendFile.FileName);
vendFile.SaveAsFile(filename);
