问题描述
将Excel文件作为附件发送时，出现以下错误.
System.Net.Mail.SmtpException:发送文件失败---> System.ObjectDisposedException:无法访问关闭的文件.
在System.Net.Mime.MimeBasePart.EndSend(IAsyncResult asyncResult)
在System.Net.Mail.Message.EndSend(IAsyncResult asyncResult)
在System.Net.Mail.SmtpClient.SendMessageCallback(IAsyncResult asyncResult)
并且文件未发送.
此错误是什么意思?

When sending a excel file as an attachment, I receive the following error.
System.Net.Mail.SmtpException: Failure sending file ---> System.ObjectDisposedException: Cannot access a closed file.
at System.Net.Mime.MimeBasePart.EndSend(IAsyncResult asyncResult)
at System.Net.Mail.Message.EndSend(IAsyncResult asyncResult)
at System.Net.Mail.SmtpClient.SendMessageCallback(IAsyncResult asyncResult)
And the file is not sent.
What does this error mean?
