C# 使用和处理带有MailMessage的附件
我有以下代码:C# 使用和处理带有MailMessage的附件,c#,email,smtp,attachment,C#,Email,Smtp,Attachment,我有以下代码: using (var msg = new System.Net.Mail.MailMessage()) { msg.Subject = subject; msg.From = new System.Net.Mail.MailAddress(fromEmail); msg.To = new System.Net.Mail.MailAddress(toEmail); msg.Body = body; var attachmen
using (var msg = new System.Net.Mail.MailMessage())
{
msg.Subject = subject;
msg.From = new System.Net.Mail.MailAddress(fromEmail);
msg.To = new System.Net.Mail.MailAddress(toEmail);
msg.Body = body;
var attachment = new System.Net.Mail.Attachment(file);
msg.Attachments.Add(attachment);
//using (var attachment = new System.Net.Mail.Attachment(file))
// msg.Attachments.Add(attachment);
using (var smtp = new System.Net.Mail.SmtpClient("smtp", 587))
{
smtp.Send(msg);
};
}
在我的情况下,文件附件是可选的。当我在
附件上使用时,smtp.Send()
抛出:
内部异常1:ObjectDisposedException:无法访问已关闭的
文件
我的问题是如何正确处理这个问题?
如果我没有在附件上明确使用dispose
,MailMessage
是否也会处理内部附件?请查看.net源代码以获取详细信息
如果有附件,将对其进行处理
protected virtual void Dispose(bool disposing)
{
if (disposing && !disposed)
{
disposed = true;
if(views != null){
views.Dispose();
}
if(attachments != null){
attachments.Dispose();
}
if(bodyView != null){
bodyView.Dispose();
}
}
}
