发送邮件时出现 asp.net NetworkInformationException - 原因是什么？
SmtpClient smtp = new SmtpClient(smtpServer);
smtp.Send(msgMail);
在第二行，有时会抛出此异常：
System.Net.NetworkInformation.NetworkInformationException:
with Message: "A non-blocking socket operation Could not be Completed Again"
这是什么意思？可能是什么原因？
一般情况下，邮件发送在大多数情况下都可以正常工作。 这是一台 IIS7 Windows 2008 Server 计算机。
谢谢。
编辑：
我在这里发现了一些东西： http://www.thevbzone.com/modWINSOCK.bas
Public Const WSAEWOULDBLOCK = (WSABASEERR + 35) ' A non-blocking socket operation could not be completed immediately
MSDN 对此错误进行了说明（< a href="http://msdn.microsoft.com/en-us/library/ms740668%28VS.85%29.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us /library/ms740668%28VS.85%29.aspx):
资源暂时不可用。
此错误是从非阻塞套接字上的操作返回的无法立即完成，...
那么，这实际上意味着什么？我应该忽略该错误，重新发送邮件吗...？谢谢。
SmtpClient smtp = new SmtpClient(smtpServer);
smtp.Send(msgMail);
On second line sometimes this exception is thrown:
System.Net.NetworkInformation.NetworkInformationException:
with Message: "A non-blocking socket operation could not be completed immediately"
What does that mean? What can be the reason?
Mail sending in general is working most times.
It's a IIS7 Windows 2008 Server machine.
Thank you.
Edit:
I found something here:
http://www.thevbzone.com/modWINSOCK.bas
Public Const WSAEWOULDBLOCK = (WSABASEERR + 35) ' A non-blocking socket operation could not be completed immediately
MSDN says about this error (http://msdn.microsoft.com/en-us/library/ms740668%28VS.85%29.aspx):
Resource temporarily unavailable.
This error is returned from operations on nonblocking sockets thatcannot be completed immediately,...
So, what does that mean actually? Should I just ignore the error, resend the mail...? thanks.
