C# new MailMessage()抛出';句柄无效';
为什么该代码:C# new MailMessage()抛出';句柄无效';,c#,asp.net,asp.net-4.0,system.net.mail,C#,Asp.net,Asp.net 4.0,System.net.mail,为什么该代码: MailMessage mm = new MailMessage(); 抛出此异常: System.Security.Cryptography.CryptographicException was caught Message=The handle is invalid. Source=mscorlib StackTrace: at System.Security.SecureString.ProtectMemory() at System.Security.Se
MailMessage mm = new MailMessage();
抛出此异常:

我的Web.config
<smtp deliveryMethod="Network" from="correctAddress">
<network host="smtp.gmail.com" userName="correctAddress" password="correctPassword" enableSsl="true" port="587"/>
</smtp>
我相信实例化邮件消息不会从Web.config读取。SmtpClient读取web.config中设置的SMTP
你能展示更多你的代码吗?可能是GetMailMessage方法的其余部分。为什么会抛出它?可能是因为MS在幕后做了些傻事 IIRC,该SecureString代码实际上对advapi32.dll进行了互操作调用 我的下意识反应是:
你的web.config在smtp部分说了什么?real answer
MS在幕后做了一些傻事
它今天神奇地工作得很好。
