WPF 应用程序在发送电子邮件时停止工作并出现 CLR20r3 错误

Question

我有使用 .NET 3.5 开发的 WPF 应用程序。我尝试在 Windows Vista PC 上运行应用程序。应用程序正常运行ning 直到它需要发送电子邮件的部分，然后应用程序停止并出现以下错误：

Description:
Stopped working

Problem Signature:
Problem Event Name: CLR20r3
Problem Signature 01:   yesmonitor.exe
Problem Signature 02:   1.0.0.0
Problem Signature 03:   54c730d7

OS Varsion: 6.0.6002.2.2.0.768.2
Local ID:   1037

我还在 PC 上安装了 .NET 3.5 框架：

Visual C++ Redistributable 2013
Visual C++ Redistributable 2012
Visual C++ Redistributable 2008
Visual C++ Redistributable 2005

我的发送邮件代码是：

MailAddress From = new MailAddress("mymail", strIsTestPass + " - " + errorType);
MailMessage mail = new MailMessage();

mail.From = From;
mail.BodyEncoding = Encoding.UTF8;
mail.IsBodyHtml = true;
mail.To.Add("mymail");
mail.Subject = "subject";
mail.Body = "body";
SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
NetworkCredential basicCredential = new     NetworkCredential("mail", "password");
smtp.Credentials = basicCredential;
smtp.EnableSsl = true;
smtp.Send(mail);

顺便说一下它在 Win7 OS PC 上的工作方式。可能是什么问题，我该如何解决？

Answer 1

将您的代码放入 try catch 并将您的 google 帐户设置 "Access for less secure apps" 设为开启。

try
{
    MailMessage mail = new MailMessage();
    SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");

    mail.From = new MailAddress("example@gmail.com");
    mail.To.Add("example@gmail.com);
    mail.Subject = "email subject";
    mail.Body = "Email body here";
    SmtpServer.Port = 587;
    SmtpServer.Credentials = new System.Net.NetworkCredential("mail", "password");
    SmtpServer.EnableSsl = true;
    SmtpServer.Send(mail);
}
catch (Exception)
{

    throw;
}
