<a href=""https://example.com/register-confirm"">点击确认注册</a>
";
WebMail.Send(

5. Send email and handle exception
In practical applications, various abnormal situations may occur when sending emails. To ensure reliable email delivery, we need to handle exceptions appropriately. Here is an example showing how to send mail and handle exceptions:

subject: "测试邮件",
body: "这是一封测试邮件。"
);

Response.Write("邮件发送成功！");
}
catch (Exception ex)
{
// 处理邮件发送失败的异常
Response.Write("邮件发送失败：" + ex.Message);
}
}
In the above code, we use try-catchblocks to catch exceptions that may be thrown during email sending. In catchthe block, we can handle the case where the mail delivery fails and output the appropriate error message.
