推荐答案

检查此问题的最佳方法是在代码中发送确认电子邮件。您要求用户在文本框中输入代码，然后您可以检查发送的代码是否与输入的代码相同。

发送电子邮件：

< a href =http://www.codeproject.com/Tips/163829/Sending-an-Email-in-C-with-or-without-attachments>使用或不使用附件在C＃中发送电子邮件：通用例程。 [ ^ ]

VB.NET提示：

使用或不使用附件在C＃中发送电子邮件：通用例程。 [ ^ ]

The best way to check this, is to send a confirmation email within a code. You ask the user to enter the code in a text box and then you can check whether the sent code is equal to the entered code.
To send an email:
Sending an Email in C# with or without attachments: generic routine.[^]
VB.NET tip:
Sending an Email in C# with or without attachments: generic routine.[^]
