推荐答案

查看 MailAddress重载 [ ^ ]：

Look at the MailAddress overloads[^]:

msg.From = new MailAddress(fromAddress, fromDisplay, Encoding.UTF8);

这可能会解决您的问题。

有一个通用的电子邮件例程，它在这里完全正常工作：使用或不使用附件在C＃中发送电子邮件：通用例程。 [ ^ ] - 那个也可以帮助你理解。

That may solve your problem.
There is a generic Email routine which is fully working here: Sending an Email in C# with or without attachments: generic routine.[^] - that may also help you understand.
