System.Net.Mail.MailAddress使用一个参数发送到多封电子邮件

Question

I've just switched from the deprecated System.Web.Mail.MailAddress to System.Net.Mail.MailAddress , but it doesn't seem to be particularly flexible when passing in a parameter holding multiple addresses when using the new System.Net.Mail.MailAddress.To.Add .

string emailAdd= "email1@emailus.com; email2@emailus.com";

System.Net.Mail.MailAddress.To.Add(emailAdd);

In the above example, email2@emailus.com is emailed successfully, but email1@emailus.com is not. I really need a way to do this since my addresses are defined in another class and passed to an email() method via a parameter. I'm simply not passing five parameters for 5 separate emails. Or indeed one and splicing on my end, .Web version is proving to be way more versatile.

This question is not a duplicate of the suggested one. The answer to the "duplicate" is add them individually, I want to add multiple addresses simultaneously. Since there is a way to do this, this question is more relevant than the one I'm accused of duplicating.

Answer 1

According to MSDN , the .Add() method accepts a string of comma-delimited addresses, rather than colon-delimited.

Therefore either changing the parameter that you are passing in to a comma-delimited string, if possible, or adding functionality to your email method to replace the colons with commas should resolve the issue.

Answer 2

为此，您可以遵循实际上表示的功能参数，这表明您可以使用逗号定界符，而功能参数则表示为地址，该地址标识您可以使用该地址一起发送多封电子邮件

mail.To.Add("to1mailaddress@domain,to2mailaddress@domain");
