发送邮件到多个收件人时如何修复异常？ [英] How to fix exception thrown when sending mail message to multiple recipients?

问题描述

在下面的代码片段中，我在'this.Recipients'上得到一个FormatException。更具体地说，消息是在邮件头中找到无效的字符：';'。

In the code snippet below, I'm getting a FormatException on 'this.Recipients'. More specifically, the message is "An invalid character was found in the mail header: ';'".

收件人是一个由三个电子邮件地址组成的字符串，以分号分隔（ ';'字符）。收件人列表从app.config中读取，数据正在进入收件人变量。

Recipients is a string of three email addresses separated by semicolons (the ';' character). The list of recipients is read from an app.config and the data is making it into the Recipients variable.

如果多个收件人应该分开，我该如何收到此错误用分号？有什么建议么？一如往常，谢谢你的帮助！

How can I be getting this error when multiple recipients should be separated by a semicolon? Any suggestions? As always, thanks for your help!

public bool Send()
{
    MailMessage mailMsg = 
       new MailMessage(this.Sender, this.Recipients, this.Subject, this.Message);

    SmtpClient smtpServer = new SmtpClient(SMTP);
    smtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;

编辑＃1 - 这个表示使用分号。

Edit #1 - This says use a semicolon.

推荐答案

我看不到 MailMessage构造函数文档中的任何内容建议您可以指定多个收件人。我建议您创建 MailMessage 对象，然后分别添加每个电子邮件地址。

I can't see anything in the MailMessage constructor documentation to suggest you can specify multiple recipients like that. I suggest you create the MailMessage object and then add each email address separately.

请注意， MailAddressCollection.Add 方法被记录为接受逗号 -separated地址...所以它可能可以在构造函数中工作。

Note that the MailAddressCollection.Add method is documented to accept comma-separated addresses... so it's possible that that would work in the constructor too.
