You cannot use the MailAddressconstructor for specifying multiple receipts, but you can to use the MailMessageobject as showed below.

您不能使用MailAddress构造函数来指定多个收据，但您可以使用MailMessage如下所示的对象。

Using the MailMessage(notMailAddress) constructor:

使用MailMessage( notMailAddress) 构造函数：

var msg = new MailMessage("[email protected]", "[email protected], [email protected]");

another way is:

另一种方法是：

MailMessage mail = new MailMessage();
mail.To.Add("[email protected],[email protected],[email protected]");

There might be a question of why you are wanting to do this? Something like MailMessage.Tois a MailAddressCollectionwhose Addmethod is overloaded to take multiple e-mail addresses in a string, separated by a comma (see http://msdn.microsoft.com/en-us/library/ms144695.aspx).

可能会有一个问题，你为什么要这样做？喜欢的东西MailMessage.To是一个MailAddressCollection其Add方法是重载采取多个电子邮件地址中的字符串，分隔用逗号（见http://msdn.microsoft.com/en-us/library/ms144695.aspx）。

The usual use for MailAddress objects is to add them to e-mails and if you have multiple addresses then I assume you want to add them to one of the To, CC etc. fields in which case the Add overload should do you nicely. If there is something else then you are going to have to provide more context for what you are trying to do.

MailAddress 对象的通常用途是将它们添加到电子邮件中，如果您有多个地址，那么我假设您想将它们添加到 To、CC 等字段之一，在这种情况下，Add 重载应该很适合您。如果还有其他事情，那么您将不得不为您尝试做的事情提供更多背景信息。

Actually, semicolon is not a valid delimiter. Unfortunately, MSDN does not document this, had to find out this by myself.

实际上，分号不是有效的分隔符。不幸的是，MSDN 没有记录这个，必须自己找出来。

If you want to add more addresses, divide them by comma. And the space will divide display name and email address. The "To" property accepts following formats:

如果要添加更多地址，请用逗号分隔它们。并且该空间将划分显示名称和电子邮件地址。“To”属性接受以下格式：

• "[email protected]"
• "[email protected], [email protected]"
• "Name [email protected]"
• "name [email protected], [email protected]"

• “电子邮件@server.com”
• “[email protected]，[email protected]”
• “名称 [email protected]”
• “名称 [email protected]，[email protected]”

etc...

等等...

"A comma is used to separate elements in a list of mail addresses. As a result, a comma should not be used in unquoted display names in a list. The following mail addresses would be allowed" in http://msdn.microsoft.com/en-us/library/system.net.mail.mailaddress.aspx

“逗号用于分隔邮件地址列表中的元素。因此，不应在列表中不带引号的显示名称中使用逗号。以下邮件地址将被允许”在http://msdn.microsoft 中。 com/en-us/library/system.net.mail.mailaddress.aspx

Use a comma (,) as the separator instead of semicolon (;).

使用逗号 (,) 作为分隔符而不是分号 (;)。

If multiple e-mail addresses separated with a semicolon character (";") are passed in the addresses parameter. a FormatException exception is raised.

如果在addresses 参数中传递以分号字符（“;”）分隔的多个电子邮件地址。引发 FormatException 异常。

• MailAddressCollection.Add(String) 方法

This is what worked for me.

  string m_addys = "[email protected],[email protected]";
  m_message.To.Add(m_addys);

Here's another variation on this theme, FWIW:

这是这个主题的另一个变体，FWIW：

    SenderEmail = "[email protected]";
    RecipientEmail = "[email protected], [email protected], [email protected]";
    MailMessage msg = new MailMessage(SenderEmail, RecipientEmail);

Note the commas. Further details can be found at MSDN here.

注意逗号。可以在 MSDN此处找到更多详细信息。
