How do I assign a value to a MailMessage ReplyTo property?

I want to set the ReplyTo value for a .NET MailMessage.

MailMessage.ReplyTo Property:

ReplyTo is obsoleted for this type. Please use ReplyToList instead which can accept multiple addresses.

MailMessage.ReplyToList Property:

Gets or sets the list of addresses to reply to for the mail message.

But, ReplyToList is ReadOnly.

I've tried to use the MailMessage.Headers property like this:

mail.Headers.Add("Reply-To", "[email protected]");

as described here: System.Web.Mail, OH MY!

But, that doesn't seem to work.

How do I set the value(s) of the MailMessage's ReadOnly property ReplyToList?

Solution

  • ReplyToList is an instance of MailAddressCollection which exposes Add method.

    To add a new address you can simply pass address as string

      message.ReplyToList.Add("[email protected]");
