Setting and getting message headers

You can add custom headers to a MimeMessage by invoking the AddHeader method and passing it a MimeHeader instance. Custom header names generally start with an "X" followed by a hyphen and a header name.

Example

This example first sets a custom header then displays the header value.

[C#]

MimeHeader agent = new MimeHeader("X-Mailer", "Microsoft Outlook");

message.AddHeader(agent);

// displays Microsoft Outlook

Console.WriteLine(message.GetHeaderValue("X-Mailer"));

[Visual Basic]

Dim agent As MimeHeader = Nothing

agent = New MimeHeader("X-Mailer", "Microsoft Outlook")

message.AddHeader(agent)

' displays Microsoft Outlook

Console.WriteLine(message.GetHeaderValue("X-Mailer"))
