C# forward a gmail message to another email address

Question

My goal is to retrieve all emails that exist under one label within my gmail account and forward those emails to another email address. Here's what i have so far:

string[] Scopes = { GmailService.Scope.GmailReadonly, GmailService.Scope.GmailSend, };
string ApplicationName = "APP NAME";
UserCredential credential;
using (var stream = new FileStream("credentials.json", FileMode.Open, FileAccess.Read))
{
    string credPath = "token.json";
    credential = GoogleWebAuthorizationBroker.AuthorizeAsync(   
           GoogleClientSecrets.Load(stream).Secrets,
                    Scopes,
                    "user",
                    CancellationToken.None,
                    new FileDataStore(credPath, true)).Result;
                Console.WriteLine("Credential file saved to: " + credPath);
}
var service = new GmailService(new BaseClientService.Initializer()
{
    HttpClientInitializer = credential,
    ApplicationName = ApplicationName,
});

var labelList = service.Users.Messages.List("me@gmail.com");
labelList.LabelIds = "LABEL_NAME";
var emailListResponse = labelList.Execute();
if (emailListResponse != null && emailListResponse.Messages != null)
{
    foreach (var email in emailListResponse.Messages)
    {
       //THIS IS WHERE I WOULD LIKE TO FORWARD this email TO ANOTHER EMAIL ADDRESS?
       //How to set TO?
       //service.Users.Messages.Send(email, "me@gmail.com").Execute();
    }
}

I am able to retrieve the emails but i'm not sure how to forward. Thank you for your help

i definitely thought there would be an easier way just to forward the exiting message but it doesn't look that way. Thanks for this link — user2370664, Nov 14 '19 at 15:29

To forward a message you have to get it and add the recipient's email to the "To:" field.

Alternatively, you could set up a filter to forward all emails with the Label you have to another address.

i understand that i need to add the forward recipient to the TO field. How? – user2370664 Nov 14 '19 at 14:22
it appears using a filter would only forward new incoming email. New email would not have the label yet – user2370664 Nov 14 '19 at 14:32
