使用C＃.Net Gmail API，为什么我不能在收件箱中打印电子邮件数量？

Question

Im experimenting with the gmail api in C#.

My code looks like this:

UsersResource.MessagesResource.ListRequest request = service.Users.Messages.List("me");

                Console.WriteLine("Count Message: ");

                IList messages = request.Execute().Messages;

                if (messages != null && messages.Count > 0)
                {
                    foreach (var message in messages)
                    {
                        Console.WriteLine(message);
                    }
                }

It returns Google.Apis.Gmail.v1.Data.Message, 100 times. I understand that there are apperently 100 message in messages, but why? Im so confused.

Answer 1

message is a class (not a string) and Console.WriteLine(message); would call and print it's .ToString() method which would lead to what you are currently seeing.

Here you can find more about its properties. you may want to print its Raw property which is base64string of the message:

  foreach (var message in messages)
  {
        string body = Encoding.UTF8.GetString(Convert.FromBase64String(message.Raw));
        Console.WriteLine(body);
  }
