The GMail component provides an easy way to manage sending and receiving mail in Gmail.

Syntax

nsoftware.CloudMail.Gmail

Remarks

This class provides an easy to use interface for Gmail using version 3 of the Gmail REST API. To use the class, first set the Authorization property to a valid OAuth token. The GMail class can be used for sending or creating new messages; retrieving existing messages; creating, deleting, or sending drafts; and several other functionalities supported by the Gmail API.

This class requires authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth class or a separate process. Once complete you should have an authorization string which looks like:

Bearer ya29.AHES6ZSZEJzATdZYjeihDn5W-VrXSsxEZu5p0pclxGdKKQ

Assign this value to the Authorization property before attempting any operations. For Example:

Oauth oauth = new Oauth();
 
oauth.ClientId = "3c65828c-6376-4286-91b5-2381c3904a97"; 
oauth.ClientSecret = "mkk2a2M-B5TQI7o5p_N0fR-CHYVn7e3yH~";
oauth.AuthorizationScope = "https://www.googleapis.com/auth/gmail.readonly";
oauth.ServerTokenURL = "https://accounts.google.com/o/oauth2/token";
oauth.ServerAuthURL = "https://accounts.google.com/o/oauth2/auth";
oauth.GrantType = OauthGrantTypes.ogtAuthorizationCode;
 
gmail.Authorization = oauth.GetAuthorization();
Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.

Sending Messages

There are two methods for sending messages using the Gmail component. The SendMail method will send a message directly. Alternatively, you can create a message draft and then send an existing draft using the SendDraft method. In both cases the properties of the new message are assigned through the Message properties (MessageSubject, MessageBodyContent, MessageCc, etc.).

Sending a Message with SendDraft:

gmail.MessageSubject = "I am sending an email.";
gmail.MessageBodyContentType = "TEXT";
gmail.MessageBodyContent = "Just wanted to let you know.";
gmail.MessageTo = "reader@tautology.org";

gmail.CreateDraft();
string messageId = gmail.MessageInfo[0].Id;

gmail.SendDraft(messageId);

Receiving Messages

Information about messages fetched by the component can be accessed through the MessageInfo* properties. The MessageInfo* properties is populated when the ListMessages, FetchMessageInfo, or Search methods are called.

The ListMessages method will list the messages.

By default, the component will fetch one page of 100 messages when ListMessages is called. If additional messages remain in the folder, the NextPageToken property will be populated. If ListMessages is then called again on the same folder the next page of messages will be fetched. The example below populates the MessageInfo* properties with all the messages in the mailbox.

do {
  gmail.ListMessages("", "");
} while (gmail.NextPageToken.Length > 0);

The message page size may also be changed by using the MessagePageSize configuration setting.
