WindowsフォームのGmail

Question

Windowsアプリケーションでメールを受信するためのGoogleによるサービスはありますか？そうでない場合は、同じものを開発するための簡単な説明を教えてください。

ありがとうございます。

Answer 1

これは私のGmailの受信トレイを読むために開発したクラスです。

public class GmailClient : IDisposable 
{ 
    private const string GmailUri = "https://mail.google.com/mail/feed/atom"; 
    private string _userName; 
    private string _password; 
    private GmailList _newMailList; 

    public GmailClient(string userName, string password) 
    { 
     _userName = userName; 
     _password = password; 
    } 
    /// <summary> 
    /// I'd prefer to return the generic list here instead of using the GetMailItem 
    /// method to get individual items, but javascript doesn't play nice with generics. 
    /// </summary> 
    public void GetUnreadMail() 
    { 
     try 
     { 
      // Get the XML feed from mail.google.com 
      XmlElement element = GetFeedXml(); 

      if (element != null) 
      { 
       // Deserialize the transformed XML into a generic list of GmailItem objects 
       XmlNodeReader reader = new XmlNodeReader(element); 
       XmlSerializer serializer = new XmlSerializer(typeof(GmailList)); 

       _newMailList = serializer.Deserialize(reader) as GmailList; 
      } 
     } 
     catch { } 
    } 
    /// <summary> 
    /// The number of items in the unread mail collection 
    /// </summary> 
    public object UnreadMailCount 
    { 
     get 
     { 
      if (_newMailList != null) 
      { 
       return _newMailList.Count; 
      } 
      else 
      { 
       return 0; 
      } 
     } 
    } 
    /// <summary> 
    /// Returns the GmailItem at the specified index 
    /// </summary> 
    /// <param name="index">Index if the mail item to return</param> 
    public GmailItem GetMailItem(int index) 
    { 
     if (_newMailList == null || index < 0 || index > _newMailList.Count) 
     { 
      throw new IndexOutOfRangeException(); 
     } 

     return _newMailList[index]; 
    } 
    /// <summary> 
    /// Get the XML feed from google and transform it into a deserializable format 
    /// </summary> 
    private XmlElement GetFeedXml() 
    { 
     try 
     { 
      // Create a web request to get the xml feed 
      HttpWebRequest request = (HttpWebRequest)WebRequest.Create(GmailUri); 
      request.Method = "GET"; 
      request.Credentials = new NetworkCredential(_userName, _password); 

      XmlDocument xml = null; 
      HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 

      // If the request/response is successful 
      if (response.StatusCode == HttpStatusCode.OK) 
      { 
       // Get the response stream containing the xml 
       using (XmlTextReader reader = new XmlTextReader(response.GetResponseStream())) 
       { 
        // Load the XSLT document (it's an embedded resource) 
        byte[] data = Encoding.ASCII.GetBytes(GmailReader.Properties.Resources.GmailTransform); 

        using (MemoryStream xsltStream = new MemoryStream(data)) 
        { 
         // Create a text reader with the XSLT document 
         XmlTextReader stylesheetReader = new XmlTextReader(xsltStream); 

         XslCompiledTransform transform = new XslCompiledTransform(); 
         transform.Load(stylesheetReader); 

         // Run an XSLT transform on the google feed to get an xml structure 
         // that can be deserialized into a GmailList object 
         using (MemoryStream ms = new MemoryStream()) 
         { 
          transform.Transform(new XPathDocument(reader), null, ms); 
          ms.Seek(0, SeekOrigin.Begin); 

          xml = new XmlDocument(); 
          // Load the transformed xml 
          xml.Load(ms); 
         } 
        } 
       } 
      } 

      response.Close(); 

      return xml.DocumentElement; 
     } 
     catch 
     { 
     } 

     return null; 
    } 

    #region IDisposable Members 

    public void Dispose() 
    { 
     // Nothing to do here. 
    } 

    #endregion 
}} 

私はそれが今ここにある1以上のクラスを追加するのを忘れて申し訳ありませんが....

using System; 
using System.Collections.Generic; 
using System.Runtime.InteropServices; 

namespace GmailReader 
{ 
    [Serializable, 
    ComVisible(true)] 
    public class GmailList : List<GmailItem> 
    { 
     public GmailList() { } 
    } 
[Serializable, 
ComVisible(true)] 
public class GmailItem 
{ 
    public GmailItem() { } 

    public string Title; 
    public string Summary; 
    public string Link; 
    public string AuthorName; 
    public string AuthorEmail; 
    /*public DateTime Issued; 
    public DateTime Modified;*/ 
    public string ID; 
} 

}

Answer 2

POP3またはIMAPアプリケーションを作成するだけです。ここにはIMAPを介してGmailにアクセスすることを扱うquestionがあります。

Answer 3

POP3またはIMAPプロトコルでGmailアカウントに接続できます。 Googleでは読み取り専用の受信ボックスフィードAPIも提供しています：http://code.google.com/apis/gmail/docs/inbox_feed.html
