调试易

里面的代码现在  获取不了  gmail联系人 了
不知道为什么 ，原来确实可以的。
代码如下public class GmailExtract : IMailContactExtract
    {
        private const string ContinueUrl = "http://mail.google.com/mail?ui=html&zy=l";
        private const string ExportUrl = "https://mail.google.com/mail/contacts/data/export?exportType=ALL&groupToExport=&out=GMAIL_CSV";
        private const string LoginRefererUrl = "https://www.google.com/accounts/ServiceLogin?service=mail&passive=true&rm=false&continue=http%3A%2F%2Fmail.google.com%2Fmail%2F%3Fui%3Dhtml%26zy%3Dl&ltmpl=default&ltmplcache=2";                private const string LoginUrl = "https://www.google.com/accounts/ServiceLoginAuth?service=mail";
        private const string UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; EmbeddedWB 14.52 from: http://www.bsalsa.com/ EmbeddedWB 14.52; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.1; .NET CLR 1.0.3705; .NET CLR 3.0.04506.30)";
        
        #region IMailContactExtract Members
        
        public bool Extract( NetworkCredential credential, out MailContactList list )
        {
            bool result = false;
            list = new MailContactList();            try
            {

Google开放了相关的API
楼主看这里：
Google Contacts Data APIhttp://code.google.com/apis/contacts/docs/2.0/developers_guide_dotnet.html#retrieving_without_query

项目添加dll引用：
Google.GData.Client.dll
Google.GData.Contacts.dll
Google.GData.Extensions.dll using System;
using Google.Contacts;
using Google.GData.Client;
using Google.GData.Contacts;
using Google.GData.Extensions;namespace ConsoleApplication9 {
    class Program {
        static void Main() {
            RequestSettings rs = new RequestSettings("", "[email protected]", "yourpassword");
            // AutoPaging results in automatic paging in order to retrieve all contacts
            rs.AutoPaging = true;
            ContactsRequest cr = new ContactsRequest(rs);            Feed<Contact> f = cr.GetContacts();
            foreach (Contact contact in f.Entries) {
                Console.WriteLine("\t" + contact.Title);
                foreach (EMail email in contact.Emails) {
                    Console.WriteLine("\t" + email.Address);
                }
                foreach (GroupMembership g in contact.GroupMembership) {
                    Console.WriteLine("\t" + g.HRef);
                }
                foreach (IMAddress im in contact.IMs) {
                    Console.WriteLine("\t" + im.Address);
                }
            }
            Console.ReadLine();
        }
    }
}
