public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void btnSubmit_Click(object sender, EventArgs e)

        DataSet ds = new DataSet();
        ds.Tables.Add("GmailContacts");
        ds.Tables[0].Columns.Add("EmailId");

        RequestSettings rs = new RequestSettings("Idea Elan2", txtUserName.Text, txtPassword.Text);
        rs.AutoPaging = true;

        ContactsRequest cr = new ContactsRequest(rs);

        Feed<Contact> f = cr.GetContacts();

        foreach (Contact contact in f.Entries)
        {
            foreach (EMail email in contact.Emails)
            {
                DataRow row = ds.Tables[0].NewRow();
                row["EmailId"] = email.Address.ToString();
                ds.Tables[0].Rows.Add(row);

            }            
        }

        GridView1.DataSource = ds.Tables[0];
        GridView1.DataBind();
        lblstatus.Text = "Total Contacts For" + txtUserName.Text + ":" + ds.Tables[0].Rows.Count.ToString();

        
    }
}

foreach（f.Entries中的联系方式）在这里它自我我得到错误你可以请求这是问题和错误是无效的凭证
