send mail using SMTP in C#

Question

Hi.

I worked with sending the mail from my app using SMTP in c#. It works Fine. But  when I am trying to retrieve the Contacts from my gmail A/C  i got the error "Execution of authentication request returned unexpected result: 404" . I tried all in google sites. the coding was same in the site which i written. 

 

i can't find the solution. i paste my code here. waiting for the help. thanks in advance.

 

try

{

RequestSettings rs = new RequestSettings("My Application", txtfromadd.Text, txtpassword.Text);

rs.AutoPaging = true;

ContactsRequest cr = new ContactsRequest(rs);

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

foreach (Contact c in f.Entries)

{

int i = 1;

foreach (EMail M in c.Emails)

{

grid.Rows.Add(false, i, M.Address.ToString());

i++;

}

}

}

catch(Exception ds)

{

MessageBox.Show(ds.Message);

}
