Ajax function always calling error function

Question

Hi,

 

I am trying to read messages from gmail and display them in juery datatable.

 

Ajax web method is calling error method.

 

here is the .cs code

public static void getmessage()
{
try
{
List<string> ids = new List<string>();
List<AE.Net.Mail.MailMessage> mails = new List<AE.Net.Mail.MailMessage>();
List<Email> emaillist = new List<Email>();
int count = 1;
using (var ic = new AE.Net.Mail.ImapClient("imap.gmail.com", "[email protected]", "Abc", AE.Net.Mail.AuthMethods.Login, 993, true))
{
ic.SelectMailbox("INBOX");
int y = ic.GetMessageCount();
MailMessage[] mm = ic.GetMessages(0, y);
var msgs = ic.SearchMessages(SearchCondition.Undeleted());
for (int i =0; i < msgs.Length; i++)
{
if (count == 500)
{
break;
}
string msgId = msgs[y-1].Value.Uid;
ids.Add(msgId);
y--;
count++;
}
foreach (string id in ids)
{
mails.Add(ic.GetMessage(id, headersonly: false));
}
//DataTable dt = new DataTable();
foreach (var msg in mails)
{
Email email = new Email();
Attachment attachment = new Attachment();
email.Body= msg.Body.ToString();
email.From = msg.From.ToString();
email.DateSent = msg.Date;
foreach (var att in msg.Attachments)
{
string fName;
fName = att.Filename;
string bo= att.Body;
Attachment a = new Attachment();
a.Content = fName;
email.Attachments.Add(a);
}
//dt.Columns.Add("From", typeof(string));
//dt.Columns.Add("Subject", typeof(string));
//dt.Columns.Add("Date", typeof(DateTime));
//dt.Columns.Add("Body", typeof(string));
//DataRow dr1 = dt.NewRow();
//dr1 = dt.NewRow();
//dr1["From"] = email.From.ToString();
//dr1["Subject"] = email.Subject.ToString();
//dr1["Date"] = email.DateSent;
//dr1["Body"] = email.Body;
//dt.Rows.Add(dr1);
//DataSet ds = new DataSet();
emaillist.Add(email);
}
var js = new JavaScriptSerializer();
HttpContext.Current.Response.Write(js.Serialize(emaillist));
}
}
catch (Exception exe)
{
//MessageBox.Show("Check your network connection");
}
}

here is the sample Jquery code:

$(document).ready(function () {
debugger;
$.ajax({
url: "Reademail.aspx/getmessage",
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (data)
{
debugger;
var datatableVariable = $('#tblmsg').DataTable(
{
data: data,
columns: [
{ 'data': 'From' },
{ 'data': 'Subject' },
{ 'data': 'DateSent' },
{ 'data': 'Body' }
]
});
},
error:function(){alert('error');}
});
});
