ok pls chek this, I m getting the same error:

service1.svc.cs code is:

public class Service1 : IService1
{
BussinessMobileWeb _obj = new BussinessMobileWeb();
[WebMethod]
public List<t_country_cmn> getcountrybyid()
{
DataTable dt = _obj.CountryList();
var lstGridData = new List<t_country_cmn>(dt.Rows.Count);
lstGridData.AddRange(from DataRow in dt.Rows
select new t_country_cmn(row[country_name],
row[country_desc],
row[country_telecom_code],
row[date_format],
row[fnb_type_sk],
row[country_code],
row[is_sms_notification],
row[distance_measurement_unit]));
// List rows = dt.Rows.Cast().ToList();
return lstGridData.ToList();
}
}


my iservice.cs code is:

namespace JSONWebService
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
[ServiceContract]
public interface IService1
{[OperationContract]
[WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "GetAllCountries")]
List<t_country_cmn> getcountrybyid();
}


my customer.cs file where I have declared t_country_cmn class

namespace JSONWebService
{
[DataContract]
public class t_country_cmn
{

//t_country_cmn(int country_sk, int currency_sk, string country_name, string country_desc, string country_telecom_code, string date_format, string fnb_type_sk, string country_code, string is_sms_notification, string distance_measurement_unit);

[DataMember]
public int country_sk { get; set; }

[DataMember]
public int currency_sk { get; set; }

[DataMember]
public string country_name { get; set; }

[DataMember]
public string country_desc { get; set; }

[DataMember]
public string country_telecom_code { get; set; }

[DataMember]
public string date_format { get; set; }

[DataMember]
public string fnb_type_sk { get; set; }

[DataMember]
public string country_code { get; set; }

[DataMember]
public string is_sms_notification { get; set; }

[DataMember]
public string distance_measurement_unit { get; set; }
}
}

thnks RelicV, I tried ur code

[WebMethod]
public List<t_country_cmn> getcountrybyid()
{
DataTable dt = _obj.CountryList();
var lstGridData = new List<t_country_cmn>(dt.Rows.Count);
lstGridData.AddRange(from DataRow in dt.Rows
select new t_country_cmn(row[country_name],
row[country_desc],
row[country_telecom_code],
row[date_format],
row[fnb_type_sk],
row[country_code],
row[is_sms_notification],
row[distance_measurement_unit]));
// List<t_country_cmn> rows = dt.Rows.Cast<t_country_cmn>().ToList();
return lstGridData;
}


I am getting following error, suggest me what is wrong in this:

Error 1 Could not find an implementation of the query pattern for source type 'System.Data.DataRowCollection'. 'Select' not found. Consider explicitly specifying the type of the range variable 'DataRow'. /Service1.svc.cs

Also I would like to ask u if there is a way to get data from database directly into the list type or any other type to return json?? At present I m getting data from database into data table and then... as u can see in the above code I have pasted. My priority is to make the web service as fast as possible.

FB.logout(function(response) {
// user is now logged out
});

i have written the above code on my .aspx page, and called the above script on my websites sign out button click event, but its not working.

I have written the code

FB.logout(function(response) {
// user is now logged out
});

on my aspx page bt nothing happens.
i think i m missing something so if u can give me an example, it will help me more.
