    List<Employee> GetAllEmployeesMethod(); 

    [OperationContract] 
    string TestMethod(); 

    [OperationContract] 
    [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "players")] 
    List<Person> GetPlayers(); 

} 

---- ---- Service1.svc.cs

public List<Employee> GetAllEmployeesMethod() 
{ 
    List<Employee> mylist = new List<Employee>(); 

    using (SqlConnection conn = new SqlConnection("--connection string--")) 
    { 
     conn.Open(); 

     string cmdStr = String.Format("Select customercode,CurrencyCode,CurrencyDesc from Currency"); 
     SqlCommand cmd = new SqlCommand(cmdStr, conn); 
     SqlDataReader rd = cmd.ExecuteReader(); 

     if (rd.HasRows) 
     { 
      while (rd.Read()) 
       mylist.Add(new Employee(rd.GetInt32(0), rd.GetString(1), rd.GetString(2))); 
     } 
     conn.Close(); 
    } 


    return mylist; 
}
