I have following classes , DBConn for database connection , UserBL class for handle external user functionality , SpeakerVO class for handle the entity properties, SpeakerBL class for handle the business layer methods, ICustomerService for service layer interface, CustServiceManager class for handle the service layer methods
the issue is when you call the service layer method passing User class appropriately , but still CustServiceManager class, ViewAll method the _user parameter becomes null
client calling code in windows application is below
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
UserBL _user = new UserBL();
string ConStrng = ConfigurationSettings.AppSettings["ConnectionString1"];
_user.SetConnection(ConStrng);
SpeakerReference.CustomerServiceClient x = new SpeakerReference.CustomerServiceClient();
x.ViewAll(_user);
}
}
