Exception Handling

[YudhiTiger]

HI,

my asp.net project has 3 tier (UI, BLL, DAL) architecture. can any body tell me the best way to handle the exception.

will appreciate your help

It depends on what kind of exception it is. If it's something the user can do something about, such as invalid input, then re-throw the exception in the BLL and/or DAL and catch in the UI and display a message to the user. If the user cannot correct the problem, then catch it in the Application_Error event and write detailed information to a log to help you debug it. Then decide whether the application can continue silently, or whether you must tell the user that something went wrong.

you can do this in your DLL functions..

eg.,


internal DataSet fun(BLL objBL)
{
try
{
//your connection, procedures here...
}
catch(Exception ex)
{
ex.Message(); // can display this message in your page by converting this as session object
}
finally
{

}
return ds;

}


hope this may help for u.....


Cheers..
