Exception inside dll
-
i have written a database application in c#, the application use another c# dll to connect with the database. I am getting some exception inside the c# dll( i have not include exception handling inside the dll), but those exceptions are not being caught from the application. for example
try { DatabaseManager db = new DatabaseManager(); db.Execute(); } catch ( Exception ex ) { // log exception }here the DB.Execute() is crashing inside the dll but not capturing in application.What could be the reason?

Hi here the Execute method is crashing...... Here my problem is that my application is not able to catch that exception.( those exceptions occurs inside the dll)

Because you've swallowed the exception (and logged it according to your comments) rather than rethrowing it.
try
{
// whatever
}
catch(Exception ex)
{
// log exception
throw;
}now the calling application will receive the exception.
There may be some mistake in my question .let me explain it once more.... <pre> try { // This function is inside the DLL Function(); } catch ( Exception ex ) { // Log exception } //Inside the DLL public void Function() { // something which is crashing....... } what i am saying is i am not getting the exception which is occuring inside the dll....

from my experience, in that row, the dll create a new thread, and the new thread throw an exception.
There is no new thread created in that code.

For what????? Hi all please understand my question.............. 1. I am calling a method from an application ( example APP) ,which is inside a dll( example DLL) 2. Just assume that that method is crashing( in side DLL) 3. I want to catch the exception in the calling application( APP)( the application from which i called the dll method) ---------------------------------------------------------------------

"if you cannot catch the exception from method Execute, that means there is something wrong in the method." please try to understand that i dont want to find the root cause or reason for the exception... i want to catch the exception in the c# application which calls the DLL............. Please imagine that i put some code which generates exception.I dont want to debug and find the reason i just want to catch it on my application...
