Question

if I do this:

try 
{
    //code
}
catch (Exception)
{
    throw;
}

Does the Exception go up with all its information?
The idea is to handle errors at the top of the app. There I’d execute some SQL sp to fill the admin’s table so he’s aware of exceptions.

I want to store Exception.Message and the source (method, function, whatever..) of the exception. But I don’t know how to refer to “where” the exception happened. Is it Exception.Source? Exception.TargetSite?

Thanks.

The type of Exception will tell you what kind of exception it is (IndexOutOfRangeException, SqlException, etc) which you would react too accordingly:

try 
{
    //code
}
catch (SqlException ex)
{
    // Handle code
}
catch (IndexOutOfRangeException ex)
{
    // Handle code
}
catch (Exception ex)
{
    // Handle code
}

As to where it is happening… you should be enclosing exception-prone areas with a try catch and not large code chunks. This way you will know where the exception derives from.
