Why would you want to write something that was not extensible. I know
it is
a value type but is the overhead worth the symantic sacrifice?
a struct is allocated on the stack ... a class is allocated on the heap ...
So "i believe" that, when you quit the scope of the stack, the struct is
destroyed and not available ... (to be confirmed)

Subject: [ADVANCED-DOTNET] New Type decision Criterias

Hi All,
I have to read a fixed length file which has about 52000 entries and
store
these entries into a database table. I have created a new type and it
has
properties which are mapped to the columns in the file. I have created a
collection class to store all the instances. The collection class
inherits
from the CollectionBase class. Therefore, internally I am adding all the
instances to the ArrayList.
I am just thinking about whether I should be creating the new type as a
struct or a class i.e. value type or reference type. I am asking this
just
to check on the performance as it has very large number of entries in
it.
The type has some 19 fields out of which 2 are DateTime, 2 integers
and one
char, and rest are string values.
Kindly suggest
Thanks in advance,
Regards,
Girish Jain
