Is there posibility to create clone of an object without using
serialization, create instance and copy, reflection ?
I have a problem with DataColumnColec tion which is member of DataTable
(Columns - property). I found that constructor of Typed DataSet with
Typed DataTable takes long time :/ I tried to investigate this problem
and found that adding columns to Columns (even if I use AddRange)
(typeof DataColumnColle ction) is very slow because it invokes:
this.table.Upda tePropertyDescr iptorCollection Cache();
which has a loop which do the same operations n(n+1)/2 times. This loop
should be invoked only once when EndInit is invoked on DataTable :/
Creation of 1000 of typed DataSets takes me now 1,3 sec (this is very
slow because we utilize DataSets during transactions... )
So i try to found out faster way to create typed DataTable
(serialization, cloning ????) to reduce cost of constructor
Is there any way to do this ?

DataSet implements both 'Clone' & 'Copy' method does these not provide what
you want?
I am not sure how these will work with a strongly typed DataSet though.

| 4 2457 Learning PHP (5) -> cloning objects? by: Tom |last post by: Hey ho, The release of PHP5 seemed like a good reason to try to learn it once more... I'm reading through the O'Reilly PHP/MySQL book and right now, I'm fiddling with objects.

| 3 8746 Why deep cloning? Why shallow cloning? How is this related to references? by: raylopez99 |last post by: The "C# Cookbook" (O'Reilly / Jay Hilyard), section 3.26, is on deep cloning versus shallow cloning. The scanned pages of this book are found here: http://www.sendspace.com/file/mjyocg (Word format, 3 pp) My question, coming from a C++ background where deep copying is done, is why in C# you would do either deep or shallow copying as suggested by O'Reilly (using the "ICloneable" inhereited interface), at least for the .NET framework. ...
