.Net and Deep Copy

October 8, 2007January 31, 2020 Gunnar Peipman 616 Views 8 Comments

Some time ago I had to clone objects and .Net’s shallow copy proved to be insufficient – it was necessary to use deep copy. No good tools are provided by .Net itself. If required, the object to be cloned must conform to the ICloneable interface and the Clone() method can be defined for the object. As the classes were not very numerous, but relatively bulky and complicated, there was no point in writing a Clone() method for all of them. I needed something else.

Exporting GridView Data to Excel

My current project required a way for exporting data to Excel. I could of course write a separate export method for every data set but in my opinion it would be a pointless waste of time. I would also like to utilise the existing functionality as much as possible – as it is, the lists going to Excel are displayed to the user in the browser.
