Best Practices: Avoid using DataTables

DataTables will take huge memory like multiples of actual needed. So try to use Plain Old Class Objects and DataReader.

String to Number, DateTime and Boolean conversion

.Net value type classes mostly have a built in static method Parse to convert a String to specific data types.

Example:

Integer.Parse

Long.Parse

Decimal.Parse

Boolean.Parse

DateTime.Parse

Object. ToString method

Object is the base class for all the .Net data types

It has one important method ToString which basically can give the string representation of an Object. Implementation of ToString in Object class basically returns the Type name of the given object. When we call ToString on a class that does not override ToString will just return Type name of the given object.
