Serializing Objects in C#

In simple words serialization is a process of storing the object instance to a disk file. Serialization stores state of the object i.e. member variable values to disk. Deserialization is reverse of serialization i.e. it's a process of reading objects from a file where they have been stored. In this code sample we will see how to serialize and deserialize objects using C#.

NHibernate QueryOver Class And Projection....

Introduction The ICriteria API is NHibernate's implementation of Query Object . NHibernate 3.0 introduces the QueryOver api, which combines the use of Extension Methods and Lambda Expressions (both new in .Net 3.5) to provide a statically typesafe wrapper round the ICriteria API. QueryOver uses Lambda Expressions to provide some extra syntax to remove the 'magic strings' from your ICriteria queries. So, for example: .Add(Expression.Eq("Name", "Smith")) becomes: .Where<Person>(p => p.Name == "Smith") With this kind of syntax there are no 'magic strings', and refactoring tools like 'Find All References', and 'Refactor->Rename' work perfectly. Note: QueryOver is intended to remove the references to 'magic strings' from the ICriteria API while maintaining it's opaqueness. It is not a LINQ provider; NHibernate 3.0 has a built-in ...

NHibernate Introduction

NHibernate NHibernate is an open source Object-Relational Mapping (ORM) tool for the .Net platform… and the existing documentation and tutorials that I could find, whilst plentiful, are not aimed at those new to or inexperienced with ORM. This tutorial is based on using Visual Studio (I used 2008 beta 2) and Sql Server, however the database used is almost immaterial (one of the advantages of using an OR mapper). If you already know what NHibernate and ORM are and you want to use it but just need to know how? Otherwise, read on. WTF is ORM? There is plenty of good stuff out there on what Object-Relational Mapping is, try wikipedia or the intro here (the tutorial is a bit out of date but the explanation is good) or there’s always Google . However, in a nutshell, ORM is the process of mapping business objects (think OOP) to database relations (read tables). An OR Mapper is a tool that manages this process. There are several different OR Mappers available for ...

Understanding machine learning

What is machine learning does? It Finds patterns in data and uses those patterns to predict the future. EXAMPLES : Detecting credit card fraud : You can use machine learning detect credit card fraud, Suppose you have data about previous credit card transactions. You could find patterns in that data potentially that allows you to detect when a new credit card transaction is likely to be fraudulent. Determining whether a customer is likely to switch to a competitor : You could possibly find the patterns in the existing customer data that will help you do that Lots more What does it mean to learn ? Yes it's something like your own learning process. You have learned reading,listening, walking everything by using your experience on it, the data you have in your mind and continuous improvements. How did you learn to read? Well learning requires identifying patterns. Reading for instance you ...
