How to Implement Extension Methods and Lambda Expressions concepts in Linq Query

By // No comments:
Extension Methods:- The Extension Method, in .NET Framework allow you to add methods to existing types without creating a new derived type.Means You can easily extend the functionality of existing method.This is done by re-compiling and modifying the original type.
         The extension Method takes parameters in which first parameter defines the types that it extends.A class that defines the Linq extension method is called Enumerable class which is contained in the System.Linq Namespace.
Rules for Extension Methods:
  • Method must be static 
  • Method must be declared in static class.
  • Method must be taken the parameter

How to Run Linq Query Against Array and List

By // No comments:
Linq (Language Integrated Query):- It is a programming language feature through which we can link query within programming language itself.We can run link query against any data source .When we run Linq query then most of the error regarding query we get to know at compile time.

Var :-  This is a new data type which set the type of variable according to the value assign to the variable.  Means if we assign int type value in var variable then  its type will be integer,so we can not assign any other type instead of int type in var variable in whole program.
Ex.
var sname ="ABC';
Since we declare sname as var type and also assign string value("ABC") in this variable(sname) ,so its type is string,that means we can't  assign any other type value in sname variable in whole program.
Note:- You can assign any type (int,string,char,float ,etc) values in Var type variables.

Linq Query

By // No comments:
Language-Integrated Query(Ling) was Introduced as a new Component of .NET Framework 3.0. The basic
function of Linq is to add native data querying capabilities to .Net Framework by using the syntax similar to Structured Query Language(sql).
  • Linq is a programming model that is used to provide a consistent method to obtain and manipulate
    data. Linq define the set of query operators,which are used to query and filter the data.
  • In .NET Framework 4.0,Linq is used for writing efficient and multithreading queries,which is called
     PLinq (Parallel Linq).we can easily retrieve data from various data source through Linq query,
    such as Linq to Object,Linq to ADO.NET and Linq to XML.
  • A query is an expression that retrieves the requested data from a data source .Linq queries
    can also perform additional functions.such as sorting and grouping the retrieve data. The various clauses that you can use with the Linq query are the 'Form',where 'order by' and 'Select' clauses.

    There are three basic steps to execute the Linq query.
  1. Obtain the data source that can be either an Sql Database or an XML File.
  2. Create the query. 
  3. Execute the Linq Query.
