C# Lambda Expression

In this blog I try to introduce Lambda expression with simple language and syntax. I hope after reading this blog you will be able to use lambda expression to write anonymous method in your code.I would like to have feedback from blog readers.

Introduction

Lambda Expression concept was introduced in C# 3.0 . Lambda expression can be assumed as a more concise syntax of anonymous method. Anonymous methods can be written with C Sharp Lamda Expression. At the time of Compilation lambda expression converted in anonymous method , It is a Lambda expression conversion rule. On Left side of Lambda operator “=>” represent the argument to the method and on right side method body.

Syntax
(parameters) => expression or _statement block

Types

There are basically 2 types of Lambda expression

1. Statement Lambda: It has a statement block on the right side of lambda operator “=>”

for example i=> (return i*I ;);

2. Expression Lambda: It has only an expression k=>k*k; // here k*k is expression

Features

1. Lambda expression does not have type. In CLR there is no concept of Lambda.
2. Jump statements are not allowed within anonymous method/lambda expression.
3. Lambda expression generally used with the Function and action Delegate.
4. Variables which are defined within a lambda expression , has the scope only within the Lambda expression body.
