That is, Lambda Expression only provides the facility to specify the syntax of the Anonymous Method in a simple way. In place of the Anonymous Method, we can also use Lambda Expressions, which is more convenient to use than Anonymous Methods.

LINQ Lambda Expressions Syntax 

(Input Parameter) => Method Expression

Lambda Expression is dynamic variable and decides the type in compile time.

 intAry.Where( x => x%2 == 0 );

in this example x is dynamic variable, and this expression { x%2 == 0 } check the x is even or odd.

Example 

using System;
using System.Linq;
using System.Collections.Generic;
class MyProgram
{ 
    static void Main(string[ ] args)
    { 
      int[] intAry = {45,78,5,896,4,5,8,65,99,66,55,88,5,558,56,55,45,23};
      Console.WriteLine('Even list ');
      var Evenlist = intAry.Where( x => x%2 == 0 ); 
      Evenlist.ToList().ForEach(x => Console.Write(x+ ', '));

      Console.WriteLine('\nOdd list ');
      var Oddlist = intAry.Where( x => x%2 != 0 );
      Oddlist.ToList().ForEach(x => Console.Write(x + ', '));
    } 
}

Output

Even list 
78, 896, 4, 8, 66, 88, 558, 56, 
Odd list 
45, 5, 5, 65, 99, 55, 5, 55, 45, 23,
