										 |  |  | The If-Else statement executes a block of code depending on whether your precondition is fullfilled or not. |

							|  |  |  | ## Example
 | 
					
						
							|  |  |  | ``` | 
					
						
							|

										 |  |  | 
 | 
					
						
							|  |  |  | if(boolean expression) | 
					
						
							|  |  |  | { | 
					
						
							|  |  |  | // execute this code block if expression evalutes to true | 
					
						
							|  |  |  | } | 
					
						
							|  |  |  | else | 
					
						
							|  |  |  | { | 
					
						
							|  |  |  | // always execute this code block when above if expression is false | 
					
						
							|  |  |  | } | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 
 |

										 |  |  | int Price = 30; | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | If (Price = 30) | 
					
						
							|  |  |  | { | 
					
						
							|  |  |  |   Console.WriteLine("Price is equal to 30."); | 
					
						
							|  |  |  | } | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Else  | 
					
						
							|  |  |  | { | 
					
						
							|  |  |  |   Console.WriteLine("Price is not equal to 30."); | 
					
						
							|  |  |  | } | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Since we already declared our int Price to be 30, this will be the expected output. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ## Output
 | 
					
						
							|  |  |  | ``` | 
					
						
							|  |  |  | Price is equal to 30. | 
					
						
							|  |  |  | ``` |
