title: If Else Statement
|

# If...Else Statement
|
|
|
|
The If...Else statement executes different blocks of code depending on the truthfulness of the specified condition.
|
|
|
|
|
|
## Syntax
|
|
```C#
|
|
if (boolean expression)
|
|
{
|
|
// execute this code block if expression evalutes to true
|
|
}
|
|
else
|
|
{
|
|
// always execute this code block when above if expression is false
|
|
}
|
|
```
|
|
|
|
## Example
|
|
```C#
|
|
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 integer `Price` to be 30, this will be the expected output.
|
|
|
|
### Output
|
|
```
|
|
Price is equal to 30.
|
|
```
|
|
|
|
## Shortened If...Else Statement
|
|
|
|
We can use the ternary `:?` which is great for short if...else statements.
|
|
|
|
For example:
|
|
```C#
|
|
int Price = 30;
|
|
(Price == 30) ? Console.WriteLine("Price is Equal to 30.") : Console.WriteLine("Price is Not Equal to 30.")
|
|
```
