# 如果是其他声明
 | 
						||
 | 
						||
If-Else语句根据您的前提条件是否已满,执行代码块。
 | 
						||
 | 
						||
## 例
 | 
						||
```
 | 
						||
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."); 
 | 
						||
 } 
 | 
						||
```
 | 
						||
 | 
						||
由于我们已经宣布我们的int Price为30,这将是预期的产出。
 | 
						||
 | 
						||
## 产量
 | 
						||
```
 | 
						||
Price is equal to 30. 
 | 
						||
 | 
						||
``` |
