**Syntax:**

**句法：**

public void function_name([parameters])
    {
    	//body of the function
    }

## C＃代码演示void关键字示例 **(**C\# code to demonstrate example of void keyword**)** ##

using System;
    using System.Text;
    
    namespace Test
    {
        
        class Example
        {
        
            public void printText()
            {
        
                Console.WriteLine("Hello world!");
            }
            public void sum(int a, int b)
            {
        
                Console.WriteLine("sum = " + (a + b));
            }
    
        };
    	
        class Program
        {
        
            static void Main(string[] args)
            {
        
                //calling functions
                Example ex = new Example();
                ex.printText();
                ex.sum(10, 20);
    
                //hit ENTER to exit
                Console.ReadLine();
            }
        }
    }

**Output**

**输出量**

Hello world!
    sum = 30
