Keywords are the words in a language that are used for some internal process or represent some predefined actions. void is a keyword, it is a reference type of data type and used to specify the return type of a method in C#. It is an alias of System.Void.
Syntax:
public void function_name([parameters])
{
//body of the function
}
Note: void cannot be used as a parameter if there is no parameter in a C# method.
Example:
Input: Geeks
multi = 50*20
Output: Geeks
multi = 1000
Output: GeeksforGeeks
sum = 80+20
sub = 40-10
Output: GeeksforGeeks
sum = 100
sub = 30
Example 1:
using System;
class GFG {
public void SimpleText()
{
Console.WriteLine( "Geeks" );
}
public void sum( int a, int b)
{
Console.WriteLine( "multi = " + (a * b));
}
};
class Prog {
static void Main( string [] args)
{
GFG ex = new GFG();
ex.SimpleText();
ex.sum(50, 20);
}
}
|
Output:
Geeks
multi = 1000
Example 2:
using System;
using System.Text;
namespace Test {
class Sample {
public void SimpleText()
{
Console.WriteLine( "GeeksforGeeks" );
}
public void sum( int a, int b)
{
Console.WriteLine( "sum = " + (a + b));
}
public void sub( int c, int d)
{
Console.WriteLine( "sub = " + (c - d));
}
};
class Prog {
static void Main( string [] args)
{
Sample ex = new Sample();
ex.SimpleText();
ex.sum(80, 20);
ex.sub(40, 10);
Console.ReadLine();
}
}
}
|
Output:
GeeksforGeeks
sum = 100
sub = 30
