Console.SetBufferSize() Method in C#

Last Updated : 14 Mar, 2019

Console.SetBufferSize(Int32, Int32) Method is used to set the height and width of the screen buffer area to the specified values.

Syntax: public static void SetBufferSize(int width, int height);

Parameters:
width: It sets the width of the buffer area measured in the form of columns.
height: It sets the height of the buffer area measured in the form of rows.

Return value: The new size of the buffer screen.

Exceptions:

ArgumentOutOfRangeException: If the height or width is less than or equal to zero Or height or width is greater than or equal to MaxValue. Also, if the width is less than WindowLeft + WindowWidth or height is less than WindowTop + WindowHeight then we will get the same exception.
IOException: If an I/O error occurred.

Note: As you will see via the horizontal and the vertical scrollbars in the below examples, as we give different dimensions, we get differently sized windows.

Example 1:

// C# program to demonstrate 
// the  SetBufferSize Method 
using System; 
using System.Text; 
using System.IO; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // using the method 
        Console.SetBufferSize(800, 800); 
        Console.WriteLine("Start"); 
        while (true)  
        { 
            Console.WriteLine("Great Geek's Example!!!"); 
        } 
    } // end Main 
} 

Output:

Example 2:

// C# program to demonstrate 
// the SetBufferSize Method 
using System; 
using System.Text; 
using System.IO; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        Console.SetBufferSize(0, 80); 
        Console.WriteLine("Great Geek's Example!!!"); 
        Console.WriteLine("The Width's value is too less!"); 
    } // end Main 
} 

Example 3:

// C# program to demonstrate 
// the SetBufferSize Method 
using System; 
using System.Text; 
using System.IO; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        Console.SetBufferSize(8000, -80); 
        Console.WriteLine("Great Geek's Example!!!"); 
        Console.WriteLine("The negativity of this height is unbearable!"); 
    } // end Main 
}
