C＃中的Console.SetBufferSize()方法

Console.SetBufferSize(Int32，Int32)方法用于将屏幕缓冲区的高度和宽度设置为指定的值。

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.

例外情况：

• ArgumentOutOfRangeException ：如果高度或宽度小于或等于零，或者高度或宽度大于或等于MaxValue 。另外，如果宽度小于WindowLeft + WindowWidth或高度小于WindowTop + WindowHeight那么我们将得到相同的异常。
• IOException ：如果发生I / O错误。

注意：在下面的示例中，您将通过水平和垂直滚动条看到，因为我们给出了不同的尺寸，所以我们得到了不同大小的窗口。

范例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
}

输出：

范例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
}

范例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
}
