在C#.NET中,可以使用System.Console
类来获取和设置控制台字体大小。以下是一个简单的示例代码:
using System;
namespace ConsoleFontSizeExample
{
class Program
{
static void Main(string[] args)
{
// 获取当前控制台字体大小
ConsoleFontSize fontSize = ConsoleFontSize.GetFontSize();
Console.WriteLine($"当前控制台字体大小:{fontSize.Width} x {fontSize.Height}");
// 设置新的控制台字体大小
ConsoleFontSize newFontSize = new ConsoleFontSize(12, 12);
ConsoleFontSize.SetFontSize(newFontSize);
Console.WriteLine($"新的控制台字体大小:{newFontSize.Width} x {newFontSize.Height}");
Console.ReadLine();
}
}
public struct ConsoleFontSize
{
public short Width;
public short Height;
public ConsoleFontSize(short width, short height)
{
Width = width;
Height = height;
}
public static ConsoleFontSize GetFontSize()
{
IntPtr hConsoleOutput = GetStdHandle(STD_OUTPUT_HANDLE);
CONSOLE_FONT_INFO fontInfo = new CONSOLE_FONT_INFO();
GetCurrentConsoleFont(hConsoleOutput, false, fontInfo);
return new ConsoleFontSize(fontInfo.dwFontSize.X, fontInfo.dwFontSize.Y);
}
public static void SetFontSize(ConsoleFontSize fontSize)
{
IntPtr hConsoleOutput = GetStdHandle(STD_OUTPUT_HANDLE);
CONSOLE_FONT_INFO fontInfo = new CONSOLE_FONT_INFO();
fontInfo.dwFontSize = new COORD(fontSize.Width, fontSize.Height);
SetCurrentConsoleFont(hConsoleOutput, false, fontInfo);
}
private const int STD_OUTPUT_HANDLE = -11;
[DllImport("kernel32.dll", SetLastError = true)]
private static extern IntPtr GetStdHandle(int nStdHandle);
[DllImport("kernel32.dll", SetLastError = true)]
private static extern bool GetCurrentConsoleFont(IntPtr hConsoleOutput, bool bMaximumWindow, CONSOLE_FONT_INFO lpConsoleCurrentFont);
[DllImport("kernel32.dll", SetLastError = true)]
private static extern bool SetCurrentConsoleFont(IntPtr hConsoleOutput, bool bMaximumWindow, CONSOLE_FONT_INFO lpConsoleCurrentFont);
private struct COORD
{
public short X;
public short Y;
public COORD(short x, short y)
{
X = x;
Y = y;
}
}
private struct CONSOLE_FONT_INFO
{
public int nFont;
public COORD dwFontSize;
}
}
}
在这个示例中,我们首先使用GetFontSize
方法获取当前控制台字体大小,然后使用SetFontSize
方法设置新的字体大小。注意,这个示例仅适用于Windows操作系统。
