Question

我见过关于更改控制台真实类型字体，控制台颜色（rgb）的帖子，但没有设置或获取控制台字体大小。编辑：reason = grid输出到控制台，grid有很多列，更适合更小的字体，想知道是否可以在运行时更改，而不是允许默认或配置字体进行优先级/覆盖继承。

也许this文章可以帮助您

ConsoleHelper.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
using System.Drawing;

namespace ConsoleExtender {
    [StructLayout(LayoutKind.Sequential, Pack = 1)]
    public struct ConsoleFont {
        public uint Index;
        public short SizeX, SizeY;
    }

    public static class ConsoleHelper {
        [DllImport("kernel32")]
        public static extern bool SetConsoleIcon(IntPtr hIcon);

        public static bool SetConsoleIcon(Icon icon) {
            return SetConsoleIcon(icon.Handle);
        }

        [DllImport("kernel32")]
        private extern static bool SetConsoleFont(IntPtr hOutput, uint index);

        private enum StdHandle {
            OutputHandle = -11
        }

        [DllImport("kernel32")]
        private static extern IntPtr GetStdHandle(StdHandle index);

        public static bool SetConsoleFont(uint index) {
            return SetConsoleFont(GetStdHandle(StdHandle.OutputHandle), index);
        }

        [DllImport("kernel32")]
        private static extern bool GetConsoleFontInfo(IntPtr hOutput, [MarshalAs(UnmanagedType.Bool)]bool bMaximize, 
            uint count, [MarshalAs(UnmanagedType.LPArray), Out] ConsoleFont[] fonts);

        [DllImport("kernel32")]
        private static extern uint GetNumberOfConsoleFonts();

        public static uint ConsoleFontsCount {
            get {
                return GetNumberOfConsoleFonts();
            }
        }

        public static ConsoleFont[] ConsoleFonts {
            get {
                ConsoleFont[] fonts = new ConsoleFont[GetNumberOfConsoleFonts()];
                if(fonts.Length > 0)
                    GetConsoleFontInfo(GetStdHandle(StdHandle.OutputHandle), false, (uint)fonts.Length, fonts);
                return fonts;
            }
        }

    }
}

以下是如何使用它来列出控制台的真实字体，

static void Main(string[] args) {
   var fonts = ConsoleHelper.ConsoleFonts;
   for(int f = 0; f < fonts.Length; f++)
      Console.WriteLine("{0}: X={1}, Y={2}",
         fonts[f].Index, fonts[f].SizeX, fonts[f].SizeY);

   ConsoleHelper.SetConsoleFont(5);
   ConsoleHelper.SetConsoleIcon(SystemIcons.Information);
}

关键功能：SetConsoleFont，GetConsoleFontInfo和GetNumberOfConsoleFonts。它们没有证件，因此使用风险自负。

在this线程中，我找到了一个更优雅的解决方案，现在可以正常使用。

ConsoleHelper.cs：

using System;
using System.Runtime.InteropServices;

public static class ConsoleHelper
{
    private const int FixedWidthTrueType = 54;
    private const int StandardOutputHandle = -11;

    [DllImport("kernel32.dll", SetLastError = true)]
    internal static extern IntPtr GetStdHandle(int nStdHandle);

    [return: MarshalAs(UnmanagedType.Bool)]
    [DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
    internal static extern bool SetCurrentConsoleFontEx(IntPtr hConsoleOutput, bool MaximumWindow, ref FontInfo ConsoleCurrentFontEx);

    [return: MarshalAs(UnmanagedType.Bool)]
    [DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
    internal static extern bool GetCurrentConsoleFontEx(IntPtr hConsoleOutput, bool MaximumWindow, ref FontInfo ConsoleCurrentFontEx);


    private static readonly IntPtr ConsoleOutputHandle = GetStdHandle(StandardOutputHandle);

    [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]
    public struct FontInfo
    {
        internal int cbSize;
        internal int FontIndex;
        internal short FontWidth;
        public short FontSize;
        public int FontFamily;
        public int FontWeight;
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]
        //[MarshalAs(UnmanagedType.ByValArray, ArraySubType = UnmanagedType.wc, SizeConst = 32)]
        public string FontName;
    }

    public static FontInfo[] SetCurrentFont(string font, short fontSize = 0)
    {
        Console.WriteLine("Set Current Font: " + font);

        FontInfo before = new FontInfo
        {
            cbSize = Marshal.SizeOf<FontInfo>()
        };

        if (GetCurrentConsoleFontEx(ConsoleOutputHandle, false, ref before))
        {

            FontInfo set = new FontInfo
            {
                cbSize = Marshal.SizeOf<FontInfo>(),
                FontIndex = 0,
                FontFamily = FixedWidthTrueType,
                FontName = font,
                FontWeight = 400,
                FontSize = fontSize > 0 ? fontSize : before.FontSize
            };

            // Get some settings from current font.
            if (!SetCurrentConsoleFontEx(ConsoleOutputHandle, false, ref set))
            {
                var ex = Marshal.GetLastWin32Error();
                Console.WriteLine("Set error " + ex);
                throw new System.ComponentModel.Win32Exception(ex);
            }

            FontInfo after = new FontInfo
            {
                cbSize = Marshal.SizeOf<FontInfo>()
            };
            GetCurrentConsoleFontEx(ConsoleOutputHandle, false, ref after);

            return new[] { before, set, after };
        }
        else
        {
            var er = Marshal.GetLastWin32Error();
            Console.WriteLine("Get error " + er);
            throw new System.ComponentModel.Win32Exception(er);
        }
    }
}

这样您就可以做到：

ConsoleHelper.SetCurrentFont("Consolas", 10);

控制台不支持在运行时更改字体大小。可以找到修改当前控制台窗口设置的可用方法列表on MSDN。我的理解是，这是因为：

控制台不是富文本界面，这意味着它无法显示多种字体或字体大小。
正如Noldorin所说，这应该取决于用户，例如有视力问题的人可以选择大字体。

可以在c＃.net中获取/设置控制台字体大小？
